Birtley Remains Open For Business

Birtley Remains Open For Business

In these difficult times, Birtley Group is still manufacturing and supplying products to exceed the current demand. The safety of our employees is paramount. We have made amendments to shift patterns and the office environment to ensure all of our employees are able to follow the social distancing advice to flatten the curve and protect those who are at risk.

As a group, we are in a great position to ensure continuity of supply. In 2019, we invested over £2million in our manufacturing facilities, including a new state of the art lintel production line to strengthen our position in the UK construction supply chain.

As a result, we have stock on hand to ensure our customers have access to the products and services they need to satisfy their customers. We would like to thank you for your continued support, we are all operating in unchartered waters but we will remain open and fully operational as long as it is safe to do so.

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.
