FRP Gratings
High-performance, corrosion-resistant fiberglass reinforced plastic gratings for demanding industrial environments.
Superior Alternative to Traditional Metal Gratings
Kelvin Composites FRP gratings are engineered to provide superior performance in harsh environments where traditional metal gratings fail due to corrosion, weight constraints, or electrical conductivity concerns.
Our FRP (Fiberglass Reinforced Plastic) gratings combine high-strength fiberglass with premium resins to create a grating system that offers exceptional durability, corrosion resistance, and low maintenance requirements—all at a lower lifetime cost than traditional materials.
Types of FRP Gratings We Offer
Molded FRP Gratings
Manufactured using a compression molding process, our molded FRP gratings feature a one-piece construction with an interlocking design that provides bidirectional strength and superior corrosion resistance.
- Available in multiple mesh configurations: 38×38mm and 25×25mm
- Standard panel sizes: 3660×1220mm, 4000×1000mm
- Depths: 25mm, 30mm, 38mm, 50mm
Pultruded FRP Gratings
Manufactured using the pultrusion process, these gratings feature continuous unidirectional bearing bars for exceptional strength in the span direction, making them ideal for heavy-duty applications.
- Bearing bar spacing: 25mm, 30mm, 38mm, 40mm
- Standard panel sizes: 3660×1220mm, 4000×1000mm
- Depths: 25mm, 30mm, 38mm, 50mm
