Vitrafix Zinc-Al-Mag
Coated Steel Sub-framing

ZAM 120 Tophat-1

Coating

Advanced Zinc-Al-Mag triple alloy coating delivers superior edge protection and slower corrosion rates compared to traditional galvanised steel, particularly in coastal and industrial environments.

System Integration

Designed as part of Fairview’s tested Vitrafix facade systems, ensuring seamless compatibility with cladding panels, insulation, sarking, fixings and accessories.

Warranty

25-year warranty, subject to standard terms and conditions.

Application

Suitable for use in external facade sub-framing across residential, commercial and infrastructure projects, including coastal, industrial and high-humidity environments where durability and compliance are critical.

Zinc-Al-Mag type coatings as a next-generation alternative to galvanised steel, offering significantly improved durability and stability. Fairview’s Vitrafix Zinc-Al-Mag Top Hats apply this advanced triple alloy technology to deliver superior structural reliability, long-term corrosion resistance and confidence that the façade will perform as designed throughout its service life. Its stable performance reduces the likelihood of premature deterioration, while the limited need for ongoing maintenance contributes to more cost-efficient project outcomes. The balance of durability and value makes Vitrafix Zinc-Al-Mag ideal for demanding environments, such as coastal and industrial locations.

As an integral part of Fairview’s facade systems, Vitrafix Zinc-Al-Mag Top Hats work seamlessly with cladding panels, insulation, sarking, fixings, and accessories to form a complete assembly. Thorough testing guarantees consistent performance, compliance with Australian standards and reduced long-term maintenance. By combining technical performance with ease of integration, Fairview’s Vitrafix Zinc-Al-Mag sub-framing provides designers, engineers and builders with confidence that their facade systems will deliver lasting performance and value.

Zinc-Al-Mag Benefits

Corrosion Resistance
The Zinc-Al-Mag coating delivers superior multi-layer corrosion protection. Zinc protects the steel substrate, while aluminium and magnesium form a dense film that spreads over exposed areas, including cut edges, to prevent further corrosion and outperform standard galvanised steel.
Long Service Life
By sealing vulnerable areas and slowing corrosion rates, the coating maintains structural integrity for extended periods. This self-healing process significantly reduces the risk of premature failure in harsh environments such as coastal, industrial and high-humidity zones
Cost Efficient
The combination of sacrificial zinc protection and self-healing Al-Mg film minimises maintenance and repair needs. Longer durability lowers whole-of-life costs, making Vitrafix Zinc-Al-Mag Top Hats a practical and economical choice for compliant building systems.
