Structural Work: RSJs, Knock-Throughs, and Safety Basics

5 December 2025 • 6 min read • by manmeetksevices

What is an RSJ?

RSJ is a common term for a steel beam used to support loads when walls are altered.

Why safety and design matter

Structural work should be:

  • Designed by a qualified professional
  • Installed using safe methods and temporary supports
  • Checked/inspected where required

Common questions

  • Can we remove a wall completely?
  • Where will the beam sit?
  • How will the finish be made good?
