How do you calculate a lintel?
- Measure the size of the structural opening i.e. the clear span between the masonry supports.
- Add 150mm minimum bearing to each end.

Similarly one may ask, how is lintel length calculated?
As standard our steel lintels increase in length by 150mm, the two values represent the length of the lintel that the values in that column relate to. If it is 600 | 1200 it means the load span details can be applied to any lintel between 600mm and 1200mm. Nominal height – The height of the lintel in mm.
Also, how much bearing should a lintel have? Steel Lintels should be installed with a minimum end bearing of 150mm, bedded on mortar and levelled along its length and across its width.
Just so, what size Catnic lintel do I need?
The length of lintel required is calculated by establishing the total width of the structural opening and adding 150mm (200mm for CXL lintels) end bearing allowance for each end. For example, an 1800mm structural opening will require a 2100mm lintel (2200mm for CXL).
How thick should a lintel be?
The steel for lintels, as a minimum, should comply with ASTM A 36. Steel angle lintels should be at least 1/4 in. (6 mm) thick with a horizontal leg of at least 3 1/2 in. (90 mm) for use with nominal 4 in.
