Machs isn’t just a molded FRP grating supplier — we also fabricate our products so you can rest assured that you get the best product customized to your specific application. We take great pride in quality control for our products. If you would prefer to fabricate your molded grating, refer to the following procedures:

Safety precautions: When cutting Molded grating, always wear safety goggles to protect your eyes and a dust mask to reduce dust inhalation. Also wear gloves and a shop coat with neck and sleeves taped to prevent skin irritation. Work in a well-lighted and ventilated area.

Cutting molded grating: Depending on the amount (linear feet) of grating to be cut, a variety of shop tools can be used. For best results, use a heavy-duty rotary saw with a masonry, carbide or diamond coated blade. Firm support of the panels will prevent shifting. Turning the panel bottom-side-up gives a smooth surface for the saw to ride on and reduces chipping. Be sure to allow for the blade kerf (3/16″) when measuring.

Grinding: All cut edges should be ground smooth. Use a coarse grit, open coated (resin) grinding disk.

Finishing: All cut surfaces should be coated with resin to prevent corrosion of glass fibers. A light coating of two-part resin system or urethane spray paint is satisfactory.

Installation: Provide for a minimum of 1-1/2″ support around all panel edges. Use type “M” stainless steel (type 316) clips every 48″ (maximum) for full 4′ x 12′ panels, a minimum of four clips for any piece.

Molded fiberglass grating is manufactured in a one piece construction process by interlacing pre-wetted glass reinforcing strands in a liquid resin matrix within a given configuration. Once the resin matrix has cured, the molded grid is removed from the mold. The one piece construction insures that all glass is impregnated with resin.
