Hi-Spec Lintels range:

This range of lintels is designed for use in plastered and rendered situations, delivering high performance while remaining cost-effective.

Hi-Spec Lintels are prestressed to ensure optimum performance, and all section sizes and lengths in this range come with a 30-minute fire rating as standard. Plus, due to the use of additives and resulting concrete strength, these units are also suitable for use below-ground.

Hi-Spec concrete lintels can be fixed into on-site, provided the prestressing tendons contained within the units remain undamaged. They can also be cut to length without adversely affecting product performance. For specific requirements or queries on this, contact Naylor Concrete's Technical team for guidance.

Pre-stressed concrete lintels ensure optimum performance and have a high span-to-depth ratio, which results in lighter units. Each Hi-Spec lintel is marked at the 'top' to ensure correct orientation during installation.

The Hi-Spec range is available in 14 different section sizes, in widths of 100 mm, 140 mm, 190 mm, and 215 mm, with lengths ranging from 900 mm to 3600 mm as standard, plus longer lengths of up to 4800 mm available on request for specific section sizes.
