Steel lintel: need mortar bedding?
 

If I'm fitting a Catnic steel lintel into a new opening formed in a
brick wall (over a new window), should the ends rest directly on the 6"
of (flat) brick at either end, or on a bed of (stiff?) mortar placed on
the brick first? Building Control will be inspecting so whatever else,
it has to keep them happy!

(I'm thinking now that I do need the mortar; just that I've already
bought a made-to-measure window to fit a gap which I measured assuming
no mortar bed... not a massive problem to resolve but if I don't need
the mortar, no point in making extra work.)

If you dont use a mortar bed, the whole weight rests on one or 2
points, and brick failure is invited.
