pipe products, such as ERW steel pipe, hot-dipped galvanized steel pipe, oil casing pipe,SSAW steel pipe, square steel pipe
and steel-plasticcomplex steel pipe.
Besides headquartering in Tianjin, currently we have 11 subsidiariesand branches in Tangshan, Handan,and Shanxi. There
are totally 9000 employees,in addition 64 ERW steel pipe production lines, 42 hot-dipped galvanized steelpipe production

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.
