Hot-dip galvanizing or HDG is a process in which zinc bonds to steel at molecular level to produce a four-layer corrosion-resistant finishFirst three layers are zinc-iron alloy layers that are actually harder than the base steelFourth or top layer is pure zincHot-dip galvalume steel sheet (GL) is substrated on cold-rolled steel (CRC) in various strength and specificationsCoating composition is 55% aluminum in weight ratio, 43.4% zinc and 1.5% silicone with excellent corrosion and heat resistance performanceHot-dip aluminum-zinc alloy-coated steel technology is successfully developed from hot-dip aluminum and hot-dip galvanized processing, provided with long-term corrosion resistance and heat anti-oxidation resistance of aluminum and galvanic behavior effect of zinc, exerted their characteristics mostMakes incision or scratch difficult to be corrodedPPGI is prepainted galvanized steel, also known as precoated steel, coil-coated steel, color-coated steelGalvanized steel sheet in coil form is cleaned, pre-treated, applied with various layers of organic coatings which can be paints, vinyl dispersions or laminatesCoatings are applied in a continuous process known as coil coatingSteel thus produced in this process is a pre-painted, prefinished ready to use materialPPGI is material which uses galvanized steel as the basic substrate metalCould be other substrates such as aluminum, galvalume and stainless steelEach part of this set can be sold separately: SGCC, CGCC and DX51D+Z

our prodcuts have been exported to many countries and our customers feedback our products are good market .they are very intesed in our products quality.
