Corroded, undersized, or failing steel beams replaced safely and efficiently. Structural repair specialists serving Sheffield and South Yorkshire.

Over time, steel beams can deteriorate due to corrosion, water damage, or simply being undersized for the loads they were asked to carry. If you’ve noticed cracking in walls or ceilings, sagging floors, or visible corrosion on exposed steelwork, it may be time to have your existing beams assessed and potentially replaced.

Designed to Build carries out RSJ replacement and structural repair work across Sheffield and South Yorkshire. Our process begins with a thorough structural assessment, followed by commissioning updated structural calculations to determine the correct replacement beam specification. We then install the new beam with full temporary support in place throughout, ensuring the structural integrity of your property is never compromised.

We also carry out structural repair work where full beam replacement isn’t necessary – for example, cleaning and treating corroded steelwork, adding supplementary support beams, or reinforcing bearing points.
