A prestressed lintel _can_ be composite or non-composite. Composite
lintels need the action of three courses of brickwork (or two of
blockwork). These are usually the 65mm deep ones. Non-composite
don't need the masonry above, and come in depths of 100mm or more.
Yours are, therefore, composite ones.

Nope - mine is the Naylor P100 which I believe are non-composite. However I
will check this with them tomorrow just to make sure.



I would run with the ****ing people off angle; you're doing a damn fine
job at it with me.
