Extended Product Information

FAQs

Can this lintel be used for external walls?

No, this is specifically designed as an internal box lintel.

What is the minimum bearing length required?

The manufacturer recommends a minimum of 150mm bearing on each end of the lintel.

Does the lintel require painting?

The galvanised finish is sufficient for internal conditions, but it can be painted if desired for aesthetic reasons.

Is this suitable for load-bearing walls?

Yes, it is designed for both load-bearing and non-load-bearing applications in 100mm walls.

How do I ensure a level installation?

Use a spirit level on the masonry bed before setting the lintel, and re-check once placed to ensure it sits perfectly horizontal.

Troubleshooting

Lintel is slightly short for the span

Ensure you have accounted for a minimum of 150mm bearing at each end; if the opening width is too wide for 1050mm, a longer lintel must be sourced.

Plaster failing to bond

Ensure the plaster key perforations are not blocked by mortar or dust and use a bonding agent if applying over particularly dense areas.

Pros and Cons

Pros

  • Lightweight construction reduces installation fatigue
  • Excellent rust resistance due to galvanised finish
  • Provides a secure, ready-to-plaster surface
  • High versatility for masonry or timber support

Cons

  • Specific to 100mm wall thickness
  • Requires professional installation knowledge
  • Limited to internal use applications

Setup, Compatibility & Care

To install, ensure the masonry below the lintel seat is level and clean. The lintel must have a minimum end bearing of 150mm on each side. When placing the lintel, ensure the perforated plaster key side is facing downward to receive the plaster finish. Avoid cutting the lintel with heat-generating tools as this can damage the galvanised coating; if cutting is required, use cold-cutting methods and apply a zinc-rich primer to any exposed metal edges. For maintenance, simply ensure that no moisture is trapped against the steel and keep the plaster key clear of excessive debris before application.
