Galvanized Steel Sheet & Plates, are intended for use where greater corrosion protection is required without painting. A lower cost alternative to stainless steel, galvanized sheet and plates have a rust free protection for up to 30 years, while maintaining strength with a durable surface coating. Our company stocks many sizes in precut sizes, full mill sizes or we can hot dip virtually any size and quantity required for your welding or construction project.
Galvanized steel Sheet coil has a light weight, beautiful and good anti-corrosion performance, can be directly processed. Is mainly used in construction, shipbuilding, automobile manufacturing, machinery manufacturing, furniture home appliance industry, electrical and automation industry. Efficient construction, save energy and protectenvironment, prevent pollution etc.
