Superior industrial folding shutter doors are designed for heavy duty applications with large opening spans.
The shutters are made from 305mm wide x 1.2 or 1.5mm thick galvanised steel leaves which are formed to provide a continuously interlocking, weathertight installation completed by securely capped galvanised steel hinge strips.
A high security leading edge, fabricated from steel plate and channels into a rigid box section, is fitted with handles on both sides.
The gate frame is made from 25mm hot rolled channel pickets, interconnected by 30x10mm solid steel lattice bars for extra strength.
The doors are top hung from free running ball bearing pulleys that are connected to the pickets with zinc-plated bottom guide pieces which fit into a hot rolled steel bottom channel.
The top track incorporates two round-edge runner rails that ensure smooth running of the pulleys. The motor gearbox, tensioner and adjustable limits are surface mounted to allow easy access and the drive chain is completely enclosed to provide direct in-line transmission.
Superior industrial folding shutter doors are operated as standard by a 400 volt three-phase geared brake motor controlled by a constant pressure push button starter adjacent to the opening.
