Quality control
1. We only buy raw material from famous tube factory, and Checking raw material quality before production.
2. We check the tube ID tolerance, OD tolerance and surface after cold drawn one by one.
Our Advantage
1. We has two factories of 40000 square meters and totally 150 employees to promise the Honed Tubes In Stock best quality control;
2. According to the cylinder pressure and inside diameter size ,different hydraulic cylinder honed tube Would be choosed ;
3. Our motivation is --- customers’ satisfaction smile;
4. Our believing is --- pay attention to every detail;
5. Our wish is ----perfect co-operation.
Our focus on should be to consolidate and enhance the quality and repair of present products, in the meantime constantly establish new products to meet unique customers' requires for Hot Sale 1020 Cold Rolled or Drawn Seamless Steel Pipe. Look forward to the future, we'll focus more on the brand building and promotion. We have complete production equipment and advanced production technology, strict corporate management, and perfect quality service system.
