Products Description

It is produced through a process of metal coating which involves passing cold rolled coils through a kettle containing molten Alu-zinc. This process ensures adhesion of Alu-zinc to the surface of the steel sheet. The Alu-zinc layer provides excellent corrosion resistance and prolongs service life. People often call it as SGCC/SGCH/DX51D/ JIS G3302 full hard galvalume coils,AZ coating 40-150g/m2 galvalume steel coils and full hard galvalume.


Features

Beauty: because of it has a high thermal reflectance, twice as much as galvanized steel, and is often used as a heat-insulating material. The surface is unique smooth, flat and luxuriant spangle, base color is silvery white. 

Good quality: the special coating structure has excellent corrosion resistance. The normal service life of galvalume steel plate can be up to 25 years, good heat resistance, and can be used in 315 high temperature environment. 

Wide application: the coating has good adhesion to the paint film, and has good processing properties, which can be used for stamping, cutting, welding, etc. The surface conductivity is very good.

Galvalume stee coil is pre-coated by hot-plating for Alu-zinc coatings both sides and has mass percentage of about 55% Aluminum, 43.5% zinc, 1.5% Si, combined with physical protection and integration of high durablity and electrochemical protection features of Al and Zn to obtain the substrate metal’s strength and ductility but also corrosion resistance of the coating.It not only can protect the inner metal base from corrosion but also the surface was highly decorative bright silver gray and the regular spangle and has a bumpy sense.

When the steel roll happens trimming, scratches and abrasions, the zinc will take the role of sacrificial coatings to protect the steel’s anti-corrosion, the aluminum will form an oxide insoluble protection barrier layer. Aluminum zinc alloy steel coil has been in a variety of different atmospheric environment, carried out more than 20 years of outdoor exposure test, it is confirmed that 55% galvanized steel roll trimming protection function is better than galvanized steel and 5% aluminum zinc steel.

Galvalume steel’s unique protective characteristics and economical price point make it ideal for residential and commercial exterior building products, including roofing, siding and cabinetry.
