EGI Electro-galvanized Steel

EGI Electro-galvanized Steel
Electro-galvanized steel sheets are produced by applying zinc to the surface of hot-rolled or cold-rolled base material by electroplating.  The surface is smooth and attractive, and the product has the same formability and weldability as the base material. Corrosion resistance, lubricity, and other properties are improved by applying various conversion treatments to the surface to meet diverse customer needs.





Usage : Auto bodies, bus bodies, refrigerator parts, air-conditioner parts, oil filter body, steel drums and etc. (good for any painting applicable)

Hot-Rolled

Hot-Rolled
HRC . The steel is shaped as a slab (Slab) through hot rolling process, reduce the temperature of 1100-1250 °C With a roller or rolling big rig rolled into thin sheets with a thickness as required. Then cooled by the coolant. It enters the coil . When producing finished steel can be gray , black , and in a roll (coil) called ” hot rolled coils (hot-rolled coil)” or ” rolling black (black coil)”. For easy storage. Transportation . And ease of navigation to be processed into other products next.






Usage  : (SPHC, SS400) Normal forming, stamping, oil seal, gasket sheet, structure, sprockets, chains,bike parts and many more..(P/O or Pickled & Oiled) Forming, stamping, auto parts and etc.

Cold Rolled

Cold Rolled
Cold Rolling is a process by which the sheet metal or strip stock is introduced between rollers and then compressed and squeezed. The amount of strain introduced determines the hardness and other material properties of the finished product.


Usage  : (SPCC-SD)Refrigerator parts, bodies, furniture, auto parts,  boiler, steel drums & etc. (SPCEN)  Deeper drawing/ forming  properties than SPCC-SD

Hot Dip Galvanized Steel (GI)


Hot Dip Galvanized Steel (GI)
Hot-Dip Galvanizing or HDG is a process in which zinc bonds to steel at the molecular level to produce a four-layer corrosion-resistant finish.  The first three layers are zinc-iron alloy layers that are actually harder than the base steel. The fourth or top layer is pure zinc.






Usage : Refrigerator & chiller parts, air-conditioner parts, ducting, gutter, roof sheet, topping and etc.
