Extended Product Information

FAQs

Can I use this for a conservatory roof support?

No, this lintel is intended for standard masonry and timber floor loads and is not rated for concentrated point loads like those from conservatory roofs.

Is this lintel suitable for attic trusses?

No, this product is not designed to support attic trusses or precast concrete floor systems.

What is the required end bearing for this lintel?

The manufacturer recommends a minimum end bearing of 150mm at each support point.

Does this lintel require painting or protective coating?

While it comes ready for standard use, ensure it is properly embedded in mortar to protect it from moisture. Avoid removing factory-applied coatings.

Can I use this for a 170mm cavity?

No, this lintel is specifically engineered for a 150-165mm cavity range. Using it outside of these dimensions may cause structural instability.

Troubleshooting

Lintel does not sit flush in the cavity

Verify that your inner and outer leaf measurements match the 100-115mm and 100mm requirements respectively.

Plaster finish is cracking or uneven

Ensure the built-in plaster key is free of excess debris and mortar, and check that the lintel was installed level.

Pros and Cons

Pros

  • Lightweight construction facilitates easier on-site handling
  • Integrated plaster key simplifies the finishing process
  • Perfectly sized for standard 150-165mm cavity wall specifications
  • Reliable support for domestic masonry and timber floors

Cons

  • Not suitable for heavy point loads
  • Cannot be used for attic trusses or precast concrete floors
  • Requires adherence to specific leaf thickness constraints

Setup, Compatibility & Care

For optimal performance, the lintel must be installed with a minimum end bearing of 150mm at each support point. It is strictly compatible with 100-115mm inner leaf and 100mm outer leaf wall construction. During installation, avoid modifying the lintel or drilling into the steel as this may compromise its load-bearing capacity. Keep the lintel free from mortar splatter on the plaster key area to ensure a smooth finish. Regularly inspect for signs of corrosion if exposed to coastal or aggressive environments, and store in a dry, covered area prior to installation to prevent pre-mature oxidation.
