Swing security doors

Swing security doors are hinged steel doorsets tested to LPS 1175 for forced entry and, where needed, to LPS 2081 for stealth attack. ArxBridge supplies and installs single and double leaf swing systems across the UK for entrances, corridors and secure rooms. They are part of the wider security range.

What swing security doors are

A swing security door is the familiar hinged doorset, engineered to a forced entry rating. The swing action suits the openings people use every day: main entrances, corridor doors, office doors and plant room doors. Because the door moves on hinges, the hinge edge and the lock edge both sit inside the tested attack zones.

Ratings run SR2 to SR5 to LPS 1175. Where the threat is quiet attack, LPS 2081 applies instead: SRB resists three minutes with stealth tools, SRA one minute. A swing doorset can carry an LPS 1175 rating, an LPS 2081 rating, or both, depending on the threat. The LPS 1175 guide and the LPS 2081 guide explain the two standards.

The hinge edge is an attack edge. On a swing door, hinges are tested hardware, not ironmongery. Anti-lift hinges rated with the doorset stop the leaf being lifted off once the pins are attacked.

Picking the rating for swing security doors

Choose LPS 1175 where the attacker does not care about noise, and LPS 2081 where stealth is the method: museums, galleries and occupied buildings at night. Many swing doorsets carry both ratings, covering the loud and the quiet attack in one assembly.

How swing doorsets are built

The leaf is a steel shell, reinforced at the lock case, hinge edge and meeting stile. Double leaf versions add a tested meeting stile with interlocking edges and shoot bolts or multi-point locking tying both leaves to the frame. The frame is a steel section anchored to the wall, with the fixings inside the test scope.

Hinges are the critical hardware on a swing door. They carry the leaf weight, resist lift-off attack and sit within the tested assembly, so they cannot be swapped for standard hinges later. Locking is multi-point on SR3 and above. Closers, where fitted, are specified to the leaf weight and the rating; a closer that slams a heavy leaf out of alignment will defeat the door faster than any tool.

Combining swing security doors with other ratings

Swing doorsets combine readily with fire ratings: the assembly is tested to EN 1634-1 and LPS 1175 together (see fire and security doors). Forced entry and stealth attack can be combined in one leaf, covering both LPS 1175 and LPS 2081 threats. Where the swing door sits on an escape route, panic hardware to the correct standard is integrated without breaking the security rating.

On sites with a vehicle threat at the boundary, swing entrance doors work behind tested gates and barriers (see security gates). For ventilation through a rated swing door, see blast resistant louvred doors for how louvres are handled in rated leaves. Name each rating at quote stage.

Where swing security doors are used

Hospitals use rated swing doorsets on pharmacies, records stores and plant rooms (see healthcare). Transport hubs rate back-of-house doors, staff entrances and equipment rooms (see transport hubs). Offices, schools and public buildings use them wherever a corridor or entrance needs more than a standard commercial door. The swing format fits any opening that people pass through daily.

What sets the cost and lead time for swing security doors

Leaf size and weight drive the engineering: tall or wide swing leaves need heavier sections and more hinges to stay true. The rating sets the steel content and the test evidence behind it. Double leaf costs more than single leaf because the meeting stile is a second tested interface. Hardware grade follows: high-security cylinders, multi-point locks, closers and access control each add supply time.

Glazing, panic hardware and special finishes extend the programme further. Site work matters too: replacing a swing door in a live corridor may need out-of-hours working, and the frame anchorage depends on the wall construction found on survey. No prices are published; the quote follows the schedule.

How to specify swing security doors

1. Name the standard and rating. For example “SR3 (C5) to LPS 1175” or “SRB to LPS 2081”, per door.
2. Fix the leaf layout. Single or double leaf, handing, and clear opening width.
3. Set the hardware. Hinges, locks, cylinders, closers, panic hardware and access control.
4. Confirm fire needs. If the door sits on a fire compartment line, state the E or EI minutes too.
5. Send the schedule. Openings, quantities and site location are enough for a firm quote.
