Pre Galvanized Steel Pipe
Pre-galvanising, also known as mill galvanising, involves passing steel sheets through molten zinc. After this process, the steel sheet is cut to the desired size and re-rolled. During pre-galvanising, the entire steel sheet is coated with a specific thickness of zinc. For example, pre-galvanised Z275 steel sheets have a zinc layer thickness of 275 grams per square metre.
