Rectangular Hollow Sections

General Information

Rectangular Hollow Sections (RHS) are particularly desirable because of their static and structural properties. Similar to Square Hollow Sections (SHS), RHS are less prone to bending making them more sturdy and thus suitable for a wide variety of applications.

RHS are easily joined by welding and bolting which enables the creation of complex angles. Hence they are commonly used for complex construction work. Engineers can utilise the cavities to their advantage by running wires or support material through the cavity which can further improve the materials weight bearing capacity.

Utilizing Rectangular Hollow Sections can help keep costs to a minimum. The reduced weight of hollow steel products like RHS simplifies transport and installation, thereby reducing expenditures. Additionally any coatings or finishes need only be applied to the outside surface, further reducing costs.

RHS are often used by architects as a design element.

How are Rectangular Hollow Sections manufactured?

RHS are commonly manufactured from a round, hollow feeder tube. To achieve the desired rectangular form, the feeder tube is passed through a die, sometimes in several cycles.

Depending on the desired finish, a hot or cold rolling process is applied. RHS can also be manufactured by directly reshaping a steel sheet and welding the open seam shut. Then in a final step the length of the RHS is adjusted by cutting the material.

Which industries utilise Rectangular Hollow Sections in their manufacture?

The primary industries utilising RHS in their manufacture are listed below:

  • Construction
  • Pipe construction
  • Aircraft engineering
  • Ship construction
  • Engine and plant engineering
  • Automotive industries

What are the benefits of rectangular hollow sections?

RHS have multiple advantages, amongst others:

  • High capacity to withstand stress
  • Multiple varieties available
  • Corrosion-resistance (dependant on surface treatment)
  • Stability
  • Easily manipulation
  • Sustainability/recyclability
  • Visually appealing
