Rectangular steel pipes and tubes are used in different industrial applications. These are used for accomplishing different purposes. The common areas, where these rectangular pipes and tubes are used are: supermarket racks, container fabrication, auto fabrication, motor cycles, doors and windows, industrial plant structure, bicycles, furnitures etc. There are several parameters for defining the rectangular pipes and tubes.

These parameters are length, width, height, welding gap, radius, diameter etc. According to the nature of the requirements, the size of the rectangular steel pipes and tubes can be altered.

We also provide Stainless Steel Seamless Pipes
