Facing Masonry Reinforced Concrete Beam Lintels to BS EN 845–2:2003.

Rectangular in cross-section and the top of the units are marked to assist with the correct on-site handling and insitu building-in.

The lintels require 215 mm long end bearings at both ends. Therefore to calculate the overall length of a lintel 430 mm (2 x 215 mm) should be added to the structural opening dimension.

Units are frost resistant when built in accordance with PD 6697 and have a coating reference C1 unless otherwise ordered.
