ATT Fabrications are suppliers of Bi-Folding Doors, Garden Rooms, Glass Roof Lanterns, uPVC, Aluminium and Composite Doors. We have been trading as a large, high volume fabricator supplying from our factory in County Durham in the North East of England for many years now, supplying the large DIY chains, trade and direct to the public. Over the years we have traded online via several websites, but as our business has grown, a decision was made to amalgamate our websites into one.
