    Take control of stormwater and overland flows. Our extensive range of grates and drains includes various options for external use. Find backyard drainage solutions that work–linear drains in both Heelguard and traditional line patterns for driveway grate drains alongside outdoor slot drains and square floor wastes for larger volumes of water.

    Proudly made in Australia and compliant with all Australian Standards, our outdoor drainage grates feature marine-grade 316 stainless steel or hot dip galvanised steel to ensure durability. Each of our external grate and drains are available with a range of drainage accessories (sold separately), including end caps, outlets and filters to suit your chosen product.
