The workhorse of Australian stormwater drainage, the Traditional Stormwater Pit Grate delivers hot-dip galvanised durability across seven sizes and three load classes. The traditional pattern (parallel open-bar design) is engineered for high water flow through standard stormwater pits, making it the builder's default for residential, commercial, and light industrial drainage. Every grate and frame is hinged and lockable, ready to be cast into concrete, with larger sizes double-hinged so one person can open each panel. Since 1957, Vincent Buda and Company has supplied these grates to builders across Sydney and NSW.

Available in Class A (light duty pedestrian), Class B (medium duty residential vehicle), and Class C (heavy duty commercial), all tested to AS 3996:2019. Sizes run from 300mm x 300mm up to 1200mm x 1200mm depending on load class. Vincent Buda and Company stocks the full range for same-day or next-day delivery within the Sydney Metro. Courier delivery available Australia-wide.
