　　Crossed spiral razor wire, also known as screw-type or coiled razor tape, is a formidable and highly cost-effective passive security barrier designed to deter and delay intrusions over the tops of walls, fences, and gates. It consists of a core wire wrapped with continuous, sharp, stainless steel razor blades, formed into a large, spring-like coil. The "crossed spiral" configuration involves two coils that are interlinked and mounted together, creating a dense, rotating mass of blade edges that is extremely difficult to compress, climb over, or penetrate with tools.

　　Its effectiveness lies in its intimidating physical presence and its practical defensive properties. The overlapping, rotating coils offer no stable footholds or handholds. Any attempt to climb or breach it results in severe lacerations. It acts as a powerful psychological deterrent, visibly signaling a high-security area. Compared to installing taller fences or walls, adding razor wire to an existing perimeter is a relatively low-cost upgrade that significantly enhances security levels, making it a staple for prisons, military installations, warehouses, industrial plants, and sensitive infrastructure.

　　Installation is typically straightforward. The coiled units are stretched along the top of a wall or fence and secured at intervals with heavy-duty brackets and bolts. The crossed spiral design provides stability and prevents the coils from being easily pushed apart. It is often used in conjunction with other security measures like CCTV and lighting. While offering minimal visual appeal, its primary purpose is uncompromising security. Modern versions use high-quality, galvanized, and stainless steel materials to ensure long-term performance with resistance to corrosion.

　　For situations where budget constraints exist but a substantial upgrade in perimeter delay is required, crossed spiral razor wire delivers exceptional value. It transforms an ordinary fence into a serious obstacle, buying valuable time for security responses. While not appropriate for all environments due to its hazardous nature, in high-risk security contexts, it remains one of the most efficient and economical ways to fortify a boundary against determined intrusion attempts.
