Ltd was founded in July 1, 2000, with headquarters located at the largest weld pipe production base in China - Daqiuzhuang Village, Tianjin city and is a large-scale steel pipe manufacturing enterprise producing many kinds of pipe products, such as ERW steel pipe, hot-dip galvanized steel pipe, oil casing pipe, SSAW steel pipe, square/rectangular steel pipe, and steel-plastic complex steel pipe.

 

Our Advantages

Why choose us?

 

1-As we all know, the burr is one of the common phenomena occurring in metal cutting. Our company has professional pipe cutting machines for deburring. The saw blade is replaced on a regular basis, in order to make the better square cutting effect. Specifically

We adopts square cut (fast cutting) to make a pipe end treatment, no burrs, clean end

As a result of blunt edge treatment, round steel pipe looks like much thicker as per your specific requirements.

We have advanced equipment and specific devices for an effective treatment of late processing of pipes.

 

2-We keep a large stock of products and the steel pipes have fine workmanship without joints. As steel pipes adopt transverse welding method, the surface of products is smooth and the zinc coating is well-distributed. Steel pipes through this processing boast the property of strong weight capacity to serve huge projects. In the process of production, our workers are meticulous about details of steel pipes. Pipes with joints or scratching surface will be picked out among premium products to ensure the quality. Our processing methods as well as specialized skill make the difference in the fierce competition market.
