There are three major steel tube types in steel fabrication – regular hollow sections, square hollow section and circular hollow sections. As their name suggests, steel tubes have hollow tubular section in the middle. Steel tube sizes vary depending on their intended application (usually in structural steel).

There are three major types of steel tube – circular, rectangular and square. Steel tube sizes will vary depending on their application.

Circular Hollow Sections

Circular Hollow Sections have hollow tubular cross sections and have much higher resistance to torsion that tapered flange beams. Thickness of the walls are uniform around the entire circle which makes this beams great for use with multi-axis loading applications.

Circular steel tube sizes vary greatly.

Rectangular Hollow Sections

Similar to circular hollow sections however they have rectangular cross sections. They are very popular in many mechanical and structural applications. Their flat surfaces make them prime for use in joining and fabrication.

Rectangular steel tube sizes vary greatly.

Square Hollow Sections

Like their hollow section brothers but with square cross sections, these are used in smaller applications such as columns or posts. However they are unsuitable for beams as their shapes are inherently difficult to bolt into other shapes. They are also known as ‘box sections’.

Square steel tube sizes range vary greatly.
