Industrial roller shutter doors are the core of what we manufacture. They span the wide openings on loading bays, warehouses and factory elevations, take daily punishment from forklift traffic and weather, and are expected to open first thing every morning for a decade or more.
Built to the opening, not to a catalogue
Every industrial door we make is manufactured to the measured structural opening at our Sandton works. On wide spans this matters: a curtain that is even slightly out of square binds in the guides, and binding is what kills motors and springs early.
Specification
- 0.8mm to 1.2mm galvanised steel slat, gauge selected for the span
- Openings up to 8 000mm wide
- Manual chain hoist, or single and three-phase motors with manual override
- Wind-locked curtain options for exposed elevations
- Safety edge, photocells and audible warning where the duty requires it
- Powder-coated over galvanising for colour matching
Getting the duty right
The most expensive mistake on an industrial door is under-specifying the drive. A bay that cycles forty times a day needs a different motor and spring assembly to one that opens twice. Tell us the traffic and we will size it properly — it costs a little more upfront and considerably less over five years.
Wind and exposure
Wide doors on exposed elevations need wind locks that hold the curtain in the guides under pressure. Coastal and highveld sites in particular should not be quoted without this being considered. We check it on the site survey.
Getting a price
Send us the opening width and height and a photo of the elevation. That is usually enough for a budget figure, and we will follow up with a free site survey and a costed quote within one working day of measuring.
Built for the way industrial doors actually get used
An industrial shutter on a working site is not a security product that occasionally moves — it is machinery that runs all day. Loading bays, dispatch doors and workshop fronts take forklift traffic, weather and constant cycling, and the failures that follow are entirely predictable: fatigued springs, drifting limits, guides packed with debris and bottom rails bent by a reversing vehicle.
We build against that. Heavier slat gauges where the span demands it, high-cycle spring assemblies rated to your measured usage, three-phase drives with manual chain override, and reinforced bottom rails on any opening where vehicles operate. Galvanised is our default because the zinc is bonded to the steel rather than sprayed over it.
How we build it
Every door is manufactured to your measured structural opening at our Sandton works in Tarlton, not cut down from a stock size. Slat is roll-formed on our own line, guides are cut and drilled to the opening height, and the springs are wound to balance the finished curtain weight. Powder coating is applied after fabrication so the colour holds across the whole assembly rather than just the visible slat.
What decides the specification
Two things: the width of the opening and how often the door moves. Spring life is measured in cycles rather than years, so a door opening forty times a day needs a different spring and drive to one opening twice, even at identical dimensions. After that it is environment — salt air, washdown, dust or forklift traffic each change the material and the hardware. That is why we survey before quoting.
Installation and handover
Fitted by our own teams, never subcontracted. Guides are set plumb and square, the curtain is hung and balanced, limits are set, and every safety device is tested and adjusted within safe closing force before we leave. You get a demonstration of normal operation and of the manual override, because the first time you need that override should not be during an outage.
Warranty and aftercare
Workmanship is covered for twelve months and motors carry their manufacturer warranty, which we register for you. Because we manufactured your door, we can tell you its exact specification years later and we hold the wear parts for it rather than ordering them in — which is the practical difference between a repair that happens this week and one that waits on a supplier.
