Product Performance: Super corrosion resistant
The samples of Wuxi City Product Quality Supervision and Inspection Institute conducted salt spray test. The galvanized steel strip showed red rust after 384 hours, while the super corrosion-resistant zinc-aluminum-magnesium alloy coated steel strip did not see red rust after 1000 hours. Compared with ordinary galvanized products, it can achieve better corrosion resistance, which is 3 to 5 times that of hot-dip galvanized steel.
100g, 275g ultra-corrosion-resistant zinc-aluminum-magnesium alloy coated steel strip has no red rust on the surface for 1000h
Red rust on the surface of 275g galvanized steel strip 384h
Super corrosion resistance: Salt spray test
02
Product performance: Self-healing
The coating components around the cutting surface and the punching surface can automatically dissolve out and form a dense protective film to cover the cut end surface, incision and embroidered parts, realizing automatic repair of the alloy coating.
耐蚀性比较
The coating components automatically dissolve and form a dense protective film to continuously cover the end surface or cut
Form a dense protective film to completely cover the end face or cut and red rust parts
Self-healing function: cut or end face
03
Product performance: Zinc-free
The ultra-corrosion-resistant zinc-aluminum-magnesium alloy coated steel plate (strip) has no spangles, and the surface coating is dense and flat, which is beneficial for subsequent personalized processing and advanced coating after the plate (strip) is formed.
The welding process is resistance lap welding, and the weld quality is good
Zinc-free--easy welding process
04
Product performance: Strong attachment
The coating of hot-dip galvanized aluminum-magnesium steel is denser than that of galvanized steel, so it is not easy to peel off the coating during the stamping process. It has excellent tensile, stamping, bending, welding and other processing properties under severe conditions, and due to the coating The hardness is high, so it has excellent damage resistance.
180° bending test: no coating peeling off on the curved outer surface
Complicated bending test: the steel plate has good bending performance and good coating
- Strong attachment：Bending test
- Strong attachment：Complex bending test
05
Product performance: Safety and environmental protection
This product adopts the ecological water washing method to remove rust, and realizes the green and safe environmental protection production process. The product coating does not contain heavy metal elements such as lead, which realizes the safety and environmental protection of the product application field.
