    Hot-dip galvanizing (galvanizing), also known as hot-dip galvanized and zinc: is an effective way of metal corrosion, mainly for various sectors of the metal structure facilities. Is immersed steel rust after about 500 ℃ melted liquid zinc, steel member attached to the surface layer of zinc, which serve the purpose of preservation.
    Hot-dip galvanizing process: Finished pickling - washing - plus help bath - drying - rack - cooling - medicated - cleaning - polishing - hot-dip galvanizing is completed galvanized steel, stainless steel, cast iron and other metal immersion. liquid molten metal or alloy to obtain a coating technology.
    Hot-dip galvanizing is the world's most widely used, best price-performance steel surface treatment method. Hot dip galvanized steel products to reduce erosion life extension, energy and materials played an invaluable and irreplaceable role, but also the national steel plating and foster short-term priority to the development of high value-added products.

Hot-dip galvanized and galvannealed Introduction
    Hot Coil galvanized products fill the gaps, in order to become a low-cost high-quality steel z-type structure supporting the ideal material purlin C steel, steel and so on.
    Cold-rolled sheet steel galvanized product is suitable for high strength cold forming, automotive industry, construction, household appliances, color-coated substrate, transportation and other industries. Surface structure and normal spangle zinc-iron alloy coating.
    For galvanized products, due to the continuous annealing for a short period of heating and cooling, and so are less than the corresponding processing performance of some of the cold-rolled products, but I designed the production process, is fully capable of manufacturing of deep drawing surplus product. Galvannealed coated product has a good performance.


Product Categories
◇Press the substrate Category: cold-rolled, hot-rolled
◇Press the substrate steel Score: Stamping, structure type, high strength type
◇By coating TYPE:GI、GA、GF、GL
◇Press spangle structure: no spangle, small spangle, regular spangle
◇According to whether the finishing point: finishing spangle, non-finishing spangle
◇Divided by the surface treatment: passivation, fingerprint-resistant, phosphate, oiled, passivation coating oil, does not deal with

Common galvanized steel sheet has:
  General merchandise volume (CQ), the structure of galvanized plate (HSLA), stamped galvanized sheet (DQ) deep drawing hot galvanized plate (DDQ), hot galvanized plate bake hardening (BH), dual-phase steel (DP) , TRIP steel (transformation induced plasticity steel) and the like.
The difference between hot-dip galvanized and electro-galvanized sheet
  Hot galvanized plate is hot-rolled galvanized sheet, cold-rolled galvanized sheet is galvanized sheet. From the materials, composed of two galvanized sheet are substantially similar. The difference is that galvanized plate hot galvanized plate is more than thin, better surface quality, process more complex. Some higher the price will.
  From the process, the steel slabs sent from the hot rolling, rolling into a certain thickness of the plate, such as a thickness of about 10mm, if the user surface, the thickness, the mechanical strength of the sheet is no higher requirements, then you can deal with the finished product, such as zinc and the like, direct sale, it is the hot plate. If the board have higher requirements, the rolled sheet before they take cold rolling processing line again, pickling, annealing, rolling and other processes again, get thinner, smooth surface, better mechanical properties of cold-rolled sheet

Galvanized products Applications
    After cold rolling mill rolled strip before and after treatment for degreasing, into the first continuous hot dip galvanizing line is annealed in an annealing furnace, and then into the pot of molten zinc hot-dip galvanizing, and then after finishing or passivation, tension leveling, and the corresponding post-processing the resulting product.
    The company produces galvanized steel is mainly used in household appliances, computer chassis, electrical cabinets, vending machines, automotive parts and painted substrates. 5% aluminum-zinc plated steel suitable for C, Z-beam, air conditioning ducts, windows, door frames, automotive interior parts, painted substrates. 55% aluminum-zinc-plated steel plate for wind-pipe, automotive components, electrical equipment, refrigerators, ovens, coating the substrate, display cabinets, lightweight steel and the like.
