Stainless Steel Rectangular Tubing

304 Stainless Steel Rectangular Tubing

304 stainless steel is a highly versatile and inexpensive stainless steel exhibiting great strength and corrosion resistance. 304L stainless steel contains less carbon than the standard 304 alloy, making it easier to form and weld but lower in strength. 304 stainless steel rectangular tube has excellent high and cold temperature working properties, making it ideal for outdoor installations and other harsh environments where carbon rectangular steel tubing would quickly fail.

316 Stainless Steel Rectangular Tubing

316 stainless steel contains a higher proportion of molybdenum, which increases its corrosion and temperature resistance. These attributes make 316 Stainless Steel Rectangular Tubing particularly well-suited for harsh and corrosive outdoor applications. As a low-carbon version of 316 stainless steel, 316L stainless steel has a slightly lower tensile strength and yield strength but is more amenable to the welding process.

Polished Stainless Steel Rectangular Tubing

Stainless Steel Rectangular tubes were designed to achieve a bright, reflective finish and an easy-to-maintain surface, it is achieved by thoroughly removing the surface scale of the hot-rolled annealed and pickled surface, then grinding out the weld joint and using non-metal abrasives to achieve an Ra 32 polished surface. With stainless steel tubing and piping, polishing the internal and external surfaces is critical for eliminating small cracks or crevices in which bacteria or other contaminants could accumulate. Having a smooth, polished surface also extends the surface life of stainless steel tubing and piping. The requested finishing standard will generally determine the types of abrasives used and the number of steps required to complete the polishing process. Surface tester is used to measure roughness and ensure that the finish met the specifications.

Rectangular Tubing Applications

While thicker-walled stainless steel pipes are stronger and better suited for high-load structural applications, stainless steel tubes are perfect for decorative or architectural applications that benefit from a lighter weight and less expensive solution.

  • Architectural structuring
  • Handrail, Rails and ladders
  • Furniture
  • Food processing equipment
  • Marine applications
  • Automotive components
  • Fluid handling systems
