TOP TRACK
The top track supports the weight of the door and is formed from heavy gauge rolled steel strip. It is fixed to the lintel with fabricated mild steel brackets where required and is galvanised or painted depending on the door specification and size.
LEAVES
The leaves, which are 230mm (9”) wide, are formed from cold roller galvanised steel strip and are ribbed for aesthetic purposes and extra strength. The gauge varies to suit the size of the door.
HINGE STRIP
The hinge strip is a capped, cold rolled, galvanised steel outer channel that allows the leaves to hinge vertically and move with the picket section when the door is operated.
LATTICE
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 sideways movement of the door and prevents the door from flattening out in high winds.
BOTTOM TRACK
The standard bottom track, which is set into the floor, is manufactured from heavy gauge cold rolled steel strip and runs the full width of the door.
LEADING EDGE
The leading edge is for accommodating hasps and staples, handles etc. and stiffens up the closing edge of each door. It is formed into a deep channel from heavy gauge galvanised steel strip.
SOFFITS & SIDE CLOSURES
Heavy gauge galvanised steel strip is press braked to the required size and shape and fixed to the doors and door jambs to give maximum security.
HARDWARE
Each door has a bow handle inside and out and is fitted with a heavy duty hasp and staple to take the customer’s own padlock. Normally fitted on the inside unless otherwise specified.
ELECTRICAL OPERATION
Electrical operation can be provided by means of a 415v three phase geared electric motor with open/close/stop operation by means of a push button control panel. A manual disconnection device allows the door to be hand operated in case of power failure. Each motor unit is complete with torque limiter that stops the door at each end of its travel.
