Corrugated Metal Side Gate | Arizona
Classic Shinobi Gaeshi black steel security spikes installed on a rustic corrugated metal side gate in Arizona, blending desert aesthetics with anti-climb protection.
Anti-climb security measures installed at a luxury condominium in San Francisco, enhancing building security while preserving the upscale appearance.
Luxury Condominium | San Francisco
Integrating Ninja Deterrent™ Gothic Dual to assess a hidden weak point onto a custom gate for a narrow service passage. We elevated the perimeter security without compromising the sophisticated appearance of this luxury residence. The combination of a robust stainless steel frame and a tense spike line ensures both the safety and elegance of the passageway.
Context and Design Overview
The project site is a service passage located in an urban block surrounded by high-rise buildings. This inconspicuous location presented a unique security vulnerability, requiring the client to demand a robust anti-climb function and reliable deterrence day and night. By integrating Ninja Deterrent™ onto a rigid stainless steel frame and mesh panel, we created an unobtrusive yet highly effective defense line.
Mesh + Warning Sign: Assurance for residents, warning for intruders.
Materials and Finishes
Hairline-finished stainless steel was selected for the frame and gate components to ensure durability and architectural harmony. The Ninja Deterrent™ spike rails are perfectly aligned with the top edge of the gate, ensuring uncompromising protection while functioning as a sharp design line.
**Ninja Deterrent™ Spike Line:** Subtle from afar, a decisive deterrent up close.
Security Integration
The mesh infill ensures visibility, reduces blind spots, and eliminates footholds. Combined with Ninja Deterrent™ spikes and clear security signage, this provides both physical and psychological deterrence.
**Fusion of Security Camera and Ninja Deterrent™:** The coverage of the surveillance camera and the placement rhythm of our product as a single system.
Key Specifications
- Frame: Stainless steel with a luxurious crown finish.
- Infill: Steel mesh that enhances visibility and eliminates footholds.
- Ninja Deterrent™ Spikes: Continuous spike-line along the top of the gate.
- Hardware: Heavy-duty hinges, latches compatible with access control systems.
