Technical Specification

Heavy-duty door ideal for goods lifts,  the Ram-Fold Lift Shutter Door is designed to maximise the opening width, running smoothly along discreet top and bottom tracks with the shutter folding neatly to one side.   Rolled from a single sheet of steel, the one-piece picket ensures the lattice and leaf have an even operation within the door whilst retaining strength. The door consists of 152mm (6”) galvanised plain sections, hinged vertically by a continuous hinged strip.

Top track
The top track supports the weight of the door and is made from heavy gauge cold rolled
steel strip in a galvanised finish.

Pickets are made from galvanised rolled steel strip and form the main framework for the
door. The top of each picket is supported from the top track with a hardened steel grease
sealed multi ball roller. The bottom of each picket runs within the bottom track and gives
the door it’s strength.

6” leaves made from plain cold rolled galvanised steel strip.

Hinge strip
The hinge strip is capped cold rolled galvanised steel channel, which allows the leaves to
hinge vertically and move with the picket section when the door is operated.

The lattice is a unique shape for extra strength and is formed from heavy gauge cold
rolled galvanised steel strip. The lattice is bolted onto the pickets and controls the lateral
movement of the door, it also prevents the door from flattening out due to wind pressure.

Bottom track
The standard bottom track, which is set in the floor, is manufactured from heavy gauge
cold rolled steel strip and runs the full length of the door.

Leading edge
The leading edge is for accommodating hasp and staples, locks, handles etc and stiffens
up the front of each door.

Soffits and guide
Steel strip is folded using a press brake to the required size and shape and is fixed to the
door to give maximum security
