Pultruded FRP cover plates (玻璃钢拉挤盖板) are ribbed, corrosion-resistant panel covers manufactured by continuous pultrusion — widely used as walkway and platform covers, tank and channel covers, and trench covers at water and wastewater treatment plants and other industrial sites.
Why pultruded FRP covers
- More scientific structural design — ribbed underside for load support without adding weight.
- Easier on-site installation — lightweight compared to steel or concrete covers.
- Long spans — suitable for spans of 5 meters and above.
- Corrosion resistance — unaffected by water, chemicals and outdoor weather exposure.
- Multiple color options — available in yellow, blue, green, and gray to match site or safety requirements.
