Birtley Heavy Duty Steel Cavity Wall Lintel 4200mm x 156mm - HD50/130

The HD50/130 lintel is designed for cavity wall constructions where the inner leaf is wider, making it ideal for walls with 125-140mm inner leaves and 100mm outer leaves . It provides heavy-duty structural support with superior corrosion resistance and thermal performance. This lintel must have a solid, fully jointed blockwork infill to the inner leaf. Key Features: Cavity Size: 50-65mm. Outer Leaf: 100mm. Inner Leaf: 125-140mm wide. Material: Structural grade steel (S275JR/S355JR to EN10025-2:2004). Supergalv Coating: Provides superior life expectancy through post-fabrication galvanization for enhanced corrosion resistance. Lack of Baseplate: Reduces thermal bridging and improves overall thermal performance.
