Brickwork over openings
Where brickwork runs over openings for windows and external doors, lintels are required to support the brickwork. Lintels are made of hot dipped galvanised mild steel. They are usually in the form of angles, flats or T-sections.
Adequate support must be provided where the lintels land on the brickwork. The following table gives minimum end bearings.
| Span | Conventional sections | Proprietary lintels | Minimum end support (mm) |
|---|---|---|---|
| Up to 1 m | 75 x 10 flat bar | 85 flat | 90 |
| Over 1 m to 2.1 m | 100 x 100 x 8 angle | 100 x 100 angle | 100 |
| Over 2.1 m to 3.6 m | 150 x 100 x 8 angle | 150 x 100 angle | 150 |
