The Composite Manhole is manufactured with a lightweight composite cover, which is stronger than steel at less than 25% of the weight. The composite cover is constructed of environmentally safe materials, which are not permeable or weakened if exposed to hydro carbons. The composite materials are non-conductive to electrical currents and do not develop and/or hold electrical charges. The manhole also features a 1 1/2" wide steel ring frame, an easy grip recessed handle on the cover, 14 gauge galvanized steel skirt. Available in a variety of sizes.
