Welcome to the home of Birtley Supergalv Lintels
Birtley is the only lintel manufacturer to hot-dip galvanize after fabrication providing up to 50% more zinc protection than other approved coatings. Hot Dip Galvanizing to EN1461 offers superior corrosion protection and lifespan compared with pre-galvanized steel.
We offer a 65-150µm zinc coating thickness to suit life expectancy and exposure class. Our lintels are the only lintels to deliver consistent protection to all parts including welds and cuts, which are otherwise only protected by paint on pre-galvanized alternatives.
