What does GI steel mean?
GI Sheet is “Galvanized Iron” Sheet. Material ms is mild steel and gi is galvanized steel that has been hot dipped .
These days the sheet will likely be made from steel rather than iron.
How long will galvanised steel last?
Between 34 to 170 years. A key benefit of using Hot Dip Galvanizing is its durability. Data shows that galvanizing
can provide between 34 to 170 years of protection for steel.
