Naylor S4 Hi Spec 100 x 100mm Concrete Lintel

The Naylor S4 Hi-Spec 100 x 100mm Concrete Lintel is a precast concrete lintel designed for plastered or rendered walls, delivering reliable load capacity and straightforward installation.

Manufactured in an ex-steel mould from Wet Cast Concrete, it achieves a concrete strength of 50 N/mm2 and complies with BS EN BS8110-2 S4 lintel requirements. The S4 is finished with an extruded concrete surface and marked with TOP for easier on-site orientation.

Hi-Spec lintels are pre-stressed, enhancing strength and enabling heavier loads and longer spans than non-prestressed designs. This approach supports lighter units for easier handling and installation on site, while maintaining robustness and reliability in construction sequences.

Ideal for tradespeople working on plastered or rendered walls, with suitability for below-ground applications where required. The 30-minute fire rating adds a practical safety margin in line with typical internal partition and load-bearing scenarios. CE marking is available on request, and our Technical Team can advise on sizing, installation and compatibility with your project.
