Product Overview
FRP pultruded grating is a plate with gaps made by using FRP pultruded "l" shaped profiles as load-bearing bars, pipes and rods as connecting rods, and through certain assembly processes.
Product application fields
FRP pultruded grating is applied in fields such as water treatment, water supply and drainage, chemical and petroleum, power, papermaking, engineering construction, textile, printing and dyeing, and shipping.
Specific applications: operation platforms, stairways and walkways, stair railings, floors, manhole covers, walkways, pedestrian Bridges, equipment safety railings, scaffolding.
Product features
Pultruded FRP grating possesses most of the characteristics of molded FRP grating, but it also has significant differences. The most important one is the high glass fiber content (65%-70%) in the load-bearing bar direction. Therefore, compared with molded FRP grating, it shows more advantages when used in large spans, which will reduce the foundation support and lower the engineering cost.
Light weight: Pultruded grating weighs only about a quarter as much as steel, making it very easy to handle and thus reducing handling costs.
High strength: Pultruded grids offer a very high strength-to-weight ratio, with approximately 35% resin and 65% glass fiber by weight.
Uv resistance: Pultruded grating is formulated with UV absorbers and polyester surface felt to achieve the best UV resistance effect.
Flame retardancy: It has a flame retardant effect of grade 1 25 or an oxygen index of 26 or above. (As required by the project)
Chemical resistance: The selection of high-quality orthophthalic, isophthalic, vinyl ester resins and pultruded FRP grating with surface felt has excellent properties
Corrosion resistance.Other outstanding properties: impact resistance, maintenance-free, easy to process, anti-slip safety, insulation and heat preservation, etc.
