Profile: Three Counties Steel Buildings Ltd. is a supplier of domestic, commercial and industrial steel buildings. We offer a full fitting out service. We offer roller door option, sectional overhead, sliding, concertina steel, rapid and strip curtain doors. Our light duty steel door is formed from a continuous single `skin' which flexes to allow the door to be rolled. Our steel sectional overhead door is constructed from horizontal panels (each panel typically in the region of 400 mm wide) which slide on a track up into the roof in a gentle arc. The steel door therefore is not rolled up, as a steel roller door does, but moves into the roof space above the door entrance. We also provide project management services.
