Birtley Building Products Ltd is a wholly-owned subsidary of Hill & Smith Holdings PLC.

The company produces a wide range of supergalv lintels and balconies, offer galvanizing services and produce a wide range of doors.

Furthermore the company is demonstrably innovative in meeting the demands of the modern construction industry by developing new products and systems.

Typical of these is a brand new selection of 'Juliet' balconies and the company's latest introduction - 'Bay 6': a unique and revolutionary corner window support system.

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.

Corrosion Protection
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.
