◉ Product Overview
Our galvanized corrugated sheet is manufactured from high-strength hot-dip galvanized steel coil, featuring uniform zinc coating, stable wave shape, and outstanding weather resistance. It effectively solves rust, deformation, and leakage problems in harsh environments, widely used for industrial workshop roofs, warehouse walls, storage buildings, and agricultural facilities.
◉ Key Product Advantages
Superior Corrosion Resistance
Adopt hot-dip galvanizing with coating weight 40-275g/m² (Z40-Z275). The dense zinc layer isolates air and moisture, delaying red rust on cut edges and extending service life over 15 years.
Excellent Formability
Passes T-bend ≤3T & reverse impact test. No coating peeling or cracking during pressing, bending, and punching, adapting to complex on-site molding.
High Structural Strength
Corrugated profile design enhances load-bearing & wind resistance. Resists heavy rain, snow, and typhoons to keep building envelope safe.
Easy Installation & Low Maintenance
Light weight & standard dimensions enable fast construction. Nearly maintenance-free to reduce long-term labor costs.
Eco-Friendly & Safe
RoHS compliant, optional chrome-free passivation, meeting green building standards.
