The Highest Quality Laser Welded Stainless Steel Tubing

We Provide Stainless Steel Tubing For The Most Demanding Applications


For over 80 years United Industries’ tubing has been ideal for applications that call for laser welding.

United Industries has been perfecting its laser welding capabilities since 1992. We use a fourth generation laser process that has set the standard for laser welded stainless steel tubing. Laser welds are superior to TIG welds in the following ways: they offer less potential for corrosion in weld area, full finished tube appearance, and superior performance.
