The original, heavy duty, 10-point locking steel security doors.
Kirncroft Korestrength® steel doors offer the optimum mix of high build quality, high material specification and high-quality hardware for an excellent price.
High-security locking system.
Having been subjected to over 20 years of real-world development, you can be sure that our custom 10-point locking system 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.
High-specification material selection.
Constructed using 1mm galvanised steel for the door skins, 2mm galvanised steel for the frame, 1mm galvanised steel for the subframe and 10mm galvanised steel rebar reinforcements. Our 10-point locking doors never fail to impress when resisting physical attacks.
Polyurethane-injected foam insulation to both the door and frame means that our doors offer high-performance insulation values and add to the door leaf’s strength and rigidity.
We offer a two-year warranty as standard.
Designed with containers and modular buildings in mind.
Designed with tolerances that allow for “racking”, our products work seamlessly with modular and container builds.
