Cascada's MRWA grate is made to the specifications of Main Roads WA.

Designed to last on WA's most demanding roads, these grates have a large opening to accommodate for high water flows and heavy bars to withstand the impact of thousands of trucks and cars per day.

Cascada supplies these covers ready for you to install on site, or we can encase them in concrete to the range of configurations that meet Main Roads WA specifications including the GT, GN and HN grated covers.
