GALVANISED CORRUGATED STEEL SHEET
Corrugated roof sheets combine the advantages of organic polymers and steel plates. They offer excellent colorability, formability, and corrosion resistance while maintaining the high strength and processability of steel. These sheets can be easily processed through blanking, bending, deep drawing, and welding.
Since zinc is chemically more active than steel, the galvanized layer provides sacrificial protection to the substrate even if surface defects occur. The hot-dip galvanizing process ensures the mechanical properties of the original workpiece remain intact, offering superior durability against mechanical damage.

Manufacturing Process:
1. HR Coil → 2. HR Slitter → 3. Pickling Line → 4. Cold Rolling Mill → 5. CR Trimming line → 6. Continuous Galvanising line → 7. Cut-to-length & Galvalume Coils → 8. Corrugation Machine → 9. Finished Sheets.
Maintenance Tips:
• Regular cleaning every 3 to 12 months to prevent accumulation of dirt and debris.
• Inspect walls and roofs periodically to ensure no dust accumulation in areas not washed by rain.
