Product Description
Our Hot Dipped Galvanized Coil is crafted for industries that demand long-lasting performance under tough conditions. Produced with a cold-rolled steel base, each coil undergoes a molten zinc bath, ensuring complete surface coverage. The result is a brilliant silver-gray appearance that feels smooth to the touch and resists scratches.
When uncoiled, the sheets emit a crisp metallic sound—an auditory confirmation of their density and strength. This combination of tactile smoothness and robust structure gives buyers confidence that the material will withstand decades of exposure without losing its protective qualities.
Ideal for roofing, siding, HVAC ducts, or automobile body panels, these coils reduce the need for frequent maintenance and painting, ultimately lowering lifecycle costs for end users.

Substrate Type
1. Hot-dip galvanized color-coated steel sheet (pre-coated galvanized steel sheet). The product of coating the steel sheet with an organic coating is a hot-dip galvanized color-coated sheet. In addition to the protective effect of zinc, it also has an anti-rust effect and a longer service life than the galvanized sheet;
2. Hot-dip aluminum-zinc color-coated sheet (color-coated aluminum steel sheet) color-coated substrate (55% AI-Zn and 5% AI-Zn);
3. Electro-galvanized color-coated sheets use electro-galvanized sheets as the base material, and are coated with organic coatings and baked to become electro-galvanized color-coated sheets. It is mainly used for home appliances, furniture and other decorative items.
Color coating types: Standard polyester, matte polyester, decorative print.
Coating Type
-
Polyester (PE)：Excellent adhesion, various colors, wide range of molding and outdoor durability, moderate chemical resistance, low cost
-
Silicon modified polyester(SMP): Good abrasion resistance, heat resistance, exterior durability, and powder resistance; average gloss retention and flexibility; medium cost.
-
High Durability Polyester(HDP): Excellent color retention and UV resistance, excellent outdoor durability and chalking resistance, good paint film adhesion, and moderate cost performance.
-
Polyvinylidene Fluoride(PVDF): Excellent color retention, UV resistance, durability, anti-chalk and solvent resistance, good formability, good stain resistance, limited colors and higher cost.
