  Part 1. Product Show                                                         A. Black annealed steel pipe: It is made from cold rolled black annealed steel strips, formed after electrical 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. Bright annealed 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.   D. Galvanized Steel Pipe: It is made from hot dipped galvanized steel strips, or the steel pipe hot dipped galvanized after erw welding.   Galvanized Steel Pipes are with good performance on the anti rust, it is widely used as the structure of outdoor constructions. such as the frame of ads board, electrical tubing, scaffolding, greenhouse and so on.   Part 2 Inspection Process                                                                 Diameter Test                                  Wall Thickness Test                          Length Test   Part 3 Why us                                                                        Part 4 Packing and Loading                                                Part 5 Contact us
