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 and square steel is crucial to the overall manufacturing process. Our small steel can be inserted in large scale , besides, our steel 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.
Our products all have pretty physical appearance with smooth outside welding. Compared with some other suppliers, we use a flat knife for scraping the weld line.

If the excess part of the welding is polished off in the pipe production process, this will somewhat eliminate part of the stress concentration. In addition, our workers are all skilled in the post treatment of , who all have excellent professional experience for many years.
