IG Extra Heavy Duty Steel Cavity Wall Lintel 4650mm x 234mm - L5/75

The L5/75 is an extra heavy-duty steel cavity wall lintel designed to support significant structural loads in cavity walls with cavity widths of 70-85mm. It is commonly used for large openings in load-bearing walls, such as those for doors and windows, where enhanced strength is required. Key Features: Extra Heavy-Duty Load Support: Suitable for structural applications with high load requirements. Cavity Width: Specifically designed for cavity widths between 70-85mm. Manufacturing Length: Available in lengths in 150mm increments to suit a range of structural openings. Blockwork Integration: The lintel must be built tightly with the blockwork for proper support. It's essential to ensure that all vertical and parallel joints are fully filled with mortar to maximize load-bearing capacity. Mortar Bed: A mortar bed should be placed on top of the blockwork before laying floor units, ensuring even distribution of load across the structure. Propping: Lintels may be propped during construction to speed up the build process while maintaining safety and structural integrity. This lintel is ideal for demanding applications where extra support is needed to maintain the stability and load distribution of large openings.
