Part 1. Product Show
A. Black annealed steel pipe: It is made from cold rolled black annealed steel strips, formed
afterelectrical resistance welding.
Black annealed steel pipe are widely used as furniture structure, such as desk, table, bed, and other
household shelves. This kind pipe can be bend, painted or powder coated.
B. Hot rolled steel pipe: this is the most common pipe in China, formed from hot rolled steel
strips after erw welding.
Hot rolled erw pipe is widely used as construction and machinery structure, the most widely used material for
this kind pipe is Q235 or Gr.B.
C. Hot galvanized steel pipe: It is made from cold rolled bright annealed steel strips, formed
after electrical resistance welding.
Bright annealed steel pipe is widely used as precision car or auto parts or decorative products. It is with good
surface, which could be chromed and painted. And this pipe could be bent according to requirements.
Part 2 Inspection Process
Tips: The third party inspection such as SGS, BV, RoHS, CE are acceptable.
