Hot Dipped Gi Steel Coil 0.12-0.6mm Z180 Dx51d Gi Zinc Coating Galvanized Steel Coil

Dx51D is a European standard (EN 10346) hot-dip galvanized steel coil. Its base material is low-carbon steel, resulting in a uniform zinc coating. It's suitable for applications in construction, home appliances, and automotive applications.
Zinc coating weight: 40-275g/m² (Z40-Z275). Z80-Z180 is commonly used in construction.
Thickness: 0.12-6.0mm, primarily cold-rolled.
Width: 600-1500mm, customizable.
Applications:
Building structures: Roofs and wall panels (Z120-Z180).
Home appliance manufacturing: Refrigerator and washing machine panels (zero-sparkle cold-rolled steel).
Automotive components: Chassis components (high-zinc hot-rolled steel).
