The Original. Mascot Engineering is one of Australia’s original manufacturers of iron trench grating, with a history dating back to 1920. Our first iron foundry opened near Sydney Airport, and many of our original drainage grates are still in service across Sydney’s streets today. More than 100 years later, Mascot trench grates are trusted on infrastructure projects around the world, delivering durability, safety, and performance.

We manufacture and stock a wide range of trench drainage grating for managing stormwater and surface runoff. Our grates are engineered and tested to meet EN 1433 and EN 124-2 load ratings from Class C250 to Class F900, making them suitable for everything from pedestrian areas to heavy-duty industrial and transport applications such as Airports and Ports.
