    The surface is integrated during the manufacturing process with open texture to resist dirt build-up and ensure non-slip resistance throughout working life.

    Composite lids will not corrode when in contact with other materials. Unaffected by sand, salt and all chemicals met in road environments.

    A lightweight lid with one-man lifting mechanism allows single person maintenance and cleaning, saving dollars and injuries. The lift and drag method of removing lids is backed by university research as the safest way to open lids.


    Our fantastic new pricing makes our covers directly competitive with concrete and steel covers and incredibly cheap when you factor in maintenance and whole-of-life savings.
