FRP (Fiber Reinforced Plastic) walkways are durable, corrosion-resistant walking platforms made from composite materials, typically glass fiber reinforced with polyester, vinyl ester, or epoxy resin. These walkways are widely used in industrial, marine, and infrastructure settings where safety, low maintenance, and long service life are critical.

One of the key benefits of FRP walkways is their exceptional resistance to corrosion. Unlike metal grating, which can rust over time when exposed to water, chemicals, or salt air, FRP walkways maintain their structural integrity even in harsh environments such as chemical plants, wastewater treatment facilities, offshore oil platforms, and coastal installations. This makes them especially suitable for applications where traditional materials fail or require frequent maintenance.

FRP walkways are also non-conductive, making them safe for use around electrical equipment and in areas where electrical insulation is important. Additionally, they offer excellent slip resistance thanks to molded-in grit surfaces or textured top layers, which help reduce accidents in wet or oily conditions.

Another major advantage is their lightweight nature. FRP is significantly lighter than steel, making the walkways easier to transport, handle, and install—especially in hard-to-reach or elevated areas. Despite their low weight, they provide high strength and load-bearing capabilities, suitable for both pedestrian and light equipment traffic.

FRP walkways are available in various panel sizes, grating styles (such as square mesh or I-bar), and color options for visibility and customization. Many systems include prefabricated modular components like handrails, stairs, and kick plates to meet safety and regulatory standards.

With minimal maintenance needs and a lifespan often exceeding 20–30 years, FRP walkways offer a cost-effective solution for long-term infrastructure performance in demanding environments. Their combination of safety, durability, and efficiency makes them a smart choice for modern industrial design.

FRP Walkways Specifications & Technical Parameters
