Birtley are the only lintel manufacturer to hot-dip galvanize after fabrication providing up to 50% more zinc protection than other approved coatings. Post-fabrication galvanizing leaves no surface with inferior paint protection.
Supergalv coating offers superior life expectancy.
Birtley's standard cavity lintels deliver up to 55% improvement on SAP default value in thermal bridging.
Lack of baseplate and factory fitted insulation reduces thermal bridging.
