Structural Tubing, especially rectangular sections, are commonly used in welded steel frames where members experience loading in multiple directions. Square and circular HSS are very efficient shapes for this multiple-axis loading as they have uniform geometry along two or more cross-sectional axes, and thus uniform strength characteristics.

NOTE:The more universal terms Hollow Structural Sectionand HSSare used in this publication to designate rectangular, square and round structural steel tubing. These terms replace structural tubingand pipe, which had been used Pipe and Tube Properties - Benjamin Steel CompanyFor rectangular sections, tolerance calculated for the larger flat dimension applies to smaller flat dimension, but is increased 50% if the ratio of the cross-sectional dimension is 1.5 to 3.0, and 100% if the ratio exceeds 3.0.

Structural-grade rectangular steel tubing provides support to static structures of all types. Totten Tubes supplies rectangular structural steel tubing for bridges, buildings, highways, and other construction applications. Rectangular, Square and Circular Steel Hollow SectionsContents Profile Located at Jamshedpur, Tata Steel Ltd. was established in 1907 and was the first Integrated Steel Plant in India. It commenced its operations in 1911, with a capacity of 1,00,000 tonnes per annum of ingots and expanded to a million tonnes per annum of saleable steel by the mid fifties.
