The raw material of cold rolled steel coil is high quality hot rolled product, and after pickling continuous rolling, degreasing, annealing, skin pass, slitting and cut to length line etc.
Firstly, the hot rolled coils are used as raw mateirals, the oxide film was removed with pickling and annealing. During this process, the hardness of the hot rolled coils are lowered, and the performance of steel is improved. There are Two kinds of annealing treatment, one is Bell-type annealing furnace producing bright steel coils, the other is Continuous Annealing furnace producing black steel coils.
1)Material: Ordinary Carbon Steel - Q195, SPCC, DC01, ST12, can be applied in cold-roll forming, such as civil electronics, furing channel, steel pipes, freezing tools. But cannot be used in punching pressing.
2)Material: Punching Pressing Grade Steel - O8AL, SPCD, DC03 / 04, ST13 / 14, can be applied in punching pressing. for complex steel structure, home appliance, automobile and traffic communications and etc.
3) Material: Superior Punching Pressing Grade Steel -SPCE, SPCEN, DC05 / 06, ST15 / 16, along with the excellent features of good punch -pressing, The product is widely used in container holder equipments, steel door and window manufacturing.
|COIL INNNER DIAMETER||508mm or 610mm|
All goods will be inspected after finishing manufacture, a series of tests will be carried out, such as
1) Thickness test ;
2) Width test;
3) Hardness test,
4) Tensile Yield Strength test.
We ensure that all products confirm to the requirements of the order and relevant international standards.
The packing of coils consists of anti-damp paper, PVC film, hardboard paper, steel box, strapped with steel strips, fitted with locks and edge protectors and guarantees the optimal condition of the deliveryed goods.
