To assure reliable corrosion protection, the coating thickness and composition, e.g. the Zn, Fe and Al content in hot-dip galvanized coatings, has to be kept

Welding of Coated Steels ::Total Materia Article

Welding of zinc-coated steel can be done, but specific precautions should be taken. When galvanized steel is arc welded the heat of the welding arc vaporizes the zinc coating in the weld area. This is because the boiling point of zinc is below the melting point of steel. The zinc volatilizes and leaves the base metal adjacent to the weld. electrolytic zinc coated steel - 3mm electrolytic zinc-coated galvanized steel sheet General information galvanized steel coil:Specifications of Galvanized Steel Thickness (mm) 0.12-6.0mm Width (mm) 600-2050mm Coating Weighr (g/m2) 30-600g/m2 Inner Diameter (mm) 508/610mm Surface Structure Regular spangle, Minimal Spangle, Zero Spangle, Big Spangle) Surface Treatment Chromated/Non-chromated Oiled/ Non-oiled, secondary steel in coil, secondary steel in coil Suppliers 1.

ZINC COATINGS - American Galvanizers Association

production is used in zinc coatings to protect steel from corrosion. Because zinc is an infinitely recyclable material, the level of recycling increases each year, and but is only applied to steel sheet, strip, and wire. A coil to coil process, steel sheet from 0.010 to 1.70 inches (0.25 mm to 4.30 mm) thick and up to 72 inches (1,830 mm)
