PROGrid™
Molded Grating
Proven corrosion resistance is just one of the benefits of our PROGrid™ molded grating. It’s strong, lightweight and performs reliably for years, even in extreme conditions. It also provides excellent slip resistance for worker safety.
Simple Installation
Grating can be fabricated using standard tools.
Reduced Maintenance Costs
The high resin-to-glass ratio (approximately 65% resin to 35% glass by weight) provides a long service life, so you won’t have to replace it as often as other materials. And molded-through color eliminates painting.
Stock or Custom Sizes
Molded grating is available in stock panels, or we can fabricate to size to meet your specifications. We can also design, engineer and fabricate complete FRP systems.
Less Waste
Interwoven square mesh construction provides bi-directional strength, so you can cut grating to fit and make the most efficient use of each panel.
Dimensionally Stable
A low coefficient of expansion and contraction makes our grating dimensionally stable in many environments.
PROGrid™ Molded Grating
PROGrid™ molded grating is available in three standard resin systems, each providing a different level of corrosion protection. Choose smooth top, grit top (a quartz grit anti-slip surface) or meniscus top (which has a concave, half-moon cross-section).
