    Steel Has Met Its Match

    At a fraction of the weight of typical steel manholes, FLEX-ING™ brand Composite Manholes give you all the benefits of a solid, well-constructed manhole with none of the difficulties you’ve come to expect from steel. A single technician can easily remove the lightweight cover while the composite construction and design allow the cover to stand up to the harshest forecourt conditions.


     

    Solid Construction, No Compromise

    We don’t compromise with cheap wood or foam fillers. FLEX-ING™ brand Composite Manholes are constructed of many layers of high quality fiberglass bonded together with premium resin and then hand-finished with the utmost attention to quality. The end result is a durable, lightweight cover that not only meets, but exceeds, most testing standards.


     

    Greater Wall Thickness

    FLEX-ING™ brand Composite Manholes feature a domed shape. At their center, our manholes tapper up from 1” to 1 ¼” in wall thickness while most competitive models remain at a uniform 1” wall thickness. This extra wall thickness provides minimal deflection and an extended service life.


     

    Quality Contstruction

    A shallow handle hole and chest-style handle with backer plate keep the wall thickness higher around this high-impact area of the cover. 38" and 42" come standard with spring loaded handle and are available with Cam lock for rain tight applications. Additionally FLEX-ING™ brand Composite Manholes feature a 12 gauge skirt construction that is also powder coated for extreme protection.
