Pultruded grating is produced using a pultrusion process involving a die. In this technique, continuous glass fibers are pulled through a resin bath, where they become impregnated with a thermosetting resin (commonly polyester, vinyl ester, or phenolic). The resin-soaked fibers are then drawn through a heated die, where they are cured and shaped into the desired grating profile, often characterized by a grid or lattice pattern. The resulting pultruded grating exhibits exceptional strength, corrosion resistance, and a lightweight design. This method is particularly suitable for heavy-duty applications and environments requiring high-performance grating.
