- Rapid Deployment Technology: Tool-free clamps assemble 1m² in under 2 minutes with interlocking joints requiring no welding/bolting. Adjustable feet provide ±150mm height compensation for uneven ground.
- Unmatched Durability: Features reinforced bearing bars (8mm thick) that survive forklift impacts, zinc-aluminum coating that resists concrete slurry corrosion, and operational range from -40°C to 120°C.
- Safety Engineered: Grit-embedded surface (0.8mm roughness depth) with 100% fall protection at joints (tested to EN ISO 14122).
| Application | Solution | Benefit |
