Fire-Spec Lintels

Fire-Spec Lintels with enhanced fire resistance comply with BS8110-2 1985, Section 4 table 4.3 and as a result have a slightly less load bearing capacity when compared with the Hi-Spec Range.

Prestressed Lintels have a high span to depth ratio which results in lighter units and are marked at the ‘top’ to ensure correct orientation during installation.

Finish

An extruded concrete finish. For use normally in plastered situations. Not exposed situations.

Order/Specification Code

Prefix Hi-Spec reference with the word Fire (e.g. Fire S5)
