We always do our Best!
Why you choose us as your best choice?
- Our quality is the top five in China. Raw material is mainly from some famous refinery steel mills, such as BAO STEEL, Tianjin, and Chengdu etc, which are the best and largest raw material manufacturers in China.
- we have been through ISO9001:2008 international quality system certification.
- Warranty period for our honed tubes and chrome bars is 2 years. For some special or important customers, the period is 5 years.
- All the orders, records of production and inspection would be kept for 5 years
- High Precision:
Honed tube (Roughness of tube is 0.2μm and straightness is less than 0.15/1000), piston rod (Plating thickness is 10-100 micron. Surface roughness is 0.2μm and straightness is also less than 0.15/1000)
Product details are completely according to International Standard, chrome rod and honed tube must be cut flatly, and no chrome marks on the surface of rod. (Most of domestic mills don’t do this in order to reduce cost)
- Delivery time is very fast. The average delivery time is 5-30 days after confirming the orders.
- Package:banding with steel strips, braiding parcel at outside
