The 750mm Keystone SK-90 acts as a standard load cavity wall lintel, providing essential structural support above narrower window and door openings. Specified for external walls, this steel lintel is designed to suit a cavity width between 90-105mm. It easily supports a 102mm outer leaf alongside a 100mm inner blockwork leaf, establishing itself as a fundamental load-bearing component in traditional masonry builds.
During installation, blockwork must be built tightly against the inner face of the steel lintel. A continuous mortar bed should be applied directly to the blockwork prior to placing any floor units, ensuring the heavy structural weight is evenly dispersed. We recommend propping the lintel during the build to maintain construction speed while the surrounding mortar sets. You can explore further load-bearing options within our Steel Lintels category to meet the complete demands of your project.
Produced from galvanised steel, the SK-90 lintel satisfies the thermal performance criteria required by UK Building Regulations. This 750mm structural component features a safe working load, Total UDL 3:1, of 12kN and weighs 4.47kg. Measuring 88mm in height with a 1.6mm material thickness, these technical attributes present a highly reliable and manageable solution for load-bearing support on the building site.
- Formed from galvanised steel to ensure corrosion resistance in cavity walls.
- Accommodates a 90-105mm cavity width for typical masonry applications.
- Carries a 12kN safe working load at a 3:1 ratio for structural stability.
- Weighs 4.47kg to permit practical manual handling during installation.
- Complies with UK Building Regulations regarding thermal performance standards.
