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 spikes installed at an apartment entrance in San Francisco, enhancing building perimeter security.
Apartment Entrance | San Francisco
The refined cream-colored exterior is enhanced by the wrought iron gate and Gothic Dual Ninja Deterrent™ anti-climb spikes, achieving a subtle and effective security solution.
Background and Design Intent
Nestled in a quiet residential area, this apartment features classical molding, an arched gate, and a textured exterior. The client wanted to enhance the security around the entrance without compromising the building's historical atmosphere. Therefore, a decorative wrought iron gate was adopted, and Ninja Deterrent™ spikes were installed in a continuous line above the arch. This configuration is low-profile yet strongly deters access to the balconies and windows.
Against the warm white exterior, the wrought iron design tightens the Ninja Deterrent™ spike line, giving the overall impression a beautiful, cohesive look.
Balancing Security and Decoration
The sharp, linear lines of the Ninja Deterrent™ are compatible with the gate's scroll decorations and the classical cornice above. By finishing the spikes in matte black, they become an integrated architectural detail.
Continuous Ninja Deterrent™ spikes - subtle in appearance, uncompromising in performance.
A sense of rhythm - a light appearance with sharp deterrent power.
Circulation and Lighting
Beyond the gate is a staircase leading to the upper floors, The architectural design of the entrance allows natural light to enter easily. After sunset, compact floodlights ensure visibility and enhance the deterrent effect. The Ninja Deterrent™ spike line increases the safety of the intermediate landing while being positioned so as not to obstruct the view.
The Ninja Deterrent™ line tightens the key points against the decorative plaster on the arch.
