Galvanized steel sheet-DX51D+AZ is used for?
Construction: such as roof panels, wall panels, and purlins, which use their weather resistance to resist rain and atmospheric corrosion and extend the life of outdoor structures;
Home appliance manufacturing: refrigerator and air conditioner shells and internal components, which are not only resistant to moisture and rust, but also can achieve beautiful appearance through painting;
Automotive industry: body floor and chassis parts, which resist road mud and salt erosion and improve the durability of the whole vehicle;
Furniture and decoration: cabinets, shelves, etc., which are easy to process into complex shapes due to their formability, and the coating protection reduces daily wear and rust.
What is steel grade DX51D equivalent to?
DX51D steel grade is equivalent to Japanese standard SGCC.
DX51D is the steel grade code in the European standard. "D" means flat steel for cold forming, "X" means the rolling state of the base material is not specified, "51" means the steel grade number, and "D" is the hot-dip galvanizing code. It uses low-carbon steel as the base material and is mainly used for bending and forming; SGCC is the Japanese standard code for hot-dip galvanized thin steel sheets, where S means steel, G means galvanizing, C means cold rolling, and the fourth C means ordinary grade. Both are widely used in the construction, home appliances, automobile and other industries to manufacture parts with certain requirements for corrosion resistance and formability.
How thick is AZ150 coating?
AZ150 is the coating weight code for Galvalume Aluzinc Steel Sheets in Coils (55% aluminum-43.4% zinc-1.6% silicon), indicating that the total weight of the double-sided coating is 150g/m². The single-sided coating thickness is approximately 10-12 microns (μm)
How thick is galvalume sheet coating?
AZ100: coating weight 100g/m² (double-sided), average coating thickness on one side is about 13μm.
AZ150: coating weight 150g/m² (double-sided), average coating thickness on one side is about 20μm.
AZ185: coating weight 185g/m² (double-sided), average coating thickness on one side is about 25μm.
