The History of Strongdor

Start of Strongdor - first building


Strongdor first started out in a small village in Bretherton. Our first container delivery of new doors in more than 25 variations arrived, starting the journey of becoming the company you see today. With the first year being a success, we installed a new paint line with an overhead tracking system to keep up with the high demand.


To increase capacity and efficiency Strongdor moves to a bigger and better manufacturing facility in Halton, Lancashire.

Strongdor once again outgrows the Halton unit and upscales to a factory based in Carnforth, enabling us to grow the Strongdor team for both office and factory staff. Double paint booths were also installed here to increase capacity and reduce lead times, meaning we could offer the best lead time in the industry.


A new ERP system was launched with a door configurator, enabling faster quote turnaround for our clients and increased hardware options from stock.



With staff numbers now over 50, Strongdor invests in a press brake and punch press machine shop facilities to manufacture doorframes in-house, significantly reducing lead times for customers.


Strongdor takes acoustic rated doors and security to the next level bringing new developments to market including Atakdor, the only door capable of resisting sustained attacks from a petrol Stihl® saw. Continuing to keep innovation at the front of everything we do to ensure our customers receive the products for their projects.



The expansion continues with Strongdor relocating operations by taking on another purpose built 42,000 square ft manufacturing facility in Morecambe, Lancashire. Featuring a high tech automation line including a Salvagnini and laser to offer enhanced accuracy, quality and service.


Marks Strongdor’s 12th Year Anniversary, the team continues to grow with over 80 staff and an expanded dedicated R&D Department. Despite the huge growth, Strongdor still continues to offer fast quotes, impeccable customer service and industry beating lead times.

Innovation Centre


As a company committed to delivering high quality steel doors tailored to the dynamic demands of the industry, we consistently strive for innovation and advancement in our product range. A significant stride in our endeavour unfolded in 2023 with the launch of the new Strongdor Innovation Centre, situated at our Carnforth, Lancashire headquarters.


As the team continues to expand, surpassing 100 members, the head office team outgrow their current space in Carnforth and make the move to a new office in Morecambe.
