Black Carbon Steel Square Pipe Welded Steel Pipe
carbon tube is used in a variety of high-demand industries, especially for structural and mechanical support. We offer high-quality carbon steel tubing in square, round and rectangular shapes in a wide assortment of widths, wall thicknesses and outside diameter measurements.
There are many good qualities that are making the ASTM 1020 square Tubing high in demand. It is the high tensile strength, rugged construction, corrosion resistance, high durability, flexibility, sturdiness, easy to fit, longevity, withstanding heavy loads and high-temperature atmosphere. Additionally, other attributes like stress corrosion cracking resistance, general corrosion resistance, crevice corrosion resistance and anti-corrosive are offered.
In-house processing capabilities for carbon tube include chamfering, deburring and laser cutting, with just-in-time delivery and available stocking programs for the custom sizes you need. Our base stock includes the following grades, types and thicknesses:
