The HD50 lintel is a heavy-duty cavity wall lintel designed for applications with 50-65mm cavities and 100mm outer and inner leafs . It is designed for robust structural performance and durability. The HD50 lintel must have solid, fully jointed blockwork infill to the inner leaf to ensure optimal support and stability. Key Features: Cavity Size: 50-65mm. Outer and Inner Leaf Width: 100mm. Material: Structural grade steel (S275JR to BS EN10025-2:2004). Supergalv Coating: Provides superior life expectancy with enhanced corrosion resistance through post-fabrication galvanization. No Baseplate: Lack of baseplate and factory-fitted insulation reduces thermal bridging, contributing to improved thermal performance.
