Armored glazed door RC3 to RC4, P4A to P8B or bullet-resistant BR3 to BR4
Specializing in security doors, Bünkl designs, manufactures and markets a complete range of RC3-RC4 burglar-resistant doors (according to EN 1627-1630) in single or double leaf versions.
This range is designed with a leaf and frame made of double 20/10 EZ steel sheet, a material that provides sufficient mechanical resistance against forcing and drilling tools. It will effectively protect your technical areas and sensitive premises. It can be fitted with single or double glazing for outdoor use and equipped with a choice of a multi-point mechanical lock with automatic bolt ejection or a motorized lock for access control.
With its expertise in manufacturing, Bünkl offers these RC3-RC4 doors in standard or custom sizes, in single, double, or asymmetrical double leaf versions. For double doors, the identically designed semi-fixed leaf is fitted with a square fire engine bolt. We sell the SDx Glazed door range with mechanical and electric locks from the following brands:
- Dény Security
