201 stainless steel square pipe refers to a square-shaped pipe made from 201 stainless steel,which is a low-cost alternative to traditional stainless steel grades such as 304.While not as corrosion-resistant as other stainless steel grades, 201 stainless steel square pipe still offers good resistance to corrosion, making it a popular choice in many applications.
201 Welded Square Tube has inside and outside radius corners, with a protruding interior weld seam.Stainless steel square pipes are hollow, square-shaped metal tubes that are widely used in construction, furniture making, and engineering applications. These ss square pipes provide a durable and aesthetically pleasing solution for many design and structural challenges.
Square 201SS Pipe is available in a range of sizes, typically ranging from 10mm to 100mm in width and thickness.It can be supplied in either a polished or a non-polished finish.
