Door Dimensions
Maximum Height: 10000mm
Maximum Width: 20000mm
NOTE: Maximum dimensions are a guide only and may differ due to wind loading and cladding design, consult manufacturer for details.

Fold-Up Doors fit within the opening therefore it is highly recommended that all sides are plumb and true. IMPORTANT: Sufficient additional opening height, equivalent to the door thickness in the open position, must be taken into account when designing the opening. Refer to clearance detail data sheet and technical drawing.

Door Construction
The door is made up of a twin leaf door frame (hinged horizontally) and cladding. NOTE: It is the responsibility of the builder/designer to provide adequate structural columns/walls to carry all weight loads.

Door Frame
The door frame shall be constructed using rolled hollow section steel tube members, braced and trussed as required and designed in accordance with the Australian Standards to withstand wind loading in the closed position and provide minimum deflection in the open position. Frame, guides and fittings shall be prime coated with zinc rich chromate as standard and can be powdercoated or spray painted as specified.

Various types of cladding options are available such as steel, glass, aluminium, bar grille, mesh, plywood, woven wire, perforated sheet metal, insulation panels etc. See Cladding Options.

Personal Entry and Exit Doors (Optional)
Personal entry and exit doors may be incorporated in full or selected heights of the bottom leaf only. The door may be opened inwards as standard or outwards where specified. Personal entry and exit doors are fitted with a standard lock using Lockwood 201 night latch. Other locks may be available where specified.

Counterweight Covers

The counterweight shall be enclosed and protected using a heavy gauge steel cover to suit dimensions and shall be at a height of approximately three quarters of the door height as standard and fixed to the guide channel and wall.

Fold-Up Doors shall be fitted with padbolts (as standard) or patio bolts (when specified) internally and fitted to either side unless otherwise specified. Padlocks to secure the padbolts are to be supplied by others. If motorisation is required, the use of padbolts or patio bolts is not recommended due to self locking by the motor. Manually operated doors can be fitted with an automatic hold open locking device for when the door is in the fully open folded position.

Operating by means of counterweight balance the door lifts and folds into a horizontal position. under the lintel. The door travel is controlled by guide rollers operating in vertical guide channels thus allowing the hinges to pivot and the door to fold. In the open position the door projects internally and externally of the lintel. See Method of Operation.

Motorisation is highly recommended for large or heavy doors. See Industrial Operators.
