The materials 201#, 202#,304#,430#,316L# are up to standard of GB, ROHS, SVCH etc. Quality is not only the foundation of enterprise but also an important value form of product. We comply with technological process strictly, to ensure the inside welding line is flat, without obvious groove or pimpling, while outside welding line is no black line and clear hand feeling. For the surface, we focus on bright and clean, do not accept the defect of blisters, decrustation, pressure points and liner scratches. Our pipes are attractive and durable, that's the reason why we are the preferred supplier of Furniture, Handles,Sanitary Ware, and Medical Devices. We also accept the order of random length and other material's stainless steel pipes.
Innovative and enter prising spirit is the eternal development power of an enterprise. Since we encourage innovation and ceaseless development, we shall continuously developed new products for market demand and enhance core competitiveness on the basis of improving existing products.
We are base on integrity, let us make progress together and looking forward to cooperate with you!
