We produce the grating by two different processing way. One is molded grating, another is pultruded grating.

Molded grating is manufactured in an open, heated mold that resembles a large waffle iron. E-glass fibers are placed in the mold and completely wetted out with the resin. Many types of mesh sizes can obtain as per.

Different molds design. The molded grating were designed to provided safe, long-lasting and economical and worry-free solutions in enviroments where chemicals and other corrosive materials attack and destroy metal.

Pultrusion is a continuous molding process using fiber reinfrocements wit thermosetting resin matices. Typical resin included polyester, vinyl ester and phonolics. The wet-out fiber is formed to the desired geometric shape and pulled into a heated steel die. Most any constant cross-section can be pultruded.

The feature of pultruded GRP gratings consists of the fact that the glass to resin ratio is higher in the bearing bar direction, therefore the span capacity is higher than compared to that of the molded grating.

Our mesh system is different your iron grating, the common mesh size contain 38x38mm by 38mm thick, 38x38mm by 25mm thick, 50x50mmby 50mm thick, 100x25mmby 25mm thick, 100x38mm.
