Rolling Shutter Doors
Our Industrial Rolling Shutter Doors have been specifically developed for a
wide range of applications including Factories, Warehouses, Workshops and Farm
Buildings. These doors are available in a choice of finishes including
Galvanised, HP200 Colorcoat Plastisol and Polyester Powder Coat finish. The
doors can be operated manually either push up/pull down or via endless hand
chain through a reduction gear set with the assistance of counter-balance
springs. They can also be operated electrically via a 240 volt single phase or
415 volt three phase motor units through various types of controllers.
Insulated Sectional Overhead Doors
Our Insulated Sectional Overhead Doors are an effective barrier for both
security and thermal insulation purposes. Suitable for a wide range of
industrial applications, the construction of the door results in an overall 'U'
value of 0.6 W/m A variety of track arrangements is available to suit standard,
low and high headroom applications. The doors are finished as standard in HP200
Colorcoat Plastisol to the external face. The doors can be operated manually
either push up/pull down or via endless hand chain through a reduction gear set
with the assistance of counter-balance springs.
High Speed Doors
These doors are very well suited to entrances subject to heavy and continuous
traffic and intensive use. The construction of our High Speed Doors along with
the operating speed can reduce the level of energy loss dramatically. Available
in both horizontally Rolling and Folding options, they are structurally highly
flexible with transparent or coloured (or a combination of both)
interchangeable panels, therefore in the case of accidental impact, the damaged
panel can be replaced easily and quickly, thus keeping repair costs minimal.
Operation is via a 415 volt twin-speed three phase motor unit through various
types of controllers including push button stations, remote control and floor
inserted induction loops.
