Description The Birtley TF90 is a standard-duty steel lintel designed specifically for timber frame constructions with a cavity width of 90-105mm. The lintel provides structural support for external wall openings in timber-framed buildings and offers enhanced protection against corrosion through its post-fabrication hot-dip galvanizing process. Key Features: Application: Designed for timber frame constructions with a cavity size of 90-105mm. Pinch battens must be used for secure installation. Supergalv Coating: The lintel is hot-dip galvanized after fabrication, delivering up to 50% more zinc protection compared to other coatings. This extends the lintel's life expectancy significantly. Material: Made from Mild Steel S275JR to BS EN10025-2:2004, ensuring strength and compliance with industry standards. Fire Rating: Provides 60 minutes of fire resistance when finished with a two-coat plaster system. Post-Fabrication Galvanizing: Ensures all surfaces of the lintel receive equal protection with no inferior areas left untreated.
