It’s a question we get asked a lot, why do we galvanize our lintels after fabrication? Well, there’s a simple answer.
We do it because we want to know that each and every one of our lintels leaves our factory ready to stand the test of time, in even the most corrosive of environments.
We manufacture all of our lintels by cutting and bending steel, but unlike others, we then use our in-house galvanizing facility to seal and protect the underlying steel from the elements.
Without this additional layer of zinc protection, any cuts or welds would be exposed to the elements and corrosion.
Our unique manufacturing process allows us to offer a quality controlled product that will last the lifetime of the building.
Birtley began life as Birtley Building Products in 1965, based at the current site in County Durham. Originally a steel fabricator for the area’s mining and power generation industries, the company made its first steel lintels in 1967. Since then, Birtley has grown from reliable local supplier to a UK-wide force in construction design technology and product development.
In 1889, the British Metal Expansion Company was established in Hartlepool. It had sole European rights for the manufacture of expanded metal mesh, mainly for use as reinforcement and lath in the rapidly expanding sector of concrete construction. The business that grew from these early days later changed its name to Expamet.
Acquired by Birtley Group in 2015, Bowater Doors is a nationally-known name synonymous with top quality and imaginative composite residential door design and manufacture.
The product portfolio offers exclusive ranges for trade installers and a retail range providing doors direct to consumer and social housing organisations.
