Modular building steel door
Suitable for applications where weight is essential, our modular building steel doors offer durability and strength at only 47 kg!
Kirncroft modular building steel doors have a fully galvanised steel construction and come with a powder coat finish in white. In addition, the integrated cloaking frame gives a 30mm rebate to the top and sides of the door frame, facilitating quick and simple fitting into modular wall panels.
With a 1mm galvanised steel subframe and Kirncroft heavy-duty hardware as standard, a lightweight door needn’t be light on quality.
Frame size – 910x2065mm

Light on weight. Heavy on quality.
Our modular building door weighs only 47kg. However, it still features a 1mm galvanised steel subframe, a stainless steel threshold, Kirncroft heavy-duty hinges, and a Kirncroft high-security mortice lock and cylinder.
Designed for applications where weight is an essential factor.
Designed with tolerances that allow for “racking”, our modular building steel doors are suitable for timber framed units, towed units, cabins and other lightweight structures.
Our modular building doors are available in stock with a white powder-coat finish.
Integrated cloaking frame.
With an integrated cloaking frame that gives a 30mm overlap on the outer face, Kirncroft modular building steel doors automatically make-up to flat panel units.
High-security locking system.
Having been subjected to over 20 years of real-world development, you can be sure that our custom mortice lock will perform when it matters.
“Better than 1*” Kitemarked lock cylinder as standard.
We tested a 1* Kitemarked cylinder in-house, and we felt it wasn’t good enough, so we made some improvements.
We offer a two-year warranty as standard.
