Galvanized steel strip
Hot-dip galvanizing steel strip is the reaction of molten metal with an iron substrate to produce an alloy layer, thereby combining the substrate and the plating layer. Hot-dip galvanizing is to pickle iron and steel parts first. In order to remove iron oxide on the surface of iron and steel parts, after pickling, it is cleaned in an ammonium chloride or zinc chloride aqueous solution or a mixed solution of ammonium chloride and zinc chloride.And then sent to the hot-dip plating bath. Hot-dip galvanizing has the advantages of uniform coating, strong adhesion and long service life.

Product Show
1.1.1 Substrate Type
1.Hot-dip galvanized color coated steel sheet(prepainted galvanized steel sheet)The product obtained by coating an organic coating on a hot-dip galvanized steel sheet is a hot-dip galvanized color-coated plate. In addition to the protective effect of zinc, the hot-dip galvanized color-coated sheet also protects against rust and has a longer service life than hot-dip galvanized sheet; 2.Hot-dip aluminum-zinc color coated sheet(prepainted galvalume steel sheet)Hot-dip aluminum-zinc steel sheets can also be used as color-coated substrates (55% AI-Zn and 5% AI-Zn); 3.Electroplated zinc color coated sheet The electro-galvanized sheet is used as the substrate, and the product obtained by baking with the organic coating is an electrogalvanized color-coated plate. It has a beautiful appearance and excellent processing properties, and therefore can be mainly used for home appliances, audio, steel furniture, interior decoration, and the like.
1.1.2 Coating Type
Polyester (PE): Good adhesion, rich colors, wide range in formability and outdoor durability, medium chemical resistance, and low cost. Silicon modified polyester(SMP): Good abrasion resistance and heat resistance, as well as good external durability andchalking resistance, gloss retention, general flexibility, and medium cost. High Durability Polyester(HDP): Excellent color retention and anti-ultraviolet performance, excellent outdoor durability and anti-pulverization, good paint film adhesion, rich color, excellent cost performance. Polyvinylidene Fluoride(PVDF): Excellent color retention and UV resistance, excellent outdoor durability and chalking resistance, excellent solvent resistance, good moldability, stain resistance, limited color, and highcost.
Galvanizing steel production line with annual output of 500000 tons,which adopts the most advanced American GBNB and Germany's Siemens electrical control systems. it can produce ZERO zinc spangle, small-zinc spangleand common zinc spangle etc.Thickness from 0.125 mm to 4.5mm, and width from 500 mm to 1250 mm, and zinc coating from 40 - 275 g/m2,surface passivation and oil -coating can be performed. In addition, the company introduces a slitting machine, which can meet the customers' different requirements on the width. And Two roll-formed machines , which can produce wave roofing sheet and Trapezoidal corrugated sheet.

Galvanized Steel strip
Spangle is formed during the hot-dip galvanizing process. The size, brightness, and surface of spangles mainly depend on the composition of zinc layer and the cooling method. According to the size, it includes small spangles, regular spangles, big spangles, and free spangles. They look different, but the spangles almost will not influence the quality of galvanized steel. You can choose according to your preference and purpose.
