The 2400mm Keystone SK-90 functions as a standard duty cavity wall lintel, offering structural support above wide window and door openings. This steel lintel is designed for external walls, fitting a cavity width between 90-105mm. It is built to support a 102mm outer leaf alongside a 100mm inner blockwork leaf, acting as a reliable load-bearing solution in conventional masonry builds.
During installation, blockwork should be built tight against the inner face of the lintel. A continuous mortar bed must be placed on the blockwork before positioning any floor units, which ensures the structural load is distributed evenly. Propping the lintel is recommended during the build to aid construction speed while the surrounding mortar sets. You can explore additional load-bearing options in our Steel Lintels category for a comprehensive project solution.
Formed from galvanised steel, the SK-90 lintel satisfies the thermal performance standards detailed by UK Building Regulations. This 2400mm version carries a safe working load, Total UDL 3:1, of 23kN and weighs approximately 21.5kg. Measuring 148mm in height with a 2mm material thickness, these technical parameters offer an exact balance of heavy load capacity and practical manual handling on site.
- Formed from galvanised steel to provide corrosion resistance in cavity walls.
- Accommodates a 90-105mm cavity width for standard masonry applications.
- Carries a 23kN safe working load at a 3:1 ratio for structural stability.
- Weighs 21.5kg to permit practical manual handling during installation.
- Complies with UK Building Regulations to ensure thermal performance.
