Fire Rated Roller Shutter: Installation Notes On Site

Fitting a fire rated roller shutter is work for a maker-trained installer, not a general contractor. When you buy from a maker, the install and the after-sales repair usually come as one package. RHIDOOR is one such full-service supplier — we give on-site guidance, not just a product, and the fire shutter install notes below are the points our own crew checks on every job.

Curtain Slat Install

Linked steel fire slats must swing freely. Tilt one 90° and it should not drop out.
After assembly the steel slats must sit straight, with no holes or gaps.
End baffles and anti-shift parts must be firm. While the curtain travels, the shift between neighboring slats stays under 2 mm.
Inorganic fiber composite curtains need wind hooks at both ends.
The composite curtain links to the shaft through fixings, not a direct wrap.

Rail Install

The depth the curtain sits into the rail follows the spec table. When rail spacing passes the table value, add 10 mm of embed depth per end for every extra 1000 mm, and the shutter must not deform after fitting.
Rail tops curve into an arc and run long enough for normal travel.
Rail sliding faces stay smooth and straight. Slats or rollers run steady with no bang or catch.
On a single-curtain shutter the two rails stay parallel; on a twin-curtain model the paired curtains also stay parallel. Parallel error stays under 5 mm.
After fitting, rail vertical error against the base stays under 1.5 mm per meter and under 20 mm overall.
The smoke seal meets the curtain evenly and tight. It covers at least 80% of the rail length.
Rails fix to the building structure with embedded bolts, welds, or expansion bolts. Fixing points sit 600–1000 mm apart.

Bottom Plate Install

The seat plate runs parallel to the floor with even contact and a firm link to the slats or curtain.
An inorganic composite seat plate lets the curtain drop smoothly with the right sag.

Lintel Install

The lintel is firm, with fixing points 600–1000 mm apart.
The smoke seal in the lintel meets the slat or curtain face evenly and tight. It covers at least 80% of the lintel length, and any gap in the unsealed part stays under 2 mm.

Drive Unit

The shaft and bracket plate fix firmly to concrete or embedded steel.
In use, shaft deflection stays under 1/400 of the shaft length.

Shutter Motor

Fit the motor per the manual, firm and reliable.
The motor carries a manual chain and a manual quick-release, placed within easy reach and clearly marked. It must not be locked, and it is built from non-combustible or hard-to-burn material.

Protection Box

Box size matches the opening width and the rolled shutter size, and leaves a gap from the cover when full so nothing clashes.
Leave a service opening near the motor.
The box fire rating must match the shutter.

Controller

The controller and the manual button box mount on both inner and outer walls. If one side is unmanned, mount on one wall per the design. Both stay easy to spot and mark up, down, stop.
The controller and button box are firm, with their base 1.3–1.5 m above the floor.
Metal parts carry a ground point with a clear mark, and the ground screw serves no other fastening.

Fire Rated Roller Shutter: Closeout Checks

The thermal release device sits where the design and manual show. Seal every gap between the shutter, the box, the floor, beam, wall, and column with fire-stop material. The fire-stop seal must meet the same fire-resistance level as the shutter.
