Galvanized Steel

  • This is a process of zinc coating
  • Base can be a Carbon steel or Alloy steel
  • Economical choice

 

Stainless Steel

  • SS Sheets comes with oxide layer for protection
  • This material comes in austenitic, Ferritic, Martensitic, Duplex and Precipitation-Hardening
  • Available in a range of grades, 200 series is cheaper compared to 300 and 400 series
