What Is Galvalume Steel?
Galvalume steel, also known as Aluminum-Zinc Alloy Coated Steel, Zincalume steel, aluminized zinc steel (aluzinc steel), or SGLC, is composed of 55% aluminium, 43.4% zinc and 1.6% silicon solidified at 600°C. Its structure consists of aluminium-iron-silicon-zinc, forming a compact quaternary crystal alloy. The surface of galvalume steel sheet is characterized by smooth, flat appearance with a silver-white base color. The special coating structure provides excellent corrosion resistance with a normal service life of up to 25 years. It offers good heat resistance for use in high temperature environments up to 315°C, excellent paint adhesion, and good processing performance for punching, shearing, and welding operations. The surface conductivity is very good.

Frequently Asked Questions
1. Is Galvalume steel fire-resistant?
Yes, Galvalume is a non-combustible material and typically carries a Class A fire rating, making it ideal for roofing and industrial structures.
2. Does Galvalume have "self-healing" properties?
Yes. Thanks to the zinc component, Galvalume provides sacrificial protection at cut edges or scratches, preventing rust from spreading into the steel core.
3. Can Galvalume withstand high temperatures?
Extremely well. It can resist oxidation and remain structural at temperatures up to 315°C (600°F) without discoloration, and even higher for short periods.
4. What are the primary uses of Galvalume?
It is widely used for metal roofing, siding, pre-engineered metal buildings, HVAC ductwork, automotive parts, and appliances.
5. Can Galvalume be used near the ocean?
While highly durable, it is generally not recommended for use within 1,500 feet (approx. 500m) of severe marine environments where salt spray is constant, as salt can accelerate the breakdown of the aluminum oxide layer.
