Name Galvanized roof Standard AiSi, ASTM, bs, DIN, GB, JIS Grade SGCC/CGCC/TDC51DZM/TDC52DTS350GD/TS550GD/DX51D+Z Type Steel Plate Technique Hot Rolled Surface Treatment Galvanized Application Boiler Plate Special Use High-strength Steel Plate Width 600-1100mm Length 2-5M or as required Characteristics�¯�¼?Weather proof; heating insulation; fireproof; anti-rust; sound insulation; long life span: more than 20 years. Corrosion Resistance: the aluzinc coating surface protects the base steel not only by providing barrier to corrosion elements, but also by the sacrificial nature of the coating. 01. SMOOTHNESS No composite indentation, no residual stress, no deformation after shearing. 02. DECORATIVE You can choose a realistic material and aesthetic wood grain, stone coating. Patterns and colors can be customized according to customer requirements. 03. DURABILITY Surface paint, high gloss retention, good color stability, minimal change in chromatic aberration, and long service time. 04. STABILITY The change of wind pressure, humidity and temperature will not cause bending, deformation and expansion. It has strong bending and flexural resistance.
