  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                                                                 Diameter Test                                  Wall Thickness Test                          Length Test   Tips: The third party inspection such as SGS, BV, RoHS, CE are acceptable.   Part 3 Why us                                                                        Part 4 Packing and Loading                                                  Part 5 Contact us
