100mm
Are concrete lintels stronger than steel?
Strength. It is not a myth that steel lintels are stronger than concrete; this is generally the case, but it is a little more complicated. A high strength prestressed concrete lintel can often offer better supporting properties than a similar steel version at certain lengths and can be considerably cheaper.
What should a lintel sit on?
The lintel should be bedded on mortar and levelled both along the lintel and across its width. Full bricks, blocks or padstones should be used as bearing areas. DO NOT bear lintels onto cut blocks.
What is the maximum span for a concrete lintel?

Can you fix into a concrete lintel?

How much support does a concrete lintel need?
The standard bearing length for each end of a lintel is 6 inches or 150mm but on all occasions this must be checked with the building inspector. Once this bearing is established the lintel can be built in with bricks or blocks, paying normal regard to the procedure for laying them.
How thick should a lintel be?
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. (100 mm) thick brick, and 3 in.
