molded frp gratings are manufactured in a one piece construction which results in a bi-directionally strong product. This allows openings for piping or cables in the grating of up to 10” without any additional support required (may vary depending on grating depth and location of opening). During the molded manufacturing process, the continuous fiberglass rovings are completely covered in a high percentage of resin, 65% by volume. With this high resin content, molded gratings are the most chemically resistant gratings offered and are often used in caustic chemical environments without hesitation.
The selection of the resin option also depends upon the purpose of use. For the general purposes Orthophthalic Polyester is more suitable. Some other resin options are Vinyl Ester, Isophthalic Polyester (or ISO), Fire Retardant and USDA certified. All resin options are UV Resistant and are designed for different purposes and conditions.
Available in various colors and styles, such as green, yellow, grey, orange and various other custom colors, fiberglass grating is more appealing in look as well. To ensure the longevity of the product, color is permanently added to the resin formula. The color and style of the grating are decided, while keeping the safety hazards in account. Some of the most prominent industries that use fiberglass gratings are waste water treatment plants, food processing plants, aquariums, power plants, chemical plants, lift stations, plating shops and also plants with canning and beverage facilities.
