What Are the Different Types of FRP Grating and Which Is Right for You?

FRP (Fiber Reinforced Plastic) grating is a grid-like sheet made of resin and glass fiber through molding and pultrusion processes. It has the characteristics of flexible and customizable performance, corrosion resistance and durability, non-magnetic, insulation and safety, and can be used in various industrial and commercial applications. Understanding the different types of FRP grating is essential to choosing the grating that suits your specific needs.

Molded FRP Grating

Molded grating is produced in a single-piece construction, offering exceptional strength and corrosion resistance. Its open grid structure ensures optimal drainage and airflow, making it ideal for environments exposed to moisture or chemicals, such as wastewater treatment plants or chemical facilities. This type is also lightweight and easy to install, making it a practical choice for walkways and platforms.

Pultruded FRP Grating

Pultruded grating consists of individual bearing bars and cross rods assembled for high load-bearing capabilities. It is suitable for applications requiring greater spans, such as heavy-duty platforms or bridge decks. Pultruded grating provides strength and stability without adding significant weight.

Covered FRP Grating

This grating has a solid top layer, offering a slip-resistant surface for added safety in areas with heavy foot traffic or moving equipment. It is commonly used in food processing facilities or industrial settings where spills are frequent.

Which Is Right for You?

Your choice depends on the application. For corrosive environments, molded grating is ideal. For heavy loads, pultruded grating excels. For safety and cleanliness, covered grating is the best fit. By understanding the unique properties of each type, you can select the perfect FRP grating for your project.
