Fire-Rated Roller Shutter Doors in Cape Town

• Fail-safe gravity descent, no power needed
• Fire panel integration and drop testing

A fire-rated roller shutter door is a certified assembly, not simply a heavy door. It exists to hold a compartment line for a stated period, and it only does that if the curtain, the guides, the barrel, the fixings and the release mechanism are all part of the tested specification. Cape Town sites with rated openings need the certificate as much as the door.

Fire-rated roller shutter doors we supply in Cape Town

• Rated curtain assemblies supplied to their tested specification with documentation.
• Certified guides and fixings, because the rating covers the assembly rather than the curtain alone.
• Controlled descent so the door closes at a safe rate instead of dropping.
• Fusible link or detector release, interfaced to the fire panel where the design requires it.
• Insulated variants where the specification calls for integrity and insulation.

Where fire shutters are needed in Cape Town

Manufacturing, distribution and cold storage through Epping, Montague Gardens, Airport Industria and Paarden Eiland. Service corridors and back-of-house openings at the V and A Waterfront, Canal Walk, Cavendish and Tyger Valley. Plant, generator and switch rooms. Basement parking in the many apartment buildings through the City Bowl, Sea Point and Century City.

Corrosion and the release mechanism

This is the coastal problem with fire shutters, and it is a serious one. The release is a mechanical device that has to move once, after years of doing nothing, in an environment that seizes mechanisms. A fusible link fitting that has corroded, or a descent brake that has never been exercised, turns a certified door into a heavy door. We operate the release in full at every test and report a stiff one as a failure rather than an observation.

Ratings and what they mean

A rating is a period of integrity under test conditions, commonly sixty or one hundred and twenty minutes, and it is a property of the tested assembly. Fitting a rated curtain into non-rated guides, or anchoring it into an unsuitable substrate, voids the rating regardless of what the curtain is made of.

Retrofitting into older Cape Town buildings

A rated door has to be anchored into rated construction, and in the older City Bowl, Woodstock and Salt River stock the wall around an opening may not be what the drawing says. We check what is actually there before quoting, because a certified door fixed into unsuitable substrate is a certificate with nothing behind it.

Fire shutters in residential basements

Basement parking under an apartment block is a compartment, and the shutter between it and the rest of the building is frequently a rated assembly that the body corporate does not know it owns. We identify what is fitted, test it, and tell the trustees plainly what they have.

Fire shutter inspection and testing

Rated doors need testing at least every six months, and on coastal buildings that interval matters. We test, record and issue a report you can hand to an inspector, an insurer or a managing agent.

What a fire-rated roller shutter door costs in Cape Town

More than a standard door, because the rating is in the whole assembly and in the certification. We quote the door, the release interface and the commissioning separately.
