The Zinc-coating of the ERW galvanized construction pipes is executed following the same norms with water pipes acc. to DIN 2444, with zinc quality 99,99% and minimum coating thickness 400g/m2 or 56ìm. Hot-dip galvanizing implies 100% zinc coating of the steel pipe, which is a necessary precondition for long product life in industrial applications, greenhouses, road signs, awnings and other uses.
