ASTM A792/A792M is a standard for 55 % aluminum-zinc alloy coated steel sheet in coils and cut lengths. This product is intended for applications requiring corrosion resistance or heat resistance, or both. The product is produced in a number of designations, types, and grades which are designed to be compatible with differing application requirements.
Galvalume steel is also called Aluminum-Zinc Alloy Coated Steel, aluminized zinc steel (aluzinc steel) ,SGLC, The galvalume metal is composed of 55% aluminium , 43.4% zinc and 1.6% silicon solidified at 600℃. Its whole structure consists of aluminium-iron-silicon-zinc , forming a compact quaternary crystal alloy. The surface of the galvalume steel sheet is characterized by smooth,flat and gorgeous stars, and its base color is silverwhite. The special coating structure makes it have excellent corrosion resistance. The normal service life of galvalume steel sheet is up to 25a, and its heat resistance is good. It can be used in high temperature environment at 315℃. The adhesion between coating and paint film is good, and it has good processing performance. It can be punched, sheared and welded. The surface conductivity is very good .

Galvalume coated steel
advantages of Aluminum-Zinc Alloy Steel
1. Specifications can be customized according to customer requirements.
2. Perfect corrosion resistance. The service life of galvanized sheets is 3-6 times that of galvanized sheets.
3. Perfect processing performance. Fully meet the requirements of roller processing, stamping, bending and so on.
4. Perfect light reflection. Twice the ability to reflect light and heat than galvanizing.
5. Perfect heat resistance. Galvalume products can be used for long periods of time at 315 degrees Celsius without discoloration.
6. Excellent adhesion between paints. Easy to paint and can be painted without pre-treatment and weathering.
