Galvanizing refers to the coating of metallic zinc on the surface of steel, and its function is to protect the steel from corrosion. Galvanized steel coil products are widely used in construction, machinery, industry, agriculture and other fields. It is one of the most widely used golden products in the world.
Advantages
- Excellent anti-corrosion, paintability, and processability due to the self-sacrificing characterisiticof zinc.
- Available to select and produce the desired amount of zinc gilded and in particula enables thick zinc layers.
- Classified as either zero spangle or extra smooth depending on wheteher the sheet undergoes skin pass treatment.



Shanghai Zhengshang Industrial Co., Ltd. supplies normal spangle, smooth spangle and no spingle galvanized steel coils. The standard thickness of the coil is 0.20-4.0mm (supports customization), the width can reach 1500mm, and the zinc layer weight is 40-350g /m2, the weight of the steel coil is 5-30 tons per coil. The product has stable quality and good corrosion resistance. It is widely used in home appliance manufacturing and building structure. If you have purchasing requirements, please contact us!
