Staco - Model Type RH -Pressed Gratings
Heavy duty gratings are made of thicker steel of 4 or 5 mm and have standard flat edging, with the edge thickness being the same as the bearing bars. The use of thicker steel greatly increases the load carrying capacity which makes these gratings ideally suited for extra heavy loads. Heavy duty gratings are widely used in industrial and residential building. Anti-slip serration is possible on both the bearing and crossbars of all types.
