Galvanized Steel Powder Coated Color Coated Corrugated Roofing Sheet

Advantages of galvanized corrugated sheets

1.The core advantages of galvanized steel sheets lie in their excellent corrosion resistance, economic practicality and processing flexibility ‌, and they are widely used in construction, automobile manufacturing, home appliances and other fields.

2.The main advantages of ‌galvanized steel sheets are Excellent corrosion resistance: The zinc coating effectively prevents the steel plate from oxidizing and rusting by isolating air and moisture.

3.Moreover, the cathodic protection effect of zinc can delay the corrosion of the base material, and the anti-corrosion life can reach several decades. The zinc coating thickness of hot-dip galvanized steel sheets is usually 50-300g/m², and their corrosion resistance is significantly better than that of ordinary steel sheets.

4.Economical and efficient cost control:The galvanizing process accounts for approximately 50% of the global zinc production, and the unit anti-corrosion cost is only one-third of that of stainless steel, with outstanding cost performance.

5.No additional anti-corrosion treatment is required after construction, reducing maintenance costs.

1.Packaging materials:The packaging of galvanized sheets should be firm and tight to prevent the goods from shifting or being damaged during transportation. Commonly used packaging materials include wooden crates, plastic sheeting, air cushion film and foam, etc.

2.According to the quantity, size and weight of the goods, select appropriate packaging materials and methods to ensure that the goods are not bumped or damaged during transportation.

3.Anti-friction and moisture-proof:galvanized sheets are generally packaged in two ways: galvanized sheets cut to a fixed length and coil galvanized sheets. It is generally packed with iron sheets and lined with moisture-proof paper to prevent friction and moisture. The packaging should be friction-proof and moisture-proof to ensure the packaging is firm.

4.Marking requirements:When packaging and bundling hot-dip galvanized steel grating, plates of the same specification should be neatly stacked together, with the side bearing the label or steel stamp placed on the outside for easy inspection. When using packing straps, ensure that there are packing straps on both sides and on all four sides.
