Hot Dipped Galvanized Steel Coil | Z100-Z275 Zinc Coated for Roofing

Core Advantages

 Scenario-matched zinc coating protection

Our hot dipped galvanized steel coils feature Z100 to Z275 zinc coating weights tailored for roofing applications. Z100 suits low-corrosion inland residential roofs, while Z275 delivers enhanced sacrificial anode protection for coastal and industrial areas, effectively shielding the steel base from moisture and atmospheric corrosion.

 Superior adhesion for roofing fabrication

With strict continuous hot-dip process control, the zinc layer forms a metallurgical bond with the base steel. It withstands roll forming, bending and profiling for roof panels without peeling or cracking, maintaining full protective performance after on-site processing.

 Standardized quality with long service life

Manufactured in compliance with ASTM A653 and EN 10346 standards, the coils offer stable mechanical properties. Z275 grade provides 20–25 years of service life in typical outdoor roofing conditions, cutting long-term maintenance and replacement costs.

 Flexible surface options for diverse designs

Regular, minimized and zero spangle finishes are available. Zero spangle works perfectly for paint-coated roofing systems, while regular spangle fits direct exposed applications, with uniform surface free of missing plating defects.

 Industrial factory roofing

Z180–Z275 high zinc coating grades fit heavy industrial plants, logistics warehouses and other outdoor high-corrosion roofing scenarios. They resist industrial exhaust and acid rain erosion, support a design service life of over 25 years, and significantly reduce maintenance frequency and lifecycle costs.

 Civil & commercial building roofing

Z100–Z180 standard zinc coating variants are widely used for residences, office buildings and shopping malls. With excellent cold roll forming performance, they can be processed into various tile profiles, balancing corrosion protection and procurement cost for most climate regions.

 Agricultural facility roofing

Ideal for livestock farms and greenhouse sheds, they withstand prolonged high humidity and ammonia corrosion. The uniform zinc coating has no bare spots, effectively avoiding local rust perforation during long-term operation.

 Public infrastructure cladding

Used for roofing and wall cladding of stations, stadiums and other public buildings, they feature high surface flatness, consistent appearance, plus superior wind uplift resistance and long-term weather durability.
