What are box sections?

Steel box sections are hollow steel sections, sold in either squares or rectangles, which are commonly used for:

  • Welded steel frames
  • Strong, semi-permanent structures
  • Fences
  • Trailers

In essence, any structure which experiences loading in multiple directions is an ideal candidate for being created with steel box sections. Square sections are particularly effective in projects where multi-axial loading is required, as their uniform geometry provides uniform strength characteristics.

Although i-beams are generally the most effective choice where beams are required, box sections may also be used in place of these. If you are unsure about which is the most effective choice, our specialist team will be able to help you make the right decision for your project.

Additionally, square and rectangular box sections can easily be cut, drilled and welded if you need to adjust the sizing or affix sections together.

The strength and versatility of steel box sections ensures a long-lasting product which can be used for almost any project. And as they’re widely-recycled, you will have no problem recycling any which you no longer use.
