FAQs

What is the intended cavity range for this lintel?

Can this be used for residential projects?

Yes, it is designed for both residential and commercial construction applications.

What are the dimensions of the leaves?

Troubleshooting

Lintel does not sit level across the opening

Verify the supporting masonry is perfectly level and plumb before installation; adjust the mortar bed depth to compensate for minor irregularities.

Visible signs of surface corrosion

Clean the affected area and apply an appropriate anti-corrosive metal primer or paint to protect the steel surface.

Setup, Compatibility & Care

Proper installation begins with verifying the wall cavity width falls within the 150-165mm range. When installing, ensure the lintel has the required minimum end bearings—typically 150mm at each end unless specified otherwise by your structural engineer. Care should be taken to protect the steel finish during installation to prevent premature oxidation. For long-term care, verify that the cavity tray and weep holes are correctly positioned relative to the lintel to manage moisture accumulation effectively. When storing on-site, keep the steel units off the ground on timber sleepers and cover them to protect against excess moisture.
