Hot dip galvanizing is the process of coating pipe and fitting with a layer of zinc alloy in a bath of molten zinc at temperature around 450 °C. As ISO 1461, ASTM A123, and EN10240, the galvanizing process has its own built-in means of quality control because zinc does not react with an unclean steel surface.

Steel pipe schedule is a indicating method represented by ASME B 36.10, and also used in many other standards, marked with Sch. Sch is the abbreviation of schedule, generally appearing in the American steel pipe standard, which is a prefix of a series number. For example, Sch 80, 80 is a pipe number from chart/table ASME B 36.10.

As a rule, welding hot-dip galvanised steel is no different from welding non-galvanised steel. Research has demonstrated that the mechanical properties of steel, whether galvanised or non-galvanised, welded or not welded, are identical. It is necessary to look at the area around the weld. The zinc coating must be removed on either side of the [Hot Item] 1/2"-24" (20mm-610mm) ASTM JIS DIN GB 1.ERW steel pipe/tube 2.Galvanized steel pipe/tube 3.Black hollow section 4.Galvanized hollow section 5.Galvanized steel coil/GI steel coil 6.PPGI coil/prepainted galvanized steel coil 7.GL coil/galvalume steel coil 8.PPGL coil/prepainted galvalume steel coil 9.Corrugated roofing sheet 10.Steel coil/steel plate All Groups Product Catalogs
