Industrial Sliding / Folding Shutter Door Installs, UK
DP Doors & Shutters Folding Shutter Doors are hard to match for a strong, rubust door. The proportional movement of the door, controlled by a pantograph system, provides a design which is tough and yet smooth and easy to operate and which will tolerate the most extreme weather conditions.
The top hung, single or double units stack neatly to the side of the opening and occupy very little headroom. A floor channel is generally required but for certain applications a secondary top track can be fitted to prevent sway and allow an uninterrupted threshold.
As the doors can be arranged to fit around crane beams or railway catenary wires they are ideal for warehouses and locomotive or carriage sheds. Any number of fixed or floating door units can be combined to cover openings of virtually any width. Single or double units can be power operated and fitted with a wide range of control options.
See sheet FR5 for details of two and four hour fire rated Folding Shutter Doors.
Ribbed steel leaves, 230mm wide, with rolled edges hinge in patented pickets which are hung from a horizontal tubular track and guided in a channel set into the floor. Proportional movement is achieved by a series of bars in the form of a pantograph fitted to the inside faces of the pickets with pivoting and sliding connections. A fabricated leading edge strengthens the front of the door unit and carries pull handles, locking and the chain gripper for electrically operated doors.
All rolled components are supplied in galvanised steel. Other steel items are zinc plated except fabricated brackets which are primer painted.
