Roller Shutter Doors Jacobs

KwaZulu-Natal

Suburbs we cover here: Jacobs, Mobeni, Clairwood, Prospecton

Jacobs, Mobeni, Clairwood and Prospecton form Durban South’s heavy industrial corridor — chemical plants, petroleum facilities, port logistics and automotive assembly adjacent to the Bayhead port precinct. This is one of the most demanding environments in the country for roller shutter door specification. Port-adjacent salt air, chemical aerosols from neighbouring facilities and constant moisture make this a place where the wrong specification does not just underperform — it fails fast and expensively.

What we do in Jacobs

We are manufacturers rather than resellers. Every door is cut, rolled and assembled at our own Sandton works in Tarlton and installed by our own teams, which is why we can still tell you the slat gauge, spring rating and drive specification of a door three years after we fitted it. In Jacobs that covers industrial roller shutters on warehouse and factory openings, security shutters on trade counters and street-facing units, insulated doors on domestic and estate garages, and the repair and servicing work that keeps all of them running.

Why specification matters more on the coast

Salt-laden air is the difference between a door that lasts fifteen years in Jacobs and one that is rusting at the cut edges inside three. Painted steel fails where the coating is thinnest — drilled holes, fixing points, the sheared edge of every slat — and once moisture is beneath the paint it travels sideways under it. Repainting hides that for a season and then it returns worse.

Our default here is galvanised slat, where the zinc is metallurgically bonded to the steel rather than sprayed over it, with marine-grade fixings, sealed bearings and guide rails detailed so wind-driven spray drains instead of collecting. On exposed openings we specify it as standard rather than as an upgrade line on the quote, because on the KwaZulu-Natal coast it is not optional.

How a job runs

You send us the approximate opening size, or a photograph if that is easier. We survey the structural opening, headroom, side room and power supply on site — free within our standard travel radius. You get an itemised quote covering the door, the drive, the installation and anything the opening needs before a door can go in, usually within one working day of the survey. We then manufacture to your measurements at the factory and our own team fits it, sets the limits, tests the safety devices and shows you the manual override before leaving.

Repairs and breakdowns in Jacobs

Most of our repair work is on doors somebody else installed, and we handle all common makes of roller shutter, sectional overhead and high-speed door. The failures are predictable: fatigued torsion springs, limit switches drifting out of adjustment, guide rails packed with debris, bottom rails bent by a reversing forklift, and motors that were carrying more weight than they were rated for. A door stuck open is a security problem and a door stuck shut is a trading problem, and both are attended as emergencies rather than booked in for next week.

After the installation

Workmanship is covered for twelve months, and motors and components carry their manufacturer warranty, which we register on your behalf. Beyond that we service what we sell. Most of the emergency callouts we attend anywhere were preventable: springs fatigue predictably, limit switches drift gradually and guide rails fill with debris slowly, all of it visible months before the door actually stops. A scheduled visit costs less than the callout it replaces on any door that works for a living.

Doors we fit most often in Jacobs

• Industrial roller shutters — galvanised slat, openings to roughly 8 000mm wide, chain hoist or three-phase motor
• Security shutters — solid, punched or grille curtains with anti-lift locking for shopfronts and trade counters
• Domestic roller doors — insulated aluminium, quiet operation, remote control and battery backup
• Motorisation of existing doors — remotes, keypads, loop detectors, safety edges and manual override
• Fire-rated shutters — rated assemblies integrated with the building fire panel

Getting to Jacobs

Jacobs is roughly — from our factory at Tarlton, Krugersdorp. Because it is a distance from the factory, we schedule the survey and the installation as a single trip rather than charging you for two, and we give you a realistic date rather than a comfortable one.

We cover Jacobs, Mobeni, Clairwood, Prospecton and the surrounding areas. If your street is not on that list, phone and ask — the boundary is about travel time, not a line on a map.
