Birtley Supergalv Lintels:

- The only range of steel lintels, fully hot-dip galvanized AFTER manufacture
- Best corrosion protection on the market
- Manufactured to BS845-2:2003
- Extensive range to suit every requirement
- No exposed edges or welds

All Supergalv steel lintels are protected by hot-dip galvanizing the complete lintel after fabrication. This process out performs all other protection systems by:

- Fully protecting every surface, cut edge and weld with a metallurgically bonded zinc coating, where other systems actually remove zinc during fabrication and do not provide full protection to all surfaces
- Creating a build-up of zinc coating at the most vulnerable points (edges etc.) which are more susceptible to damage on site and are the least protected in other systems
- Depositing a minimum zinc coating thickness of 65um in a metallurgical bond over the base steel
- Optional 'Ultragalv 2000' (U2k) corrosion protection system. This achieves a coating thickness of 150um by shotblasting the steel prior to galvanizing. This is up to 7 times more Zinc corrosion protection than other lintels, and the life of a Zinc coating is directly proportional to its thickness
