Galvanized steel coil, a thin steel plate is immersed in molten zinc liquid, with a layer of zinc thin steel plate attached to the surface. It has been successfully used in industries that have strict requirements on corrosion resistance, durability, strength and appearance. It can be formed or applied in various coating. Galvanized steel coils have good paint adhesion and weldability.
1. Corrosion resistance and anti-rust: The main advantage of galvanized steel coil is its anti-corrosion and anti-rust properties. The iron element in steel is a highly reactive chemical that causes rust easily. But the addition of zinc acts as a protective buffer between the steel and moisture or oxygen. So the zinc layer acts as a barrier against outside attack and sacrifices itself to protect the steel underneath.
2. Lifespan: After galvanizing, the lifespan of GI coils in the working environment is far more than 50 years, and it can last more than 20 years in severe contact with water.
3. Cost: First, the overall cost of galvanizing is lower compared to other coatings. Additionally, galvanized steel coils are delivered ready for application. It requires no additional surface preparation, inspection, painting or coating.
4. Durability and reliability: Galvanized steel usually uses hot-rolled or cold-rolled steel coils as the base material. The steel has high strength and the galvanized layer is strong and durable.
Application areas
