Coated Steel Sheet
Coated steel sheets provide long-term protection for the original sheet due to the sacrificial corrosion action of the Zn or Zn-Al alloy coating layer. In addition, its corrosion resistance and lustre are further enhanced by surface post-treatment.
01
300,000 tonnes per year production capacity
SeAH Coated Metal manufactures both hot-dip galvanised steel sheets (GI) and hot-dip Al-Zn alloy-coated steel sheets through the latest continuous galvanising line (CGL) facilities with dual pots
02
Optimal product range
The excellent corrosion resistance of hot-dip galvanised steel sheets (GI) is secured by a zinc coating on the surface of the steel sheet. SeAH Coated Metal also manufactures hot-dip Al-Zn alloy-coated steel sheets with 3 to 6 times better corrosion resistance than GI, providing customers with an optimal choice.
03
Adaptable and prompt customer response
Products of various dimensions are supplied to meet the needs of customers at the right time and are applied in a wide range of fields, such as building materials, home appliances, industrial equipment, and materials.
