Structural Design Features
1. Ribbed Anti-Slip Surface
- Both faces are grooved in a cross-hatch or chevron pattern.
- Ensures high friction coefficient and prevents movement under dynamic load.
- Ideal for polished concrete or metal bases in workshops, plants, and hospitals.
2. Reinforced Internal Layer (Optional)
- Galvanized steel mesh reinforcement (0.8mm thick) for extra compressive stability.
- Recommended for high-load applications such as engine test benches or press machines.
3. Precision Vulcanization
- Controlled curing under high pressure ensures consistent Shore hardness.
- Homogeneous molecular bonding eliminates weak zones and ensures dimensional accuracy.
4. Load Distribution
- Evenly spreads machine load over a large contact area.
- Prevents point stress on concrete floors and extends both pad and floor life.
