Foire aux questions – Aluminum Decking Planks
❓ What Does A2-s1, d0 Fire Rating Mean, and Why Is It Critical for Building Safety?
Our GD Aluminum Decking achieves A2-s1, d0 fire rating in accordance with BS EN 13501-1 et EN ISO 9239-1 standards. This classification means:
- Non-Combustible Material – The decking will not ignite or contribute to fire spread
- Limited Smoke Production – Produces minimal smoke (s1) in fire conditions
- No Flaming Droplets – Does not produce flaming droplets or particles (d0)
- Highest Safety Classification – A2 is the second-highest fire performance class, suitable for critical applications
This fire rating is mandatory for high-rise residential buildings, commercial developments, hôpitaux, écoles, and public spaces. Unlike traditional wooden decking (which is combustible), our aluminum decking eliminates fire risk entirely, making it the preferred choice for architects and building inspectors in jurisdictions with strict fire codes (US, EU, UK, Australia, etc.).
❓ What Premium Coating Systems Are Used, and How Long Will the Finish Last?
GD Aluminum Decking is finished with premium industrial-grade powder coating systems from leading manufacturers including AkzoNobel et Tiger Coatings. These coatings provide:
- Superior Weather Resistance – Withstands UV exposure, salt spray, humidity, and extreme temperature fluctuations
- Corrosion Protection – Multi-layer coating system prevents oxidation and aluminum degradation
- Color Retention – Maintains vibrant appearance for 10-15 years in harsh outdoor environments
- Faible entretien – Requires only occasional cleaning with water and mild soap
- Environmental Compliance – VOC-free and compliant with EU and North American environmental standards
Our standard warranty covers 10 years of coating durability under normal use conditions. Extended warranties up to 15-20 years are available for premium applications. The coating thickness typically ranges from 60-80 microns, significantly exceeding industry minimums (typically 25-40 microns), ensuring exceptional longevity in coastal, industrial, and high-traffic environments.
❓ What Aluminum Alloy Is Used in GD Decking, and How Does It Compare to Other Materials?
GD Aluminum Decking is manufactured from 6063-T6 aluminum alloy, the premium choice for architectural and structural applications. The T6 heat treatment provides:
- High Strength – Tensile strength of 215 MPa, supporting heavy loads while maintaining lightweight profile
- Excellent Corrosion Resistance – Superior to standard aluminum (6061-T6) in salt-spray and humid environments
- Superior Extrudability – Enables complex profile designs with tight tolerances and smooth surfaces
- Better Formability – Allows for curved and custom shapes without cracking
Comparison to alternatives:
- vs. Wooden Decking: Aluminum is non-combustible, rot-proof, splinter-free, and requires zero maintenance. Lifespan: 50+ years vs. 10-15 years for treated wood.
- vs. Composite Decking: Aluminum is lighter, stronger, fully recyclable, and maintains its appearance without fading. No off-gassing or environmental concerns.
- vs. PVC/Plastic Decking: Aluminum offers superior strength-to-weight ratio, better thermal performance (cooler underfoot), et 100% recyclability.
Each batch of 6063-T6 aluminum is certified with Rapports d'essais d'usine (MTR) verifying chemical composition, mechanical properties, and batch traceability. Nous maintenons une transparence totale de la chaîne d'approvisionnement pour répondre à vos exigences d'approvisionnement et à vos spécifications techniques..
