Product Information

Full details

The UKLintels 2550mm External Solid Wall Box Lintel with Toe is designed for professional builders and contractors tasked with structural masonry support in 200-215mm solid walls. Its primary benefit is providing robust, high-performance load-bearing capacity for floor loads and roof trusses while offering a built-in plaster key for seamless finishing. A notable caveat is that its 2550mm length requires careful planning for transport and safe manual handling on-site to prevent bending or injury.

Extended Product Information

FAQs

Is this lintel suitable for cavity walls?

No, this specific model is engineered for solid wall construction (200-215mm).

Can I cut this lintel to size?

Cutting structural steel lintels is generally discouraged as it can compromise the load-bearing rating and protective galvanised coating.

What is the 19:1 load ratio?

It refers to the ratio of the span to the load-bearing capacity, indicating how the lintel performs under specific structural loads.

Does the lintel require painting?

The galvanised finish provides excellent protection on its own, but you can paint it using a suitable metal primer if aesthetics require it.

What is the minimum end bearing required?

A minimum of 150mm of masonry support on each end is standard for this type of lintel.

Troubleshooting

Lintel appears slightly bent

Check if the lintel was stored flat on level ground. If significantly deformed, it must be replaced as it will not meet load-bearing requirements.

Plaster not adhering to the lintel surface

Ensure the plaster key is free from heavy debris or thick grease. Apply a suitable bonding agent or metal primer if the surface has become excessively smooth.

Pros and Cons

Pros

  • Excellent corrosion resistance from galvanised finish
  • High structural load-bearing capacity
  • Built-in plaster key saves time during finishing
  • Suitable for a wide range of loads including roof trusses
  • Consistent and reliable manufacturing quality

Cons

  • Requires proper safety equipment for handling the 2550mm length
  • Specific to 200-215mm wall thicknesses
  • Must be handled carefully to avoid deforming the steel profile

Setup, Compatibility & Care

Installation should always follow structural engineer specifications. Ensure the lintel is supported by at least 150mm of solid masonry on each end. Always use a damp-proof course (DPC) as required by local building regulations to prevent moisture bridging. To maintain the product, avoid using abrasive cleaners or corrosive substances near the steel. If the galvanised coating is accidentally scratched during installation, apply a cold-galvanising spray to the affected area to prevent localized oxidation. Store the lintels flat and off the ground to prevent warping before use.
