The 2700mm Keystone SK-90 functions as a standard duty cavity wall lintel, providing necessary structural support over extensive window and door openings. Specified for external walls, this steel lintel is engineered for a cavity width between 90-105mm. It is designed to accommodate a 102mm outer leaf alongside a 100mm inner blockwork leaf, acting as an integral load-bearing solution in conventional masonry construction.
During the installation process, blockwork must be built flush against the vertical inner face of the steel lintel. A continuous mortar bed should be applied 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 browse further load-bearing options within our Steel Lintels category to meet the complete demands of your project.
Formed from galvanised steel, the SK-90 lintel satisfies the thermal performance criteria required by UK Building Regulations. This 2700mm structural component features a high safe working load, Total UDL 3:1, of 27kN and weighs 31.09kg. Measuring 161mm in height with a 2.5mm material thickness, these technical attributes present a highly reliable 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 27kN safe working load at a 3:1 ratio for structural stability.
- Weighs 31.09kg with a 161mm height to provide reliable load-bearing support.
- Complies with UK Building Regulations regarding thermal performance standards.
