Security Door

Security doors can be fitted with a range of locking options depending on the level of resistance required. Common choices include a five-lever mortice deadlock, euro cylinder with anti-snap features, and multi-point locking systems that engage at the top, bottom and hinge side when the handle is lifted. Multi-point locking is particularly useful on a door in everyday use, as it spreads the locking force across several points of the frame rather than a single latch.

Yes. Vision panels and perforated mesh sections can be incorporated into the door design. The aperture is framed and reinforced within the door leaf, and any grille or mesh used is welded or mechanically fixed into the door structure rather than simply bolted on. This lets light through or allows you to see who is at the door without creating an obvious weak point around the opening.

Most security doors are supplied as a complete door and frame assembly. The frame is made to the measurements of your existing structural opening, and we discuss exact dimensions and tolerances with you before production. In some cases the existing timber frame can be retained and the steel door hung within it, but this depends on the condition of the current frame and the weight of the door.

A security door is a full door leaf with its own frame, hinges, threshold and lock, designed to be the primary door for that entrance. A gate across a doorway is typically an open-barrier style addition fitted in front of or behind an existing door. A security door is generally weather-sealed and insulated to a degree, whereas a gate is primarily a physical barrier and may leave the existing door doing the work of keeping out weather.

Security doors are fitted with heavy-duty steel or stainless steel hinges, and the number of hinges is matched to the door weight and size. Doors can be made left-hand or right-hand hanging to suit your opening. If you are replacing an existing door, tell us which side the hinges are on when viewed from outside, and we will set the door up to match.

Yes, the frame includes a threshold section, usually an aluminium or steel profile. The door leaf can be fitted with a drop seal or rubber compression seal at the bottom edge. This is important on a front or side entrance where you want to stop draughts and water while keeping the threshold low enough for everyday foot traffic.

Security doors are normally manual because they are used as the primary entrance door and are opened and closed many times a day. In principle a door could be fitted with an electric strike or access-control release, but a full swing automation kit is unusual for this product type. If you need automation, it is worth discussing the specific door and opening arrangement with us before ordering.

Steel security doors are supplied with a galvanised undercoat as standard, followed by a powder-coated finish. The standard colour is black, and other RAL colours are available on request, with popular choices including anthracite grey. The galvanised undercoat is the standard preparation layer for the steel before powder coating is applied.

A custom security door typically takes 2 to 4 weeks from order confirmation. After you place your order, we produce a drawing for your approval before production begins, so your confirmation of the drawing affects the overall timescale.
