The HDBOX/K-150 solid wall heavy duty load bearing box lintel has been designed for use with either internal or external openings for heavy duty loading conditions to support concrete floors and point loads. These lintels are suitable for use with walls that are 150mm wide. The lintel has multiple small holes along its length which act as a plaster key.
This range of solid wall box lintels has been made from high quality pre-galvanised 2.5mm thick mild steel. These have been designed to carry the full load of wet masonry as soon as it has been installed.
These solid wall lintels are available in 150mm increments starting at 1950mm up to 2700mm, which allows for load bearing over a range of gap sizes for applications such as doors or windows.
Please note: These lintels require an additional 150mm end bearing at each end. For example: if the gap that needs to be bridged is 1950mm long, then an additional 300mm will need to be added to the total length.
In order for this lintel to support the specified loads below, the lintel will need to be installed correctly. Care should also be taken to avoid shock loading on box lintels when used with concrete floors or any other heavy units.
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
