Steel rectangular tube/pipe

Use in structures

Steel rectangular tube/pipe, especially rectangular sections, are commonly used in welded steel frames where members

experience loading in multiple directions. Square and circular HSS have 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.

This makes them good choices for columns. They also have excellent resistance to torsion.

HSS can also be used as beams, although wide flange or I-beam shapes are in many cases a more efficient structural

shape for this application. However, the HSS has superior resistance to lateral torsional buckling.

The flat square surfaces of rectangular HSS can ease construction, and they are sometimes preferred for architectural

aesthetics in exposed structures, although elliptical HSS are becoming more popular in exposed structures for the same aesthetic reasons.

In the recent past, HSS was commonly available in mild steel, such as A500 grade B. Today, HSS is commonly available

in mild steel, A500 grade C. Other steel grades available for HSS are A847 (weathering steel), A1065 (large sections up to

50 inch sq made with SAW process), and recently approved A1085 (higher strength, tighter tolerances than A500).


Steel rectangular tube/pipe is made the same way as pipe. During the manufacturing process flat steel plate is gradually

changed in shape to become round where the edges are presented ready to weld. The edges are then welded together

to form the mother tube. During the manufacturing process the mother tube goes through a series of shaping stands

which form the round HSS (mother tube) into the final square or rectangular shape. Most American manufacturers adhere to

the ASTM A500 or newly adopted ASTM A1085 standards, while Canadian manufacturers follow both ASTM A500 and CSA G40.21.

European hollow sections are generally in accordance with the EN 10210 standard.
