RHIDOOR compiled these new specification requirements so you can read a fire rated roller shutter quote with confidence. They split into steel shutter requirements and inorganic-fabric shutter requirements. The inorganic-fabric list below is what we apply on premium builds; the steel list follows the same discipline.
Fire Rated Shutter Specifications: Inorganic-Fabric Build
- Curtain fabric. Raw materials meet health and environmental rules, with no banned substances.
- Curtain face, drum, and fixings. Standard technical requirements apply to each.
- The inorganic composite curtain face must not wrap the drum directly. It links through fixings.
- Rails and embedded steel. Rails fix firmly on site; embedded steel sits 600–1000 mm apart. On vertical shutters, rail verticality error against the base stays at or under 1.5 mm per meter and 20 mm over full length.
- Lintel and embedded steel. Fitted firmly, with embedded steel 600–1000 mm apart.
- Bottom bar. It runs parallel to the floor with even contact, and its stiffness exceeds the curtain face with a firm connection.
- Drive. Sprockets, chain, and bearings built to spec. Roller chain and sprocket dimensions and tolerances follow standard chain specs; static strength and the chosen safety factor stay above 4. Drive, bearing, and chain surfaces are free of rust, with proper lubricant. On a vertical shutter, drum deflection in normal use stays below 1/400 of drum length. A side-coiling shutter drum stands perpendicular to the base, with verticality error below 1.5 mm per meter and below 5 mm over full length.
