Our coloured corrugated roofing sheets are engineered using Al-Zn alloy with advanced coating technology as per EN 10346, ASTM A792, and JIS G 3321 standards. These colour coated roofing sheets are available in thickness ranges from 0.25-1.50 mm and widths up to 1500 mm, they feature 70-150 GSM coating, 3-10 micron primer, and RMP/SMP/SDP/PVDF paint systems. With yield strength up to 220-550 MPa, tensile strength up to 300-560 MPa, and elongation of 16-22%, these corrugated sheets provide excellent durability, corrosion resistance, and structural performance for roofing applications.
Layers of Protection in Coloured Corrugated Roofing Sheet
Our colour corrugated roofing sheets feature a 10 layers protection system designed for superior durability and corrosion resistance. The structure includes a top coat, primer, chemical coating, aluminium-zinc coating, CR steel core, back coat, and guard film, ensuring long service life, weather protection, color retention, and enhanced structural performance.
Advantages of Our Colour Coated Corrugated Roofing Sheet
- Strong corrugated design provides better strength and load-bearing performance.
- These corrugated colour sheet resists deformation and bending.
- Provides enhanced resistance to snow and rain loads.
