Galvanized Steel Sheet & Coil
Galvanized sheet has excellent bare corrosion resistance due to its high-quality zinc layer and passivation film characteristics. At room temperature, zinc remains unchanged in a dry environment. In the humid environment, the blood on the surface of zinc forms a very dense Zinc carbonate film, which can protect the interior of zinc from corrosion. Due to the properties of zinc, zinc is plated on the surface of the steel plate to prevent corrosion.

Applications of Galvanized Steel Sheet
Galvanized steel coil can be widely used in different applications after further processing, including:
1. Construction
They are often used as roofing, interior and exterior wall panels, the surface sheet of the balcony, ceiling, partitioning walls, windows and doors, gutter, barn, sound insulation wall, etc.
2. Home Appliances
GI coil is widely applied to home appliances, such as the base of washing machines, water heaters, refrigerators, microwave ovens, etc.
3. Transportation
It is mainly used as decorative panels of cars, decks of trains or ships, containers, road signs, etc.
4. Furniture
such as wardrobe, locker, radiator, lampshade, table, bed, bookcase, shelf, etc.
5. Other Uses
such as post and telecommunication cable, highway guardrail, billboards, etc.
Packaging of Galvanized Sheets
Generally, the galvanized iron sheet is lined with kraft paper and moist proof (plastic) film, and then packaged with iron sheets outside. Then it will be strapped on the bracket firmly to prevent friction.
