Fire-Rated Roller Shutter Doors in Bronkhorstspruit

• 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. Around Bronkhorstspruit the sites that need them are industrial and agricultural, and both carry a serious fire load.

Fire-rated roller shutter doors we supply in Bronkhorstspruit

• 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.

Fire risk on agricultural and grain buildings

A grain store, a feed store or a hay shed carries a fire load that most industrial buildings would envy, and grain dust in suspension will carry a flame front. Where a compartment line runs through an opening on that kind of building, the rated door is doing real work. It also has to survive years of dust before the day it is needed, which is why we test the release rather than looking at it.

Where else fire shutters are needed here

Manufacturing and processing buildings at Ekandustria where compartment lines cross openings. Fuel and chemical stores. Plant, generator and switch rooms. Any opening the fire design has marked as rated.

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.

Dust and the release mechanism

Out here the component most likely to have quietly failed is the release. Dust packs the mechanism, links seize and descent brakes that have never been exercised will not run. We operate the release fully at every test and report a seized one as a failure rather than an observation.

Installation of fire shutters

Fixings go into the rated construction to the tested detail, gaps at head and jambs are sealed with the correct materials, and release and descent are tested and recorded at handover. The documentation is handed over with the door.

Fire shutter inspection and testing

Rated doors need testing at least every six months, and more often in dusty conditions. The release must operate, the curtain must descend fully into its guides, and nothing must obstruct the drop. We test, record and issue a report you can hand to an inspector or an insurer.

What a fire-rated roller shutter door costs in Bronkhorstspruit

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 so the cost of compliance is visible.
