Classic Case Study: San Francisco Café Entrance
A brick-and-steel entrance upgraded with Ninja Deterrent™ anti-climb spikes, combining timeless aesthetics with uncompromising perimeter security.

Concept: Brick × Steel Contrast
The historic warmth of brick is paired with the industrial precision of steel framing. To complete the composition, Ninja Deterrent™ spikes were introduced, ensuring this café entrance is not only stylish but also fully protected against intrusion attempts.
Security Meets Design
Above the beam, a continuous line of Ninja Deterrent™ anti-climb spikes provides decisive protection. Their low-profile design allows the spikes to disappear visually into the architecture, while still delivering the proven deterrence that Ninja Deterrent™ is known for in high-end residential and commercial projects.




Adding Warmth with Greenery
Planters soften the industrial edge of brick and steel. While greenery creates a welcoming touch for customers, Ninja Deterrent™ continues to provide hidden strength above — ensuring the atmosphere remains inviting yet secure.
