Product Information

Full details

The UKLintels Extra Heavy-Duty Cavity Wall Lintel is designed for professional builders and contractors tasked with supporting significant masonry, roof, and floor loads in cavity wall construction. Its primary benefit is the combination of superior load-bearing capacity for heavy point loads alongside a lightweight design that improves site handling efficiency. While this product is exceptionally durable due to its galvanized finish, users must ensure that the cavity width matches the specific 150-165mm specification to maintain structural integrity.

Extended Product Information

FAQs

Can this lintel be cut to a shorter length?

Structural steel lintels should generally not be cut as this may compromise their load-bearing rating and warranty. Consult a structural engineer before making any modifications.

Does this lintel require additional insulation?

While the lintel is designed for cavity walls, you should always check local building regulations regarding thermal bridging and ensure insulation is maintained through the cavity as required.

What is the primary material used?

The lintel is manufactured from high-grade structural steel with a galvanized finish for corrosion protection.

Is this suitable for a 120mm cavity?

This specific model is designed for 150-165mm cavities. It is not recommended for a 120mm cavity as it will not fit correctly.

How do I ensure the correct orientation during installation?

The lintel is designed with a distinct inner and outer profile. Ensure the side with the plaster key faces inward towards the room.

Troubleshooting

Lintel bowing or deflection after installation

Check that the load is evenly distributed and that the lintel was not overloaded beyond the design specification for its length.

Difficulty getting plaster to stay on the surface

Ensure the plaster key is clean and free of debris, and use an appropriate bonding agent if working in high-humidity conditions.

Surface rust appearing on the unit

Clean the area with a wire brush to remove oxidation and re-coat with a high-quality zinc-rich galvanized paint.

Pros and Cons

Pros

  • High structural integrity for heavy point loads
  • Enhanced corrosion resistance from galvanization
  • Easier installation due to lightweight design
  • Built-in plaster key simplifies interior finishing
  • Suitable for demanding structural applications like attic trusses

Cons

  • Requires precise cavity width matching
  • Large 3600mm length necessitates specific transportation and handling considerations
  • Not intended for non-load-bearing or non-cavity wall applications

Setup, Compatibility & Care

  1. Preparation: Ensure the masonry supporting the lintel is cured and level before placement.
  2. Bearing: Ensure at least 150mm of bearing on each end of the wall unless structural plans specify otherwise.
  3. Compatibility: Verify that your cavity width sits within the 150-165mm range. Using this with an incorrect cavity width may lead to stability issues.
  4. Handling: Although lightweight, the 3600mm length is cumbersome; use two or more people or mechanical lifting aids to prevent bending or injury during installation.
  5. Maintenance: Regularly inspect the exposed galvanized areas for any deep scratches that occurred during installation. If the steel base is exposed, apply a cold-galvanizing spray or zinc-rich paint to prevent localized corrosion.
