FRP / GRP Moulded Gratings

We are leading manufacturer of FRP Gratings. FRP / GRP Moulded grating is a new type composite material, which is produced from glass fiber as framework and reinforced resins, including unsaturated polyester, epoxy resin and phenolic resin.
Strong, lightweight, extremely excellent corrosion and rust resistance are best representative of FRP/GRP grating.
Nowadays, the FRP/GRP grating gradually replace the steel gratings in commercial and industrial plants as its outstanding chemical and mechanical advantages.
FRP / GRP Moulded grating is ideal for highly corrosive applications where larger open area gratings are required. Molded Grating is ideal for applications requiring extensive cut outs for pipe, duct and electrical penetrations.

Pultrusion Operation

Pultrusion is a manufacturing method used to make strong, lightweight composite materials. In pultrusion, material is pulled through forming machinery using either a continuous-roller method (as opposed to extrusion, where the material is pushed through dies). In fiberglass pultrusion, fibers (the glass material) are pulled from spools through a device that coats them with a resin. They are then typically heat-treated and cut to length. Fiberglass produced this way can be made in a variety of shapes and cross-sections, such as C sections.
