The 1800mm Keystone SK-90 is a standard load cavity wall lintel designed to provide structural support over window and door openings. Specified for external walls, this steel component is suitable for cavity widths between 90-105mm. It is engineered to carry a 102mm outer leaf and a 100mm inner blockwork leaf, serving as an essential load-bearing element in traditional masonry construction.
During the build, blockwork must be laid flush against the inner face of the steel lintel. A continuous mortar bed is required on top of the blockwork before floor units are positioned, ensuring the structural load is distributed evenly. Propping the lintel is advised to aid construction speed while the surrounding mortar sets. You can explore further load-bearing components within our Steel Lintels category to complete your project requirements.
Formed from galvanised steel, the SK-90 satisfies the thermal performance standards outlined by UK Building Regulations. This 1800mm version carries a safe working load, Total UDL 3:1, of 19kN and weighs 14.02kg. With a height of 107mm and a 2mm material thickness, these specifications deliver a precise balance of heavy load capacity and manageable manual handling on the building site.
- Formed from galvanised steel to ensure corrosion resistance in cavity walls.
- Accommodates a 90-105mm cavity width for standard masonry applications.
- Carries a 19kN safe working load at a 3:1 ratio for structural stability.
- Weighs 14.02kg to permit practical manual handling during installation.
- Complies with UK Building Regulations to ensure thermal performance.
