Structural reinforcements for lintels
Structural reinforcements for lintels – Lintels
The lintels are made of stainless steel and do not require any corrosion protection.
The standard line is designed to meet most load conditions found in residential and commercial buildings.
Special lintels can be manufactured to accommodate architectural features, heavy-duty applications, and wall constructions not covered by the standard range.
Nexus brick-clad lintels offer a quick and easy way to create deep soffits above window and door openings. They are ideal where speed is of the essence—the permanently bonded, off-site-applied brick slip cladding is manufactured from the same batch as the main masonry, ensuring a perfect match without compromising quality or appearance.

Cavity lintels for walls
These lintels are suitable for most residential and commercial developments and timber-framed structures. The perforations in the inner flange provide an integral plaster key.
SH lintels require a separate damp-proof course (DPC), while SU and SUX lintels act as an internal DPC, meaning that any water entering the cavity is automatically channeled down the lintel’s sloped face and drained externally.
When installing cavity wall lintels, the inner and outer sheets must be lifted together to avoid twisting the lintel; blocks must continue along the entire length of the inner flange. Masonry must have a maximum projection of 25 mm, and blocks must be laid as close as possible to the support. Point loads must be applied at least 150 mm above the lintel flanges.
Corrosion Resistance
All Cortartec lintels are manufactured from austenitic stainless steel and require no additional corrosion protection.
Thermal Performance
The thermal transfer, i.e., the “U-value,” of any wall construction depends on the thermal characteristics of the individual components being used. Cavity wall lintels are designed to allow the construction to continue up to the level of the window head.
Where required, cavity wall lintels are supplied insulated with CFC-free high-density polystyrene manufactured in accordance with BS 3837: Part 1: 2004 to be CFC-free with a zero ozone depletion potential.
CE Marking
Construction products falling within the scope of a harmonized European standard must now bear the CE marking under the Construction Products Regulation. For lintels, the harmonized standard is BS EN 845-2.
