Stainless Steel Coils are one of the most sought after types of raw material in the construction and manufacturing industries. It was finished steel products such as sheets or strips which has been wound or coiled after rolling. Stainless steel coils are normally classified into hot and cold- rolled types according to current products and international standards, which mainly include 200, 300, 400 series.

With high yield point and tensile strength, stainless steel coils perform resistant elastic deformation and plastic deformation from external force well.
Containing 17% - 22% chromium, stainless steel coils’ surface is covered by an oxide film, preventing further oxidation or corrosion.
With lower carbon and higher nickel contents, stainless steel coils show excellent ductility and tensile-strength, suitable for deep drawing and bending.
Through cold rolling, pickling, annealing and leveling, the flatness, smoothness and brightness of stainless steel coils’ surface are well presented.
2B,a smooth,reflective cold-rolled annealed and pickled finish produced by imparting a final light cold-rolled pass using polished rolls.

| Stainless Steel Coils Packaging And Loading Details | |
|---|---|
| Packaging Details |
According to customer's needs,use wrapping paper.If the transportation period exceeds 10 days or en-counters special climate,we will use waterproof packaging and add plastic film to prevent moisture,water and rust. |
| Loading Details | We use the wooden pallet,triangular wood to fix the coil,and the steel wire rope to hold on the both side.That can prevent from the crush injury effectively. |
