The innovative Glass Fiber Reinforced Brick Pallet (GMT Pallet) has become a key component in modern steam curing applications. Made from a high-strength composite of glass fiber and thermoplastic material, these pallets provide excellent load-bearing performance, heat resistance, and dimensional stability.
In steam curing rooms, when temperatures exceed 80°C, standard fiberglass pallets may gradually experience surface stress. In such cases, it is recommended to add steel edges to enhance rigidity, prevent corner deformation, and extend service life. For temperatures below 80°C, the standard GMT pallet offers sufficient strength and stability without steel reinforcement.
Compared with traditional wooden pallets, fiberglass pallets offer superior durability, lighter weight, and better performance in automated production lines. Many customers report that GMT pallets maintain smooth surfaces, resist moisture, and ensure consistent block quality even after years of use.
Performance Comparison: Glass Fiber Pallets vs Wooden Pallets
| Feature | Glass Fiber Reinforced Brick Pallet (GMT Pallet) | Wooden Pallet |
|---|---|---|
| Load-Bearing Capacity | High, suitable for heavy concrete blocks and fully automatic block machines | Low, prone to bending or cracking over time |
| Heat Resistance | High; standard version for <80°C, steel edges for higher temperatures | Low; may deform or crack under high heat |
| Dimensional Stability | Excellent; maintains precision after multiple curing cycles | Poor; absorbs moisture and changes size |
| Moisture Resistance | Excellent; does not absorb water, smooth surface | Poor; absorbs moisture, affecting demolding and block quality |
| Service Life | Long; over 8 years for standard, longer with steel edges | Short; typically 2–3 years, highly environment-dependent |
| Weight | Light; easy to handle and compatible with automation | Heavy; difficult to move |
| Maintenance Cost | Low; durable and easy to clean | High; frequent replacement and upkeep required |
| Corrosion Resistance | Excellent; does not rust or rot | Poor; prone to mold and decay |
| Production Efficiency | Improves vibration efficiency and automation performance | Can reduce efficiency due to instability |
Conclusion:
Choosing the right pallet depends on your steam curing temperature. For curing rooms above 80°C, use GMT pallets with steel edges for maximum lifespan. For standard temperature ranges, the standard fiberglass pallet is already reliable, offering excellent performance, reduced maintenance costs, and long-term value compared with wooden pallets.
