Standard specification

Panels

The door panels are constructed from internal steel sections with flat galvanised facing sheets on both sides. They are infilled with a high density insulation material and have an overall thickness of 63mm.

Tracks

The door panels are hung on four wheel trolley bearing hangers which incorporate the panel hinges and run in a galvanised top track. An auxiliary top track is attached to allow the panels to fold correctly. Brass rollers connected to the bottom hinges run in a steel channel bottom track which is set for alignment within a 200 x 75mm chase before final grouting into position.

Door arrangements

The doors are normally face fixed to the inside of the opening but can be arranged to mount directly between jambs. They can be supplied as a single door (bunching to one side) or bi-parting.

Operation

The doors are electrically operated as standard using a totally enclosed 3 phase motor gearbox mounted on the top track with open/close/stop push buttons adjacent to the opening at the slam side. Disconnection or emergency manual operation is provided at low level adjacent to the motor. Safety edges are fitted as standard to the leading edges.

Finish

The majority of parts are galvanised with other components prime painted.

Polyester powder coating to a range of standard colours is an optional extra.
