The Madoors USA Bulletproof Automatic Roller Shutter Door and Bullet Resistant Motorized Shutter Window is a ballistic steel and aluminum roller shutter system manufactured to European BR3 through BR7 ballistic standards and American UL 752 Levels 1 through 9 — providing certified bullet-resistant protection for building windows, door openings, and access points across the complete range of handgun, assault rifle, and high-powered rifle threat levels. All ballistic steel used in the system is approved and reported by authorized certification institutions. Motor systems use Siemens brand side drive motors with Italian worm-geared reducers. Every system is designed and manufactured to customer-specified project dimensions and carries a 2-year company guarantee.
TECHNICAL SPECIFICATIONS
Madoors USA Bulletproof Roller Shutter systems are available in ballistic steel and aluminum construction types, manufactured to the following certified ballistic protection standards.
European EN 1063 standards: BR3 — protection against .44 Magnum handgun rounds. BR4 — protection against 9mm submachine gun fire. BR5 — protection against 5.56mm assault rifle rounds. BR6 — protection against 7.62mm × 39 assault rifle rounds. BR7 — protection against 7.62mm × 51 NATO rifle rounds — the highest standard level, providing protection against the most powerful military rifle calibers in operational use.
American UL 752 standards: Level 1 through Level 9 — covering the complete range from 9mm handgun protection at Level 1 through to 7.62mm rifle protection at Level 8 and beyond at Level 9. Ballistic reports are provided for all certified levels between UL 752 Level 1 and Level 9, with intermediate levels including Level 3 for .44 Magnum, Level 5 for 7.62mm rifle, and Level 8 for sustained 7.62mm rifle fire all covered within the manufacturing capability range.
The shutter operates by turning and wrapping the ballistic steel or aluminum curtain onto the overhead drum on opening, and unwinding from the drum on closing — maintaining the ballistic integrity of the curtain throughout the full open and close travel cycle without mechanical joints, overlapping sections, or gap formations in the protection layer at any position in the travel. Motor drive uses Siemens brand side drive motors providing reliable, commercial-grade automated operation. Reducers are Italian worm-geared type, providing smooth, controlled drum rotation with the torque reduction required for heavy ballistic steel curtain weight management.
All systems are designed and manufactured to customer-specified project dimensions — with no standard size limitation — ensuring precise fit to any building window, door, or opening geometry without requiring structural modification of the surrounding wall or frame.
KEY FEATURES
BR3 to BR7 European Ballistic Certification
The full range of EN 1063 European ballistic protection levels from BR3 through BR7 is available within the Madoors USA bulletproof roller shutter manufacturing capability — providing certified protection against the complete spectrum of handgun, submachine gun, and military rifle threats from .44 Magnum through to 7.62mm × 51 NATO rounds. European EN 1063 certification satisfies government, institutional, and commercial security procurement specifications across all European and internationally aligned markets.
UL 752 Level 1 to Level 9 American Certification
The complete American UL 752 bullet resistance rating range from Level 1 through Level 9 is available, with ballistic test reports provided for certified performance at all intermediate levels between Level 1 and Level 9. UL 752 certification satisfies US government, banking, financial institution, and commercial security procurement specifications for certified bullet-resistant shutter and window systems across the North American market and internationally where UL certification is specified.
Ballistic Steel & Aluminum Construction Options
Two construction material options are available — ballistic steel and ballistic aluminum — providing selection flexibility based on the required protection level, weight constraints, corrosion resistance requirements, and aesthetic specifications of each project. Ballistic steel construction provides the highest protection-to-thickness ratio for the highest ballistic levels. Ballistic aluminum construction provides reduced weight for applications where curtain weight and drum load are constrained by the building structure or motor specification.
Authorized Institution Certification & Ballistic Reports
All ballistic steel and aluminum materials used in Madoors USA bulletproof roller shutters are approved and reported by authorized certification institutions, with ballistic test reports available for each protection level. These independently issued reports provide clients with verified ballistic performance documentation for procurement compliance, insurance, and security specification purposes — confirming that the protection level claimed is independently substantiated by real ballistic testing rather than manufacturer assertion alone.
Siemens Side Drive Motor — Proven Commercial Reliability
The Siemens brand side drive motor provides reliable, long-service-life automated operation with the commercial-grade performance of Siemens industrial motor technology — the same proven motor platform used across the Madoors USA automated door and shutter product range. Siemens motor specification provides clients with confidence in motor performance longevity and global availability of replacement parts and service support.
Italian Worm-Geared Reducers
Worm-geared Italian type reducers provide the high torque reduction ratio required for smooth, controlled rotation of heavy ballistic steel shutter curtains on the drum — preventing uncontrolled curtain speed during descent under gravity and maintaining consistent, smooth motor-controlled movement throughout the full travel range of heavy protection-level ballistic steel curtains.
Drum Wrap Operation — Continuous Ballistic Integrity
The drum-wrap shutter mechanism maintains the full ballistic integrity of the curtain throughout the complete open and close travel cycle — with the curtain wrapping continuously onto the drum without mechanical joints, lapping sections, or gaps forming in the protection layer at any travel position. This continuous integrity is the fundamental ballistic performance advantage of the drum-wrap roller shutter format over sliding panel and folding shutter systems where panel joints and overlaps create potential penetration paths.
Custom Project Dimensions — Any Opening Size
Every Madoors USA bulletproof roller shutter system is designed and manufactured to the customer's project-specific dimensions — covering any building window width and height, any door opening dimension, and any non-standard aperture geometry. Custom sizing ensures a precise fit without requiring structural modification of the surrounding opening or compromise in ballistic protection coverage at panel edges.
2-Year Company Guarantee
All Madoors USA bulletproof roller shutter door and motorized shutter window systems carry a 2-year company guarantee, providing client assurance of system performance and manufacturing quality across the initial operational service period.
