Diverse material, surface treatment options widen steel coil selections

Hot- and cold-rolled, and galvanized steel coils rule supply in China. Makers can customize to meet varying application requirements.


  • Hot- & cold-rolled, galvanized types lead: These three categories combined represent about 70 percent of China’s total supply of steel coils, with color-coated and stainless steel types accounting for the rest. The main applications include the shipbuilding, interior decoration, electric appliance, furniture, transportation, roofing system, machinery, construction, vehicle manufacture and military industries. Most products meet international quality standards such as ASTM A653, AISI, EN 10326, DIN 17162 and JIS G3302.
  • Diverse materials: Makers can choose from a growing range of inputs to meet customer requirements. Q235B, Q345B, SPHC, 510L and Q345A are the main options for hot-rolled steel coils, while SPCC, SPCD, SPCE, DC01 and DC02 are for cold-rolled variants. The 304, 316L, 2205, 310S and 309S are the mainstream stainless steel coils. Suppliers apply zinc coating or polyester or silicon-modified polyester film on the surface to improve weather, corrosion, scratch and dust resistance.
  • Varied surface treatment options: Products undergo treatment for heat and water resistance, and anti-oxidation. Oil mill, 2B, sandblasting, BA, mirror and embossing finishes are also popular. For color coating, most makers can turn out models in RAL1000 to RAL9018. They can customize hues as well.
