ZeAllgrate Covered fiberglass grating is designed for loading and storage areas with high foot and cart traffic. The fiberglass covered grating panel has one solid fiberglass plate attached to the top surface, which offers strong, level surface and higher stiffness values than that of open mesh gratings. Covered gratings come in two categories: covered molded fiberglass grating and covered pultruded fiberglass grating.

  • Covered molded fiberglass grating
       It is a one-piece molded grating with fiberglass gritted plate cover secondarily fastened to a molded grating panel. It offers solid flooring to prevent contamination of work surfaces below, to control subsurface odors or to prevent tripping hazards for narrow heels.

  • Covered pultruded fiberglass grating
       Covered pultruded fiberglass grating has a top surface available in smooth or gritted top. It is ideal for turning wheel traffic areas or conditions when necessary to eliminate passage of air or debris.
