Is hot dipped galvanized better?
The thicker zinc coating produced by hot dip galvanization offers improved rust and corrosion protection versus
pre-galvanization. This is an important quality in a temporary fence panel, as it is most often used outdoors and
exposed to snow, ice, rain, and salt.
How long do galvanised roofing sheets last?
Metal roofing sheets have a considerably long lifespan and, although manufacturers will often state an expected
lifespan of 10 – 15 years, people more than often find that they last much, much, longer with some people reporting
their sheets to still be in good working order after 60 years!
What is purpose of zinc coating on GI sheet?
Because of the sacrificial nature of the zinc, the coating provides corrosion protection for areas of exposed steel
surfaces, such as cutting edges and areas where coating has damaged (scratches, impacts, etc.).
