Part of the Birtley Group

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.

Birtley Galvanizing boasts one of the most impressive galvanizing plants in Europe. The plant achieves the finest quality hot-dip galvanized zinc protective coatings to BS EN ISO 1461. Using state-of-the-art technology the plant processes steel products using a computer controlled, automated handling system, enabling Birtley Galvanizing to provide full project solutions to many industries.
