To understand the differences between molded and pultruded grating, it is important to know exactly what Fiberglass Reinforced Plastic (FRP) is. FRP is an alternative to traditional industrial materials, such as steel, concrete, and wood. It is made by combining resin with fiberglass. Resin formulations, resin proportions, and manufacturing techniques allow this product to be used as gratings, handrails, ladders, platforms, and custom engineered solutions. Often people ask, “What is the difference between molded and pultruded grating?” Fibergrate wants to help people make the right decision when it comes to choosing the right material for their next project. Some people might simply say: “Molded grating is a panel that has a square or rectangular top mesh whereas pultruded grating is composed by a series of parallel bars.” Is it really this simple? Please allow us to explain.
The Reversing Falls are a unique and beautiful phenomenon created by the collision of the Bay of Fundy and the Saint John River in New Brunswick, Canada. At low tide the river empties into the bay causing a series of rapids and whirlpools, a truly natural spectacle.
One of the largest offshore oil platforms is currently being built, and it requires around 250,000 square feet of grating. Offshore oil platforms have a list of environmental factors that must be considered when selecting materials. The salty ocean air makes for an extremely corrosive environment. The slippery conditions cause their own unique set of safety concerns, and the risks of fires need to be kept in mind. While these are all important factors, perhaps the driving factor in deciding materials is the weight requirements.
When deciding which company to contract for the fabrication and installation of grating on one of the largest offshore oil platforms that has ever been built, a customer realized he already knew the right choice.
Did you know corrosion is the third largest cost for Americans, only to be preceded by real estate and healthcare? Why should this even be? Many applications could utilize corrosion resistant materials, saving the economy money and, more importantly, lives.
Wastewater and Water treatment plants historically used grating, stair treads, railing, ladders and structural platforms made from traditional materials (steel, galvanized steel, aluminum and wood). The popularity in these materials is not driven by the product that would provide the safest or longest lasting service life but the availability and initial product cost. While these traditional materials have been used in wastewater plant applications over 100 years, fiberglass reinforced plastic (FRP) products have only been available for nearly five decades
