Product Description

Product Description

 

Galvanization is the process of applying a protective zinc coating to steel, significantly extending its lifespan by preventing rust and corrosion far beyond what paint can achieve. Typically, galvanized steel can resist degradation for 50 years or more before signs of rust appear. This robust material is essential for producing corrosion-resistant nuts, bolts, and nails, and is ideal for outdoor applications where plastic piping lacks the necessary strength. Its versatility makes it a preferred choice for bus stop benches, balconies, verandahs, staircases, walkways, and ladders.
Hot Dipped Galvanized Steel Sheet in Coil (GI)This premium product is created by passing a Full Hard steel sheet, which has already been acid-washed and rolled, through a molten zinc bath. This process applies a protective zinc film to the surface, ensuring superior durability and longevity.
Renowned for its outstanding corrosion resistance, paintability, and workability, hot dipped galvanized steel sheet and galvanized steel coil both benefit from the unique characteristics of zinc. The process and specifications for these products are generally consistent, ensuring reliable and high-quality performance.
