Hot-dip galvanizing 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. -

Accoring to the composition, it can be divided into Cr series (400 series),Cr-Ni series (300 series), Cr-Mn-Ni (200 series), heat-resistant chromium alloy steel ( 500 series) and precipitation hardening system (600 series).
201: poor corrosion resistance, widely used as a cheap substitute for 300 series in China.
304: it is the most commonly used. products such as :corrosion-resistant containers, tableware,
furniture, railings, medical equipment.
316: the second most widely used steel type is mainly used in the food industry,clocks and jewelry,
pharmaceutical industry and surgical equipment.
430: Ferritic stainless steel, for decoration, for example for car accessories. Good moldability, but poor
temperature resistance and corrosion resistance.

Custom s235jr s275jr s335jr cold rolled carbon steel coil mild steel carbon coil steel coil manufacturer
It is often used in the steel industry and is distinguished from hot-rolled coils. It refers to the steel strip directly rolled into a certain thickness by a roll and rolled into a whole coil by a winder at normal temperature. Compared with hot rolled coil, the surface of cold rolled coil is bright and high finish, but it will produce more internal stress, and it is often annealed after cold rolling. Due to the absence of heating in the production process, there are no defects such as pitting and oxide sheet that often occur in hot rolling, and the surface quality is good and the finish is high. Moreover, the dimensional accuracy of cold-rolled products is high, and the performance and organization of products can meet some special requirements, such as electromagnetic properties and deep drawing properties.

Prime quality SS400 Astm A570 4mm 1250mm 1500mm low carbon high quality pickled hrc hot rolled steel coil for fabrication
Hot Rolled Steel Coil (HRC) use continuous casting slabs or blooming slabs as raw materials. They are heated by a walking heating furnace and descaled with high-pressure water before entering the rough rolling mill. The rough rolled material is cut into the head and tail and then enters the finishing mill. The computer is implemented. Controlled rolling, after final rolling, it undergoes laminar cooling (computer controlled cooling rate) and coiling machine to form straight coils.

ASTM a36 grade 12mm 16mm MS carbon iron coil hot rolled steel coils S235jr Carbon steel coil
Carbon Steel coil
Rolling is divided into cold-rolled and hot-rolled steel sheets, and the recrystallization temperature is the distinguishing point. The hot-rolled sheet has poor toughness and surface smoothness, and the price is low, while the cold-rolled sheet has good stretchability and toughness, but the price is more expensive. The cold-rolled sheet is cold-rolled, and the
surface has no oxide skin and is of good quality. The hot-rolled sheet is processed by hot rolling, and the surface has an oxide scale, and the thickness of the sheet is poor. -
DX51D Z80 Z180 Z610 Hot Dipped Galvanized Steel Coil/Sheet/Strip for Ventilating Duct
galvanized coils, the thin steel plate is immersed in the molten zinc bath to make the surface of the zinc thin steel plate adhered. It is mainly produced by continuous galvanizing process, that is, the coiled steel sheet is continuously immersed in a galvanizing tank with molten zinc to make galvanized steel sheet; alloyed galvanized steel sheet. This kind of steel plate is also manufactured by hot dipping method, but immediately after leaving the tank, it is heated to about 500°C to form an alloy film of zinc and iron. This galvanized coil has good paint adhesion and weldability.
