3.Key Advantages
1. Excavation Safety
Prevents Damage: Clearly marks buried utilities to avoid accidental strikes during digging.
Multi-Layer Detection: Combines visual cues (color) with electronic detection (RFID/magnetic).
2. Durable & Weatherproof
Concrete: Frost-resistant (300+ freeze-thaw cycles).
Plastic/FRP: UV-stabilized for 10+ years outdoors.
3. Easy Installation
Placement: Buried 100-300mm below surface, above utility lines.
Alignment: Grid patterns for easy mapping (e.g., every 5m along pipelines).
