Metal sculptures, often displayed in public spaces, are vulnerable to theft and vandalism. To prevent such incidents, artists and installers employ several anchoring and security techniques.

1. Concrete Foundations: Heavy sculptures are often embedded in deep concrete bases, making them difficult to remove without heavy machinery. The foundation may include steel rebar for added stability.

2. Specialized Fasteners: Tamper-resistant bolts, epoxy adhesives, or welded brackets are used to affix sculptures to their bases. These fasteners require unique tools for removal, deterring casual thieves.

3. Ground Anchors: For larger installations, underground anchors or steel rods are driven deep into the soil, providing a secure hold.

4. Surveillance and Lighting: Placing sculptures in well-lit areas with CCTV cameras reduces the risk of vandalism.

5. Anti-Climbing Measures: Spikes or smooth surfaces can prevent unauthorized access to elevated sculptures.

By combining these methods, metal sculptures can remain safe and intact for public enjoyment. Regular maintenance and community engagement further enhance protection efforts.
