Which is better GI or SS?
Which is Stronger: Galvanized or Stainless Steel? When compared at similar thicknesses and forms, stainless
steel is always stronger than galvanized steel. An effective way to compare this is by looking at the tensile
strength of each material. Tensile strength is the resistance of a material to breaking under tension.
Can galvanised steel rust?
Galvanized steel takes a long time to rust, but it will eventually rust. This type is carbon steel that has been g
alvanized or coated with a thin layer of zinc. The zinc acts as a barrier preventing oxygen and water from
reaching the steel, providing advanced corrosion protection.
