Our ironwork designs employ cover or grating elements that are intended for; Lifting out from the frame and/or hinging within the frame, where the latter may include one of up to three hinged-opening directions.
Some hinged-opening designs allow the cover or grating element hinges to be repositioned [prior to installation] in order to change the hinged-opening direction
Non-hinged, Double-Triangular cover and grating elements, <1m Clear Opening, employ loose-link fasteners between two adjoining cover elements which require those cover segments to be lifted out from the frame, as a pair.
Non-hinged, Double-Triangular cover and grating elements, >1m Clear Opening, do not employ loose-link fasteners between the cover elements and therefore require lifting out from the frame as individual cover segments
Hinged, Double-Triangular cover elements which also include a cover lift-out option (i.e. Highway Halo), do not employ loose-link fasteners between the cover elements. These therefore can be lifted out from the frame individually.
