Fabricated from hot-dip galvanised mild steel, the grates offer excellent corrosion resistance and are available in various load classes (B, C, or D) to suit foot traffic, light vehicle, or heavy-duty use. These hinged sump grates are built to comply with AS 3996, making them suitable for councils, developers, and contractors across Australia.
