Ductile Iron Grates and Frames
Our Ductile Iron Grates and Frames offer a high-strength, long-lasting solution for stormwater drainage in roads, car parks, industrial zones, and public infrastructure projects.
Designed for heavy-duty performance, ductile iron delivers superior tensile strength, impact resistance, and durability compared to traditional cast iron.
Available in a wide range of sizes and load classes, these grates are ideal for high-traffic areas requiring compliance with AS 3996. The frames are precision-cast for secure seating, while the grates are engineered to handle vehicular, pedestrian, or industrial equipment traffic.
