1. Galvanized iron steel coil simple introduction
It is produced by advanced production line which employs radiation hot-dipped galvanizing
process.The production line uses advanced non-oxidation burner and surface finishing and
leveling process, as well as process which ensure the product in conformity with customers'
requirements on mechanical properties and surface quality
2. Galvanized iron steel coil main usage
Widely used in home appliances, kitchen utensils, handicrafts, construction formwork, granary,
revealed rain, chimneys, roof tile, fire shutter doors, construction industry, as raw material for
the production of corrugated panels, fencing products, drywall panel profiles, ventilation systems.
3. Galvanized iron steel coil features & properties
It uses quality full hard rolled steel sheet from large national steel group as base material, which
has good weather-proof property and adhesiveness, and the product can meet the application
requirements in buildings, electrical appliances, floor decks, civil galvanization, etc

5. Galvanized iron steel coil technical process
After cleaning and acid pickling, the steel coil is submerged in melted zinc, a chemical reaction
permanently bonds the zinc. The zinc actually permanently becomes a part of it and successive
layers are a mixture of zinc and iron
