Our Advantages

a. Extensive production experience: we are specialized in honed tubes, skived tubes, cold drawn pipe, and chrome bar with an experience of 20 years.

b. Complete production facilities: owning cold drawn machine, skived and roller burnished machine, honing machine, precision centerless grinding machine, straightening machine, fine polishing machine, precision lathe, milling and drilling machine, roller press and other advanced equipments. Our technicians will do regular scheduled maintenance on these machines to guarantee them work well.

c. High quality raw material: we mainly choose raw material from big steel factory, such as AN STEEL, TPCO, BAO STEEL, SHA STEEL, which are best and largest raw material manufacturer in China.

d. Strict Physical/Chemical testing procedures: meeting the requirements of the product design and process, providing reliable testing data.

e. Short Delivery time: Usually one container 20 days. We also stock some standard-sized tubes and bars.

f. Safe packing: anti-rust oil be spread on tubes and bars before shipping, plastic caps on tube ends to protect inside surface, each bar be protected with cardboard tube.

Production process

Raw material – annealing for material of 45#, 27SiMn, 25Mn – Acid cleaning – parkerizing & Saponifying – cold drawn – leveling – saw off bad section – stress relieving – leveling –inspection – oiled plated - packing
