Roll Up Shutter Repair

Keeping a Shutter Working

A roll up shutter is a curtain of interlocking slats that coils around a barrel above the opening, running in a guide each side, with a spring assembly inside the barrel taking the weight.

Everything wears, and on a commercial door it wears fast.

What Fails, and What It Costs

Damaged slats. Almost always the lower ones, and almost always a vehicle or a forklift. If the slat profile is still made, damaged slats can be replaced individually. That is a morning rather than a week, and a fraction of a recurtain. Profile availability is the deciding factor, so we identify it first.

Guides. Bent, packed with grit, or pulling away from the fixing. A curtain fighting its guide is the most common cause of an operator tripping out, and it wears the slat edges every cycle.

Bottom bar. Takes the impacts and holds the locks. Straightened where possible, replaced where the section is crushed.

Springs in the barrel. These carry the curtain weight. As they tire the operator does more, draws more current, and eventually trips. On a busy door this is a scheduled replacement item.

Bearings at the barrel ends. Squeal when dry, seize when ignored, and a seized bearing puts the whole load through the operator.

Why the Operator Is Usually Innocent

A striking share of commercial call outs are booked as operator faults and turn out to be mechanical.

An operator that trips its overload is doing its job: something downstream is taking more force than it should. A binding guide, a tired spring set, a curtain out of square. Replace the operator and the new one will trip too, once it has worn itself out doing the work.

So we check the mechanics first, every time.

Coastal and Industrial Together

Long Beach units get the worst of both. Salt air corrodes springs, bearings and fixings, and industrial dust packs the guides and grinds the slat edges.

The practical consequence is that guides need clearing and lubricating more often here than a manufacturer schedule suggests, and spring life comes in shorter than the rating.

Emergencies

If a shutter is stuck open the premises are insecure. Tell us that when you call. If a permanent repair needs a part we cannot get before morning, we can usually secure the opening so the unit is not left open overnight.
