- Despite these advantages, fiberglass shells also present challenges. They can be brittle under certain conditions and may require skilled labor for installation. However, ongoing research and development in composite materials are continually addressing these issues, promising even more robust and user-friendly solutions in the future.






3.Micro fiberglass grating
The corridor of the cellular fiberglass grating is lower than aluminum and steel, and it also corrosion resistance. The micro fiberglass grating especially useful for walking on the trolley and the wheelchair,the double layer micro grid can prevent the appearance of the grid and other objects.
National Grating Fiberglass Trench and Drain Grates are available in two standard resin systems. Each providing different levels of corrosion protection. Both resin systems meet Class 1 Flame Spread Rating per ASTM E-84 test standards.
