The promise of 5G is dazzling: blistering speeds, massive device connectivity, and ultra-low latency. At the heart of delivering this, especially for capacity-hungry urban and suburban areas, lies massive MIMO (mMIMO) technology. These advanced antenna arrays, packing 32, 64, or even more elements, aren't just bigger antennas – they're sophisticated beamforming engines. But their performance hinges critically on one often-overlooked factor: the tower they sit on. Forget the "dumb steel pole" mindset. When deploying mMIMO, the inherent design of tubular steel towers unlocks significant RF advantages that concrete or lattice structures simply can't match.
1. Precision Placement & Rigidity: The Foundation of Beamforming
The Challenge: mMIMO relies on precise phase relationships between its many radiating elements to electronically steer focused beams towards users. Any unwanted movement, vibration, or distortion of the antenna platform degrades beamforming accuracy, reducing signal strength, increasing interference, and lowering network capacity.
The Tubular Advantage:
Inherent Rigidity: The continuous, closed cross-section of a tubular steel monopole provides exceptional torsional and lateral stiffness. This minimizes deflection caused by wind, reducing antenna sway and micro-vibrations that disrupt beam patterns.
Precise Mounting Surfaces: Modern tubular towers feature precisely engineered mounting interfaces (e.g., welded mounting plates, specialized brackets). This allows for millimeter-accurate positioning and levelling of heavy mMIMO panels, ensuring the antenna array itself is perfectly planar and stable.
Reduced Structural "Noise": Unlike lattice towers with numerous joints and potential points of flex, the smooth, continuous surface of a tubular tower provides a predictably stable platform, minimizing unpredictable structural movements that confuse beamforming algorithms.
The Challenge: mMIMO arrays require specific spatial configurations for optimal performance. Elements need consistent spacing (often λ/2, where λ is the wavelength) and must be positioned to minimize mutual coupling and pattern distortion. Mounting on irregular or obstructive structures severely hampers this.
The Tubular Advantage:
Clean Cylindrical Profile: The smooth, unobstructed surface of a tubular tower provides an ideal backdrop. Antennas mount flush against the curve, minimizing scattering and reflections that can distort radiation patterns and create unintended sidelobes.
Predictable Near-Field Environment: The uniform curvature and lack of sharp edges/cross-braces create a predictable electromagnetic near-field environment around the antennas. This is crucial for accurate beamforming calculations and minimizing pattern distortion compared to the complex scattering environment of a lattice tower.
Flexible Array Orientation: Tubular towers readily accommodate mounting mMIMO panels in the optimal orientation (e.g., vertical or slightly downtilted columns) without structural interference, maintaining consistent element spacing across the array.
3. Enabling Colocation & Future-Proofing: Density Without Compromise
The Challenge: 5G densification requires packing more sites, often with multiple operators and technologies sharing infrastructure. mMIMO panels are large and heavy. Traditional structures can become cluttered, leading to antenna coupling, blocking, and complex installation challenges.
The Tubular Advantage:
Aerodynamic Efficiency: The sleek, tapered design minimizes wind loading per unit height. This allows tubular towers to be built taller than similarly rated lattice structures, creating more usable vertical real estate.
360-Degree Mounting Potential: The continuous cylindrical surface provides ample, obstruction-free space around the entire circumference. This allows for the strategic placement of multiple mMIMO panels (potentially for different operators or frequency bands) at optimal heights and azimuths without significant mutual blockage or coupling.
Structural Headroom: Designed with significant load margins, modern tubular towers easily accommodate the weight and wind load of multiple large mMIMO panels, plus future additions like mmWave radios or additional arrays, simplifying network evolution.
4. Aesthetics Meets RF Performance: The Hidden Link
The Challenge: Municipalities demand low visual impact, especially in dense urban or scenic areas. Bulky lattice towers or large concrete bases are often visually unacceptable. RF performance shouldn't suffer due to aesthetics.
The Tubular Advantage:
Sleek, Minimalist Profile: The slender, monopole design has the smallest possible visual footprint, making it the preferred choice for restrictive zoning areas. This isn't just about looks; it means towers get approved and deployed where needed most.
No RF Sacrifice: Crucially, achieving this aesthetic acceptance does not come at the cost of RF performance. The structural and mounting advantages inherent to the tubular design are maintained, ensuring mMIMO can perform optimally even on the most discreet structures. The visual benefit is a direct enabler of optimal RF site placement.
Specification is Key: Maximizing the mMIMO Advantage on Tubular Towers
To fully leverage these RF benefits, precise specification is essential:
Demand High Rigidity: Specify deflection limits under wind load relevant to mMIMO stability (e.g., top deflection < height/200 for operational winds).
Precision Mounting Systems: Require engineered mounting solutions (plates, brackets) designed for specific mMIMO panel weights, dimensions, and mounting patterns, ensuring perfect levelling and stability.
Corrosion Protection: Specify robust systems like Zn-5%Al coating and cathodic protection (as highlighted in our coastal article) to ensure long-term structural integrity and prevent rust-induced distortions or mounting point failures.
Adequate Height & Diameter: Ensure sufficient tower height for clear RF pathways and a base diameter large enough to provide stable mounting real estate for current and future mMIMO arrays.
Professional Installation: Mandate certified installers using calibrated equipment to guarantee precise antenna positioning and alignment according to the tower manufacturer's specifications.
Conclusion: The Intelligent Foundation for Intelligent Networks
Deploying 5G mMIMO isn't just about bolting on advanced antennas; it's about creating the optimal electromagnetic environment for them to perform. Tubular steel towers are far more than passive supports. Their inherent rigidity, clean electromagnetic profile, flexible mounting real estate, and aesthetic acceptance make them the engineered foundation for unlocking the full potential of mMIMO beamforming. By understanding and specifying for these "beyond the surface" RF optimization secrets, network operators can build higher-performing, more reliable, and future-proof 5G networks that truly deliver on the promise. Don't let your tower be the weakest link in your mMIMO strategy.

“Aluminum lattice towers aren’t just lightweight – they’re a total ecosystem solution: reducing installation carbon footprint by 63%, eliminating lifetime maintenance, and accelerating ROI.” ― Altai Engineering Group
The Physics of Stability While self-supporting towers rely on rigid foundations to resist wind loads, guyed mast towers leverage a triangular tension system to achieve unparalleled stability:
Dynamic Load Distribution: Guy wires convert lateral wind forces (up to 150 km/h) into vertical tension, reducing tower shaft stress by 60% versus self-supporting designs.
Anti-Overturning Mechanism: Each wire anchor acts as a pivot point, creating counter-moments that neutralize torsion during storms. At 40m height, a 3-anchor system provides 360° load balancing with just 25% steel usage of lattice towers.
Savings enable 3x more sites per budget – critical for universal service obligations.
When Guyed Towers Aren't Ideal
Urban Microcells: Land constraints make anchor footprints (20m dia.) impractical
Multi-Operator Sites: Limited top-platform space struggles beyond 6 antennas
Vandalism-Prone Areas: Exposed guy wires require tamper-proof monitoring
The Verdict Guyed towers aren't just "cheap" – they're strategically optimized for UHF's long-range physics. By marrying tensile efficiency with terrain flexibility, they deliver coverage where traditional towers can't compete. As 5G expands into unserved territories, these unsung heroes will remain the backbone of inclusive connectivity.
For project planners: Prioritize hot-dip galvanized steel (ISO 1461) and helical screw anchors in sandy soils. Always budget for tension monitoring systems – loose guys cause 73% of failures.
Concrete: the seemingly indestructible backbone of modern infrastructure. Yet, place it on a saline coast, and a silent war begins. Salt-laden air and moisture penetrate pores, triggering corrosion of the embedded steel rebar. This rust expands, cracking the concrete from within – a process called spalling. What looks solid becomes dangerously compromised, often with little external warning until catastrophic failure looms. In the relentless battle against coastal corrosion, concrete has a critical vulnerability.
This is precisely why tubular steel towers, armed with advanced protection systems, are becoming the undisputed champions for critical structures like telecom towers in these harsh environments. Let's break down their winning defenses:
The Zn-5%Al Alloy Coating: The First Line of Defense
What it is: A metallic coating consisting of 95% Zinc and 5% Aluminum, often applied via hot-dip galvanizing to tubular steel sections.
Why it wins vs. Salt:
Barrier Protection: Creates a dense, continuous physical barrier shielding the underlying steel.
Galvanic Sacrifice: Zinc preferentially corrodes, protecting the steel (like standard galvanizing).
Aluminum's Superpower: Aluminum forms stable, highly adherent oxide layers (Al₂O₃) that significantly slow down the corrosion reaction itself. This is crucial against the constant chemical assault of chlorides.
Self-Healing Potential: The Zn-Al alloy offers better "flow" during application and potentially better healing of minor scratches than pure zinc coatings.
Longevity: Zn-5%Al coatings demonstrably outperform standard zinc coatings (Zn-100%) in saline atmospheres, offering significantly extended service life before maintenance is needed. Studies show life extensions of 50-100% or more compared to traditional galvanizing in marine settings.
Cathodic Protection (CP): The Active Shield
What it is: An electrochemical technique that forces the entire steel structure to become the cathode in a corrosion cell, halting the corrosion reaction.
How it Works with Towers:
Sacrificial Anodes: Blocks of a more reactive metal (like Zinc or Magnesium alloys) are attached directly to the tower's foundation or lower sections. These anodes corrode sacrificially instead of the steel. The Zn-5%Al coating acts synergistically, becoming part of this protective system.
Impressed Current CP (ICCP): For very large or critical structures, a low DC current is applied from an external power source through inert anodes, actively polarizing the steel to a protective state.
Why it Wins vs. Salt: CP is highly effective in electrolyte-rich environments like damp, saline soil or splash zones. It provides active, ongoing protection, even if the primary coating is locally damaged. It's the essential "insurance policy" for decades-long durability.
The Cost of Concrete Failure: Lessons from the Coastlines
The Philippines: Tropical storms combined with pervasive salt spray create a nightmare for infrastructure. Numerous concrete telecom tower bases, especially older or less well-maintained ones, suffer severe spalling and rebar corrosion. This leads to:
Emergency structural repairs or rebuilds, causing significant network downtime.
Skyrocketing long-term maintenance costs as patchwork fixes struggle against relentless decay.
Safety hazards from falling concrete chunks or potential structural collapse.
The Middle East: While often drier, the combination of extreme coastal humidity, high temperatures accelerating chemical reactions, and frequent sandstorms (abrading surfaces) creates a uniquely aggressive environment. Corrosion rates on unprotected or poorly protected steel and concrete can be shockingly high. Premature degradation of concrete foundations supporting various structures is a well-documented, costly issue.
Tubular Steel: Engineered for Victory
Beyond superior corrosion protection, tubular steel towers offer inherent advantages perfectly suited for challenging coastal deployments:
Strength-to-Weight Ratio: Steel provides immense strength with less bulk compared to concrete. This allows for taller, more slender structures capable of handling heavy antenna loads and high winds.
Foundation Flexibility: Requires significantly smaller, less invasive foundations than heavy concrete structures, crucial for unstable coastal soils or sensitive environments.
Aesthetics & Space Saving: The sleek design drastically reduces visual impact and physical footprint.
Proof in Performance: The Dubai Waterfront Advantage
Consider this compelling real-world validation from a demanding coastal megaproject:
"Dubai's ambitious waterfront development faced the dual challenge of harsh salt-laden winds and premium land costs. By deploying tapered tubular steel monopoles (diameter tapering from 1.2m at the base to 0.4m at the top) protected with Zn-5%Al coatings and integrated cathodic protection systems, the project achieved remarkable outcomes vs. traditional lattice (angle steel) towers:
40% Increase in Wind Load Resistance: The inherent strength and aerodynamic efficiency of the tubular design handled coastal gusts far more effectively.
70% Reduction in Visual Footprint: The sleek monopoles blended into the upscale waterfront environment, a critical planning approval factor.
$2.8 Million Saved in Land Costs: The drastically smaller base footprint allowed colocation of 12 different operators' equipment on single, efficient towers, avoiding the need for multiple large tower plots on extremely valuable land."**
The Verdict for Saline Sites
Concrete's hidden vulnerability to chloride attack makes it a risky long-term proposition for critical coastal infrastructure like telecommunication towers. The combination of advanced metallic coatings (Zn-5%Al) and robust cathodic protection transforms tubular steel towers into the corrosion-resistant champions of these demanding environments. They deliver not just superior durability and safety, but also tangible benefits in performance, space utilization, aesthetics, and ultimately, significant cost savings over the asset's lifetime.
When failure isn't an option on the salty coast, the choice is clear: engineered tubular steel stands tall. Specify Zn-5%Al and CP – it's the investment that withstands the elements.
Why Utility Steel Poles Are Revolutionizing Low-Voltage Grids: Replacing the Concrete Standard
For decades, concrete poles were the familiar backbone of low-voltage power distribution. But look around newer installations or upgraded grids today, and you'll increasingly see sleek, galvanized steel tubular poles taking their place. This shift isn't just aesthetic; it's driven by compelling technical and economic advantages. Let's break down why steel tubular poles are becoming the new standard.
1. Material Performance: Strength & Stiffness Where It Counts
Concrete Poles: Concrete excels in compression but is inherently brittle and weak in tension. This makes it vulnerable to cracking from impact (vehicle collisions, falling branches), ground movement, or even internal stresses. Its stiffness is fixed once cast.
Steel Tubular Poles: Steel offers exceptional tensile strength and toughness. It bends significantly before failing, providing inherent resilience against impact and wind loads. Its high stiffness combined with ductility allows it to absorb energy safely. The tubular design efficiently distributes loads, maximizing strength with minimal material.
Winner: Steel. Superior tensile strength, ductility (safety), and resilience make it fundamentally better suited for the dynamic loads poles face.
2. Strength-to-Weight Ratio: A Game Changer
Concrete Poles: Heavy! A typical 10-12m concrete pole for LV lines can weigh 300-500 kg or more. This bulk dictates everything else.
Steel Tubular Poles: Dramatically lighter. A comparable steel pole might weigh only 100-200 kg – often 3-5 times lighter for the same functional strength and height. This high strength-to-weight ratio is perhaps steel's most significant advantage.
Winner: Steel. By a massive margin. This lightweight nature cascades into benefits across installation, transport, and foundation needs.
3. Lifespan & Durability: Built to Last (with Protection)
Concrete Poles: Susceptible to weathering, freeze-thaw cycles, and corrosion of internal reinforcement (rebar) if cracks allow water ingress. Spalling (surface chunks breaking off) is common over time, weakening the structure. Lifespan is typically 30-50 years but can be shorter in harsh environments.
Steel Tubular Poles: The key is hot-dip galvanization. This thick, bonded zinc coating provides exceptional, long-term corrosion protection, easily lasting 50+ years in most environments. The steel itself is inherently resistant to weathering and freeze-thaw damage. Minor surface scratches don't compromise the entire structure like cracks in concrete.
Winner: Steel. With proper galvanization, steel poles offer superior, predictable longevity and lower maintenance needs.
4. Installation Efficiency: Speed and Simplicity
Concrete Poles: Require heavy lifting equipment (cranes) due to their weight. Foundations often need significant excavation and concrete pouring, curing time, and backfilling. Handling is cumbersome and potentially hazardous.
Steel Tubular Poles: Their light weight allows for installation using smaller, more maneuverable equipment (e.g., bucket trucks with augers/hoists). Foundations are much smaller and simpler – often just drilled holes with compacted backfill or small concrete pads. Factory prefabrication ensures consistent quality and includes pre-drilled holes for accessories, speeding up assembly on-site.
Winner: Steel. Faster installation, reduced labor, less disruptive groundwork, and lower equipment requirements translate to significant project time savings.
5. Cost-Effectiveness: Looking Beyond the Initial Price Tag
Concrete Poles: Often have a lower initial purchase price per pole. However...
Steel Tubular Poles: While the unit pole cost might be slightly higher, the total installed cost is frequently lower or competitive due to:
Drastically reduced foundation costs (less excavation, less concrete).
Faster installation (lower labor and equipment rental costs).
Reduced transportation costs (more poles per truckload).
Lower long-term maintenance costs (less susceptibility to damage, no spalling repairs).
Longer lifespan reduces replacement frequency.
Winner: Steel. Offers superior lifecycle value. The savings in foundations, installation, and maintenance often outweigh the slightly higher material cost.
The Driving Forces: Why the Shift is Happening Now
Space Constraints & Urbanization: Steel poles' smaller foundations and ability to be installed closer to obstacles are crucial in dense urban areas and congested rights-of-way.
Resilience Demands: Superior strength and ductility make steel poles more resistant to extreme weather events (high winds, ice) and accidental impacts, improving grid reliability.
Rapid Deployment Needs: The speed of installation is vital for grid upgrades, expansion projects, and disaster recovery.
Total Cost Awareness: Utilities increasingly prioritize lifecycle costs over simple upfront costs, recognizing the long-term savings steel offers.
Aesthetics (Bonus): Steel poles offer a cleaner, more modern appearance, which is often preferred in community settings.
Conclusion: A Superior Solution for Modern Grids
The transition from concrete to steel tubular poles in low-voltage networks isn't a fleeting trend; it's a rational response based on clear engineering and economic advantages. Steel's superior material properties – especially its high strength-to-weight ratio – combined with the benefits of factory prefabrication, easier installation, proven long-term durability through galvanization, and compelling lifecycle cost savings make it the smarter choice for building resilient, efficient, and cost-effective power distribution infrastructure for the future. While concrete poles served well historically, steel tubular poles represent the technological evolution needed for modern grid demands.

Prefabricated houses, also known as modular or earthquake container house, are innovative structures designed and constructed in sections (modules) in controlled factory environments before being transported and assembled on-site. Their design prioritizes seismic resilience, making them ideal for regions prone to earthquakes. Here’s how they address seismic challenges:
1. Structural Design for Earthquakes
Prefabricated homes often use flexible, durable materials like steel frames, engineered wood, or composite materials. These materials absorb seismic energy, reducing the risk of collapse. Their modular components are connected with energy-dissipating joints and reinforced connections, allowing the structure to sway during tremors without breaking—key to withstanding lateral forces. Unlike traditional masonry, which is brittle, prefab structures have a higher strength-to-weight ratio, minimizing inertial forces during quakes.
2. Precision Engineering & Quality Control
Factory-based construction ensures strict adherence to seismic codes . Each module is tested for structural integrity, including resistance to dynamic loads simulating earthquake movements. This precision reduces human error in construction, a common factor in non-prefab buildings’ failure during seismic events.
3. Foundation & Base Isolation Systems
Many prefabricated homes incorporate seismic base isolation techniques. Rubber or steel bearings are installed between the foundation and the main structure, absorbing and dissipating earthquake energy. This “decoupling” reduces vibrations transmitted to the building, protecting both the structure and its occupants. For areas with soft soil, shallow foundations or screw piles are used to improve stability and load distribution.
4. Rapid Deployment for Post-Quake Relief
In disaster zones, prefabricated houses shine for their quick assembly. Modules can be transported and erected in days or weeks, providing urgent shelter compared to months-long traditional construction. This is critical for post-earthquake recovery, offering safe, temporary container housing while minimizing disruption to affected communities.
5. Sustainability & Adaptability
Beyond seismic safety, these homes are often eco-friendly, using recycled materials and energy-efficient designs. Their modular nature allows easy expansion or modification, adapting to changing needs—an advantage in regions where aftershocks or future quakes may require structural adjustments.
Challenges & Innovations
In summary, prefabricated houses merge engineering precision with seismic design to create safe, sustainable, and rapidly deployable solutions, offering hope and security in earthquake-prone areas worldwide.
At a precast concrete component factory, a wall panel weighing several tons is steadily lifted, rotated, and precisely positioned by a crane. Behind this seemingly effortless movement lies a crucial engineering decision: the type of steel used for the anchor bolts. Bare steel, hot-dip galvanized steel, or electrogalvanized steel—these seemingly ordinary metals are, in fact, the "lifeline" that bears immense weight. Choosing the wrong anchor bolt can cause a component to fall, delay construction, or even lead to a major safety incident.
The Iron Armor Trio: The Technical Secrets Behind the Coating
1. Bare Steel Anchor Bolts: The Double-Edged Sword of Raw Strength
Bare steel anchor bolts, untreated and forged from high-strength alloy steel, offer advantages in ultimate tensile strength (typically reaching 800-1000 MPa) and cost-effectiveness. However, their fatal weakness is their alarming corrosion rate in humid environments. Laboratory data shows that after three months of exposure to humidity >60%, their surface exhibits visible red rust and their tensile strength decreases by 15%. Therefore, they are only suitable for temporary installation in dry indoor environments or as temporary fixtures during concrete pours (which are then covered).
2. Hot-Dip Galvanized Steel Anchor Bolts: A Guardian of Heavy-Duty Environments
The production process can be described as a "molten lava bath for steel": After undergoing seven cleaning steps (degreasing, pickling, and fluxing), the anchor bolts are immersed in a 460°C molten zinc bath, forming an 80-100μm zinc-iron alloy layer. This process offers three major advantages:
- Sacrificial anodic protection: The zinc layer corrodes preferentially, protecting the underlying steel and offering a lifespan of 20-50 years.
- Mechanical bonding: The zinc penetrates the micropores of the steel surface, creating an adhesion 10 times stronger than electroplating.
- Full coverage: Even thread gaps are sealed with the zinc layer, leaving no blind spots.
The trade-off is a potential loss of 5%-8% in strength due to high-temperature annealing, and a rough surface with zinc nodules (requiring special gaskets to prevent scratches).
3. Electrogalvanized Steel Anchor Bolts: Elegant Guardians of Precision Environments
In an electrochemical bath, an electric current drives the deposition of zinc ions, forming a mirror-like coating just 10-12μm thick. Its core values lie in:
- Zero thermal deformation: The room-temperature process maintains the steel's original strength (particularly suitable for ultra-high-strength steels above 1000 MPa).
- Smooth surface: Reduces wear on slings and extends cable life by 30%.
- Precision dimensions: Uniform coating ensures no loss of thread fit.
However, salt spray tests show that its corrosion resistance is only one-fifth that of hot-dip galvanizing under similar conditions, and its outdoor service life typically does not exceed five years.

Beware—The Devil is in the Details: Four Pitfalls in Coating Application
1. Compatibility Pitfall: Hot-dip galvanized anchors can cause electrochemical corrosion (average corrosion depth of 0.2mm per year) when in contact with aluminum formwork. Solution: Use nylon isolation gaskets or switch to an all-stainless steel system.
2. Magnetic Attenuation Blind Spot: Residual concrete or oil on the galvanized surface can reduce the magnetic hanger's grip by 40%. Cleaning must be done with a stainless steel scraper (iron tools are prohibited to prevent magnetization).
3. High-Temperature Operation Risk: When using hot-dip galvanized anchors near a steam curing kiln, temperatures exceeding 80°C can cause the zinc layer to demagnetize. A PC manufacturer in northern China experienced anchor failure due to winter steam curing. This issue was resolved by switching to high-temperature-resistant models with neodymium magnets (operating at 150°C).
4. Identifying Fake Galvanizing: Poor-quality electroplated zinc coatings with a thickness of less than 5μm can be detected with a magnetic thickness gauge (the standard requirement is ≥10μm).
Therefore, it's crucial to prioritize industry standards and compliance.
Both hot-dip galvanized and electrogalvanized lifting anchors are subject to various industry standards and regulations to ensure their safety and performance in lifting operations.
For example, in Australia, lifting anchors must comply with AS 3850.1:2015, which outlines specific requirements for the manufacture, testing, and use of lifting anchors in construction, ensuring they are safe, reliable, and meet quality expectations. This standard includes provisions for the proper use of uncoated and coated steel, emphasizing the importance of corrosion protection in the structural integrity of lifting systems.
Similarly, in the United States, ASTM A123/A123M governs the hot-dip galvanizing process, ensuring that coating thickness and quality meet corrosion protection requirements. ASTM B633, which applies to electroplating, including electrogalvanizing, specifies coating thickness, adhesion, and performance for various applications. These standards provide guidance for selecting the appropriate corrosion protection method based on environmental exposure and mechanical load requirements.
Lifting anchor manufacturers must adhere to these standards to ensure their components meet safety and durability expectations, especially in corrosion-prone environments. Adherence to these industry standards ensures contractors and engineers can trust the performance and longevity of the products they use, avoiding the costly and dangerous consequences of steel failure due to rust.
Finally, a scenario-based selection guide: Making every anchor bolt the right one for the job.
🏗️ Preferring hot-dip galvanized anchor bolts
- Highly corrosive environments: Coastal buildings, chemical plants, freeze-thaw zones (corrosion from de-icing agents)
- Heavy-load lifting: Large beams and columns weighing >5 tons, double-T-plates (requires a 2100kg-class magnetic system)
- Full lifecycle management: General-purpose anchor bolts that require reusability (e.g., assembly line molds)
⚡ Preferring electrogalvanized anchor bolts
- Precision components: Decorative concrete slabs (surface zinc nodules are not permitted)
