The Birtley CB50 is a standard-duty steel lintel designed for cavity walls with a cavity size of 50-65mm and an inner and outer leaf thickness of 100mm. This lintel is ideal for general masonry support but is not suitable for point loads or concrete floors . It is optimized for long-lasting performance with a post-fabrication hot-dip galvanizing process, providing enhanced protection against corrosion. Key Features: Application: Suitable for cavity walls with a cavity size of 50-65mm and a 100mm inner and outer leaf. Not intended for use in applications with point loads or concrete floors. Supergalv Coating: Post-fabrication hot-dip galvanizing provides up to 50% more zinc protection, ensuring longer life expectancy. No surface is left with inferior paint protection. Material: Made from Mild Steel S275JR to BS EN10025-2:2004, ensuring high structural performance. Thermal Bridging: The lintel's design lacks a baseplate and factory-fitted insulation, reducing thermal bridging.
