Shaft Fire Doors
Shaft fire doors are the small, heavily used access panels of a building's service core. They close pipe risers, electrical shafts, meter cupboards and duct enclosures, and they are opened far more often than a normal corridor door because maintenance teams go through them every week. The engineering problem is therefore not size but durability: a light leaf that sags, a latch that stops engaging, or a closer that loses adjustment turns a compliant shaft into an open hole in the compartment line. Sets are made in steel, in small single and double leaf sizes, with the closing and latching hardware chosen for frequent service access.

Criterios de selección
- Choose hardware for frequent maintenance access, not for a corridor door duty cycle.
- Keep the leaf light enough that one person can operate it in a service corridor with tools in hand.
- Confirm the shaft wall construction: a block shaft and a drywall shaft need different frame fixings.
- Label the door with the shaft it serves; on a busy floor, mislabelled shaft doors are a real operational problem.
Preguntas frecuentes
- How small can a shaft door be?
- Sizes follow the shaft opening and the access required. Send the opening dimension and the factory will confirm the feasible leaf.
- Can it be a louvred door?
- Ventilated shaft doors are a separate specification with their own fire performance. It is confirmed against the compartment requirement.
- Does it need a closer?
- Self-closing is normally required for a fire door on a shaft. The closer type depends on the leaf size and the frequency of use.
- Is a lock required?
- Access control depends on the building's security regime; it is specified with the door so the hardware is compatible.
