Rectangular tube is formed from coil and then ran through a series of dies.lt's welded from the inside to form its shape. Rectangular tubes are generally used for maintenance and structural purposes.
Some examples of square tubing applications would be building construction, railings, and sign posts. They are measured by their outside dimensions and their wall thickness.
square Tube is available in the following metal types:Alloy Steel
Mild Steel Carbon Steel stainless Steel
Rectangular tube has similar uses to SHS and is used for both industrial and construction applications.
We offer rectangular steel tubing in carbon steel, galvanized steel, and stainless steel in both mechanical and structural grades. Our selection of rectangular steel tube sizes includes a wide array, ranging from 3/8" x 1-1/2" up to 12" x 20".
