Sliding Folding Shutter Doors

When large entrances are in constant use, security can easily be compromised, but our Folding Shutter Doors solve this problem. Framed on twin channels with precision pulleys, these doors are quick to open even across large spans. Reliable, with low maintenance, their concertina constructions allows them to be pulled aside for maximum clearance

DESCRIPTION

These doors are designed for use within industrial premises to provide a maximum vertical opening for large vehicles, buses and aircraft whilst also providing a flexible horizontal opening that can be minimised to prevent heat escaping from the premises or cold air entering them.

SPECIFICATION

 

Top Track - The top track supports the weight of the door and is formed from heavy gauge cold 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.

 

Pickets - Pickets are formed from galvanised cold rolled steel strip and form the main framework for the door on the inside of the building. 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

its strength in high winds.

 

Leaves - The leaves, which are 300 mm (12”) wide as standard, are formed from cold rolled galvanised steel strip and are ribbed for aesthetic purpose and extra strength. The gauge varies to suit the size of the door. Smaller 150mm (6”) and 275mm (9”) leaves are also available to suit special applications.

 

Hinge Strip - The hinge strip is a capped cold rolled galvanised steel outer channel, which 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 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 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. It is formed into a deep channel from heavy gauge galvanised steel strip.

 

Soffits and Side Closures - Heavy gauge galvanised steel strip is press braked to the required size and shape and fixed to the doors and doorjambs to give maximum security.

 

Hardware - Each door has a bow handle inside and out, and is fitted with a heavy-duty hasp and staple, which is normally fixed inside unless otherwise specified. The hasp and staple is to take the customer’s own padlock.

 

Electric Operation (when quoted) - The operation is by 415v 3ph geared electric motor with a manual disconnection for hand use during emergencies. The starter contains OPEN, STOP and CLOSE buttons plus a safety thermal cut out switch. The drive to the shutter is provided by a continuous chain drive system running at top track level.

N.B. 3 phase isolator with neutral and earth to be sited by client 1 metre from opening.
