HD/K-110 - Heavy Duty Load Bearing Cavity Wall Lintel

HD/K-110 - Heavy Duty Load Bearing Cavity Wall Lintel

The HD/K-110 heavy duty load bearing lintel has been designed to bear a heavier load than a standard cavity wall lintel. It is suitable for cavity walls with a cavity width of 110mm to 125mm. The lintel has an outer leaf with a width of 95mm, but is able to support bricks with a width up to 102mm (95mm leaf width + 7mm overhang). The inner leaf has a width of 100mm and is able to support blocks of the same width.

These heavy duty lintels are available in 150mm increments starting from 750mm up to 4050mm which allows for load support over a wide variety of gap sizes for a variety of uses such as for windows and doors.
Please note: The lintel will need an additional 150mm end bearing for each end of the lintel. For example: if the gap that needs to be bridged is 1800mm then an additional 300mm will need to be added to the total length of the lintel.

This range of heavy duty load bearing lintels has been made from high quality pre-galvanised mild steel and satisfy the thermal performance requirements of England and Wales’ part L of the building regulations, Northern Ireland’s part F and Scotland’s technical handbook, section 6.

In order for this lintel to support the specified loads below, the lintel will need to be installed correctly.

The figures also take into account the different loading types which are common in traditional cavity wall construction. These figures have been acquired through testing in accordance with the requirements of standards BS 5977 Part 2: 1983 and BS EN 845-2:2003
Differential Total UDL kN 3:1 (up to 75% loading on the inner leaf)
Differential Total UDL kN 19:1 (up to 95% loading on the inner leaf)
