With development of past 20 years, Rainbow Steel became into an integrated iron and steel enterprise and we are also the biggest electrical transmission steel tower factory in China. Mainly exporting products are galvanized steel pipes, jobs of steel structures or frame works, galvanized iron angle bar, flat bar, iron channels and beams, steel profiles, steel towers and steel tube post for electrical transmission powder pole, substation structures, and all other steel jobs which will need further processing such as galvanizing, powder coating, painting, slitting, welding, punching and drilling and straightness adjusting, etc.... With our professional work on exporting and super product quality, we won all customers’ recognition and good reputation. Our aim is highest quality, competitive price, and best service to satisfy our customers. We will keep on innovating products and updating our service.
Welcome all the friends to visit us in Tianjin. Corporate with us, “WIN-WIN” you and me.
Welded steel pipes with hot dip coating or electric-galvanized coating on the surface of galvanized steel pipes. Galvanizing can increase the corrosion resistance of steel pipes and prolong their service life. Galvanized pipes are widely used, not only as pipelines for water, gas, oil and other general low-pressure fluids, but also as oil well pipes and oil pipelines in the petroleum industry, especially in offshore oil fields, oil heaters, condensation coolers, tubes for coal distillation and washing oil exchanges in chemical coking equipment, and tubes for trestle pipe piles and support frames in mine tunnels.
Different apply solution designed with different steel tubes, usually in square and round forms. As an important part of steel instruction, the square or round tubes require high straightness and distortion. We strictly control the dimension accuracy and surface flatness of hot rolled coils from the material link, and then cut and twist the coil twice after the production of steel tube is completed. Straightening to ensure that our products fully meet the requirements of the drawings.
Pipe material is Q355 or S355. Hot galvanizing or pre-galvanizing can be selected according to customer’s requirements. The average thickness of hot galvanized zinc layer reaches 80 microns. We provide customized packaging and overall packing plan for customers, greatly improving the safety of pipes and unloading speed.
