Sliding Folding Steel Shutter (Concertna)

A strong and robust steel shutter 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.

Features and benefits:

• The doors can be arranged to fit around crane beams or railway catenary wires.
• Single or double units can be power operated and fitted with a wide range of control options.
• Leading edge, outer hinge strips, covers and the outside face of the leaves only, are colour finished. Internal door items, pickets and lattice bars are supplied in galvanized finish.
