Fiberglass-reinforced plastic (FRP) corrosion-resistant grating, stair treads and railings from Fibergrate Composite Structures are used to build platforms that provide safe access to restroom trailers. The components are manufactured with specially formulated resin systems that will not rust or rot, reducing overall maintenance. The slip-resistant surfaces provide added safety, and the lightweight composite will reduce the overall weight of trailer systems. 800/527-4043; www.fibergrate.com.
