Hart Door Systems, the first specialist door company in the UK to manufacture high-speed doors, has moved into a series of short films to high-light its successes.
The most recent is a profile of Hart’s work at Komatsu’s 200,000 sq m plant at Birtley, Co Durham, where Hart has installed over 60 doors across a range of door types including Speedor Cleanrooms, Speedor Storms and electric roller shutters.
