About the S6es Aluminium Door Series
Tailored security solutions with design freedom
The S6es series by SYSTEM SÄLZER® offers premium aluminium doors that balance visual elegance with uncompromising security. Designed for high-risk applications, these doors are flush-mounted, structurally reinforced, and visually seamless with surrounding façade systems.
Each door is tested and certified for resistance to forced entry (RC4), bullet attack (FB4-NS), and explosions (EXR2), while maintaining performance in wind load, water tightness, and thermal insulation. Customisable options allow the doors to integrate effortlessly into both residential and commercial environments.
Available as single or double-leaf doors, inward or outward opening, the S6es system accommodates diverse architectural needs and usage types. With compatibility across all SÄLZER® components, it’s the ideal choice for projects requiring unified aesthetics and robust protection.
