We can offer accurate Material List for your reference. In our Material List, you can clarify the chemical composition contained in steel pipes such as carbon, silicon, manganese, sulfur, as well as phosphorus. The proportion of these elements is different because of the different  product materials or grades from customers. Apart from essential raw materials, the property of products you purchased is also apparent like tensile strength. You should take this factor into consideration when putting our products into application. Of course, if you want to know more information in the Material List, you can put forward your advice and we will exert great effort to satisfy your demands.

as we have a process of welding when manufacturing, the surfaces of steel pipe may be not flat which can not meet the construction industry standards. In order to produce practical products, flattening weld joint applied to round steel pipes and square steel pipes is crucial to the overall manufacturing process. Our small steel pipes can be inserted in large scale pipes, besides, our steel pipes are equipped with other accessories as it seeks to prevent wires from scratching when threading. In addition to flattening inside or outside weld joints, we can also ensure the surface is glossy with solid structure.
