Multifold Gates

Metal multi-fold gates with a leaf design, available in a standard format or purpose-made to suit individual project requirements, to interface with and complement external building cladding features.

The gates offer practicality when designers are faced with limited side, head or back room which rules out rolling, overhead, hinged or sliding gates. The fact that the gates are sideways-opening means that the leading edges are in constant view, and therefore less prone to damage from vehicles passing through the opening.

The operation is straightforward and avoids the need for cables, springs, etc., thus avoiding high maintenance after installation.

Features and benefits:

• Gate leaves: the gate leaves are available in various designs, but typically comprise a 60 x 40 mm rectangular hollow section (RHS) perimeter frame with 25 mm diameter tubes, or 25 mm square hollow section (SHS) uprights at 125 mm centres. Higher gates have a mid-rail for strengthening purposes.

• Tracks: the gate leaves are hung on four-wheel, trolley-bearing hangers which incorporate the panel hinges, and run on a galvanized top track. An auxiliary top track is attached to allow the leaves 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 75 mm chase before finally being grouted into position.

• Gate arrangements: the gates 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 (bunching to one side) or bi-parting gate.

• Operation: the gates are electrically operated as standard, using a totally enclosed three-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.

Applications:

Suitable for securing larger car park entrances, whilst allowing the maximum ventilation necessary to allow exhaust fumes to escape.
