Strong, Reliable and Ready to Fit
When a single door is not enough to secure a wide opening, double security doors are the answer. At Quality Steel Doors, we supply heavy-duty double steel security doors that are built to protect commercial and domestic properties across Ireland and GB. These doors are tough, practical and designed to keep intruders out.
The Double Security Door from Quality Steel Doors is made from 2.0mm pre-lacquered Zintec steel with a powder-coated finish. Each door leaf hangs on four heavy-duty lift-off hinges that provide strong support and make installation straightforward. The door is supplied in three parts for easy transport: two door leaves and the frame. This keeps delivery simple and reduces the risk of damage in transit.
An Expandable Frame That Fits Your Opening
One of the best features of this product is the expandable steel door frame. Not every building has the same sized opening, and that can cause problems with standard fixed frames. Quality Steel Doors solves this with a frame that adjusts to fit structural openings between 1780mm and 1840mm wide and 2075mm high. This means fewer headaches during fitting and a cleaner, tighter result once installed.
The frame is made from 2.0mm thick cold-rolled steel and comes with a full pre-fitted weather seal on all sides. A stainless steel threshold is also included and can be removed if needed. Two anti-jemmy hinge bolts per door leaf add extra resistance against forced entry, making these double security doors a solid choice for warehouses, garages, offices and outbuildings.
A Locking System Built to Resist Attack
Security is only as good as the lock behind it. Quality Steel Doors fits a 7-point locking system into these double steel security doors as standard. The active leaf features two shoot bolts into the top of the frame, while the inactive leaf comes with its own built-in shoot bolts. A drill proof lock mechanism is pre-installed, meaning the lock body can withstand drilling and impact attempts. This gives property owners confidence that the door will hold firm under pressure.
A stainless steel handle and dead bolt lock complete the setup. Everything is fitted before the door leaves the factory, so there is no need to source extra hardware. Quality Steel Doors makes it simple to get a fully functioning, high-security entrance straight out of the box.
Practical Details That Matter
Quality Steel Doors understands that buying double security doors is an investment. That is why every detail has been thought through. The doors are priced at £600 plus VAT and delivery is available across Northern Ireland, the Republic of Ireland and the UK. Up to two double doors can fit on a single pallet, which helps keep shipping costs down.
For those who want a more personalised look, Quality Steel Doors offers a powder coating service so the doors and frame can be colour-matched to your building. Vision panels with Georgian wired polished plate safety glass and louvre panels for ventilation are also available on request.
