Galvanized steel coils as raw material can be cut and formed into various types of metal sheets, among which galvanized roofing sheets are one of the most popular and high-quality building materials, which are widely used for roofing buildings in various climatic environments.
Requirements for Galvanized Steel Coil for Roofing
The most important things for roofing material are corrosion resistance, high strength, good toughness, windproofness, and waterproofness. Galvanized steel coil combines the advantages of steel and zinc with good corrosion resistance and processability. The roofing material made of galvanized steel coil can provide good protection for the building as well as the appearance of the effect.
- Corrosion protection: The thickness of the zinc layer on the galvanized steel surface can be selected according to the application environment, from z30-z350g, and is resistant to rain, sun, oxygen, sand, and other acids and alkalis.
- Strength: Galvanized steel is bent and processed with corrugated, trapezoidal, c-type, W-type, and other surface structures. These structures have good load-bearing capacity and can withstand wind pressure, snow, etc.
- Waterproof: The corrugated effect is good for drainage. In addition, galvanized steel has a different seam design to avoid rainwater infiltration from the gap.
- Anti-slip: Galvanized steel coils are tough and can be stamped and perforated, and some galvanized roofing sheets with stamped patterns on the surface can improve anti-slip properties.
- Acoustic and thermal insulation: galvanized steel panels can be made into sandwich panels, increasing the sound and thermal insulation effect of roofing materials.
- Easy to install and maintain: Galvanized rolls are processed into roofing materials that are relatively light in weight, making them easy to install and transport.
Types of Galvanized Steel Coils for Roofing
What types of galvanized steel coils are available for roofing? Depending on the climatic conditions of the building, the recommended types of galvanized steel are hot-dip galvanized coils, aluminum-zinc alloy coils, color-coated coils, and many more.
Hot-dip galvanized coils: Hot-dip galvanized coils are available in zinc thicknesses from 60 g/m² to 275 g/m² and are suitable for outdoor buildings in different climatic conditions.
Galvalume coils: Zinc-aluminum alloy coated steel with 55% aluminum and 43% zinc, suitable for roofing buildings in seaside, humid, and polluted areas as well as commercial buildings.
Prepainted steel coils: prepainted galvanized steel coils, prepainted aluminized zinc coils, for residential, commercial, and industrial building facades or roofing materials with high demands on appearance.
