Naylor Lintels have a low water absorption and as a result of the quality-controlled hi-spec dense concrete mix used in their manufacture, they can be used underground providing that the ends of the units are encased in a minimum of 45mm of mortar to the ends of the reinforcing strands.

All Naylor Lintels are wet cast and have a concrete strength of 50 kN/mm2. They are suitable to accept fixings providing that the tendons contained inside the unit remain undamaged.

All fire rated lintels produced by Naylor Lintels comply with BS8110: table 4.3: section 2: 1985.

All L-Strip’s are manufactured from steel complying with BS EN10025 with a minimum yield stressed of 275 N/mm2. Zinc coating is galvanised to BS2929z2. Stainless Steel L-Strip’s are also produced conforming to grade 304:S15:BS1449: Part 2.

Implementation of the amendments to part E and L of the Building Regulations came into force in 2002. Amongst the new measures it is required that the thermal bridging and fabric insulation be improved (part L) and the resistance to sound reverberation, especially at low frequencies, (Part E) be increased.

Compliance with the new regulations can easily be achieved using our range of lintels.

Lintels can be manufactured to lengths up to 4800mm dependant upon the section size. Lintels can also be cast with inserts and channels. Please speak to our technical department for assistance.
