Stainless Steel Welded Tube ASTM554

304L, SS316, or SS316L stainless steel. These materials can be distinguished by their nickel contents. The higher the nickel content is, the greater rust-resistant ability the stainless steel tube will have. Generally speaking, the nickel content of SS201 is around 1-2 percent, SS301 being 5-6 percent, SS304 being 8-9 percent, SS316 being 10-12 percent.

10. Packing: Each individual pipe is put in a plastic bag. Then the tubes will be packed together from outside. Customized packing is also available.

Our stainless steel welded tube can be further processed into various other products, such as railing system parts and accessories. So far it has been widely used in manufacturing of balcony rails, anti-theft window screen, balusters, kitchen and hotel supplies, garden fences, guardrails, and more.

All the raw materials have been selected from TISCO, BAO STEEL and SOUTHWES. Thanks to these suppliers’ high quality material, we are able to produce qualified and durable welded tubes with good expanding and bending capacity.

With 15 years’ production experience in making stainless steel pipes, our company also set up branch factories engaged in making stair rails and many other characteristic stainless steel accessories. Putting together the two factories working experience, we are confident in making better handrails and stainless steel products.
