Information
GDS roller shutter doors are designed for a wide range of applications which include factories, warehouses, industrial buildings, large commercial openings etc. A GDS roller shutter door can be used in practically any situation.
Some of the features that make our doors one of the best in New Zealand include:
- Interlocking galvanised steel slats
- Nylon end clips
- A range of operating options
Our doors are used primarily in industrial and commercial buildings. GDS Roller Shutters are custom built for each individual door opening. Shutters consist of a drum assembly mounted on a steel wall bracket. Curtains are made up from roll-formed individual interlocking steel slats which slide vertically within steel side guides. Operation is by hand, chain or electric motor.
Curtains
Curtains are constructed from roll-formed galvanised steel interlocking slats with an effective width of 100mm. Material thickness is normally .95 with .75 used on smaller shutters. Nylon end clips are fitted to alternate slats to prevent lateral movement and provide smooth, quiet operation. This means that greasing of guides (excluding windlock guides) is not necessary.
A bottom rail of 40mm x 40mm MS duragalv is angle bolted to the bottom slat on the curtain. On wider doors 2 angles are welded back to back to provide extra strength. Neoprene weather seals are fitted where required.
We are also able to provide:
- Bird proofing
- Perforated slats. The advantages in these are they offer security, visibility, ventilation and strength
- Aluminium interlocking slats
- Wicket gates
- Central sliding mullians for multiple door openings
Drums
The core of all our GDS Roller Doors is our custom fabricated mild steel tube drums with a minimum diameter of 150mm and a wall thickness sufficient to minimise deflection. Helically wound counter balance springs are contained within the drum.
The very top slat is then secured to the drum with high tensile bolts and wound on a special rig to guarantee a tight coil of slats on the drum.
Fitting
Guides are made of galvanised roll-formed steel channels with a minimum depth of 50mm and fitted with formed top entry bell mouths. There are also options available for the depth of the tracks, these being 75mm to 100mm.
Windlock guides are used on wider openings to help prevent extra movement in the door. All of our doors come with brackets that are fabricated out of 10mm thick mild steel plate and angle. Plates are slotted to allow for shaft and chain/motor mounting.
All components are either made from galvanised steel or are coated in a metal primed coating to protect them from deterioration.
Operation
Doors can either have a manual geared chain hoist or have electric operation. Motorized doors are supplied with the Grifco® Maestro range of industrial door operators with the latest electronics that improve installations and operation methods. Operators are either 3 phase or single phase electric motors. All motors have an automated emergency chain mechanism and a fully enclosed gearbox with an inbuilt limit control system.
Motor size is supplied to match door size:
- Motor .37kw suits up to about 28sqm
- Motor .75kw suits 32sqm-36sqm
- Motor 1.1kw suits 50sqm
Optional accessories include:
- Immediate upgrade to remote control. Operator remotes and reciever card
- Photo electric safety beams
- Ground loops for automatic opening
- Logic controls
- Radar activation
- Swipe card activation
Manually operated doors are easily able to be convereted to a motorised option at a later date if required.
Finish
The standard finish for all of our roller shutter doors is galvanised steel curtain and guides. All other components are metal primed.
Powdercoating of curtain prior to assembly is an option and there are over 70 different colours to choose from. To view a list of available powdercoat colours please view the colour chart.
