The CFS/K-90 extra heavy duty load bearing lintel has been designed to support heavy duty loads for cavity walls which have a width between 90mm and 105mm. This lintel has a 95mm wide outer leaf which is suitable for standard brickwork. The inner leaf is 100mm wide which is suitable for standard blockwork.
These heavy duty lintels are available in 150mm increments starting from 750mm up to 4800mm, which allows for load bearing over a range of opening sizes for various applications such as for windows or doors.
Please note: For correct installation, the lintel requires a 150mm end bearing at each end of the lintel. For example: if the opening is 1200mm then the lintel length will require an additional 300mm to accommodate for these end bearings.
This range of standard 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 lintels have been tested as a composite unit with surrounding masonry and have been built in accordance with BS EN 1996-2:2006. 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
