Rectangular Hollow Sections FAQs

What is the difference between a rectangular hollow section and a rectangular electric resistance welded tube?

Rectangular hollow section is generally used for structural and load-bearing steelwork, while rectangular electric resistance welded tube is often used for lighter fabrication, frames, and general tube applications.

When do you choose a rectangular hollow section vs a square hollow section?

Choose a rectangular hollow section when you need more support in one direction, such as for frames, supports, or wider load paths. Choose a square hollow section when equal dimensions and balanced strength are needed on all sides.

Can RHS steel be used outdoors?

RHS steel can be used outdoors, but it should usually be protected with a suitable finish, coating, paint system, or galvanising depending on the environment and exposure level.

Are rectangular hollow sections suitable for welding?

Yes. RHS steel is commonly used in welded fabrication because the flat faces and consistent profile make it easier to align, weld, and assemble into frames or support structures.
