The Naylor S4 Hi-Spec concrete lintel has a 100 × 100mm section and is designed for openings in 100mm-wide walls and partitions where a prestressed concrete lintel is suitable. Its textured, extruded finish is intended for plastered or rendered situations, and Naylor declares 30 minutes of fire resistance as standard. Choose a length to suit the clear span, required end bearings and design loads, using the manufacturer's current technical information.
