Applicant:

• Advantages: 
•  We use the best raw material, precision cold rolling process, precise slitting process, de-burring of edges and constant hardening and tempering process to assure our material with close tolerance in shape and mechanical properties.
• Each production's process is performed in the company to guarantee best flexibility and strictly quality control.
• We have our owncold rolled facilities, firstrate crud materials purchaed from ISO certificated enterprise to guarantee superior quality.
• All processes are done with our skillful employees and morden facility to assures best performance in surface finishing, flatness and constant of mechanical poperies.
• Each coil before packing has been checked by width, thciness, hardness, straightness, bend-ability and elasticity.
