- In addition to their robust performance characteristics, FRP spraying pipes offer design flexibility
- In addition to their robustness, FRP pipes also contribute to environmental sustainability
- As technology progressed, coal mine tools underwent a transformation. The introduction of pneumatic machines in the 19th century revolutionized coal extraction. Devices like the pneumatic pick, powered by compressed air, significantly increased the speed and efficiency of coal cutting. This marked a shift from sheer human effort to mechanical assistance, reducing the physical strain on miners and paving the way for more substantial excavations This marked a shift from sheer human effort to mechanical assistance, reducing the physical strain on miners and paving the way for more substantial excavations

- Despite its intimidating size and noise, the rotary jackhammer is relatively easy to operate
- The primary purpose of a threaded drill rod is to transmit torque from the drilling machinery to the drill bit, allowing for efficient drilling into hard rock formations. The threads on the rod not only facilitate assembly and disassembly but also ensure a secure and stable connection, minimizing the risk of slippage during operation.
Fiberglass covered grating is corrosion resistant, low maintenance, and strong. This long-lasting fiberglass floor product combines a slip-resistant plate and fiberglass grating, manufactured with any of our resin systems. Our fiberglass covered grating is the ideal choice when a 100% covered flooring surface is needed. It is available with a plate which is bonded to molded or pultruded grating.










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.
