Square Ornamental & Structural Tubing
Hot Rolled Square Ornamental & Structural Tubing
Structural Tubing has a wide range of sizes. It has become a most important basic section for structural applications because of its adaptability to such varied uses.
Structural tubing is an efficient structural member with many inherent advantages, including strength and lightness. In torsion it is capable of carrying a greater load than any other structural member of equal weight.
Structural Steel Tubing is made from flat rolled basic oxygen steel, which is formed into a tubular shape and then welded by the electric resistance process. In this continuous welding process there is no loss of properties, and no irregularity that may be observed in the structure. Over the years, tests and service have demonstrated that the tube weld is as strong as the base metal.
The permissible variation for straightness shall be 1/8” times the number of feet of the total length divided by 5.
Squareness of Sides
Adjacent sides may deviate from 90º by a tolerance of plus or minus 2º maximum.
Radius of Corners
The radius of the outside corner of the section shall not exceed three times the specified wall thickness
