Cast Iron Trench Drain Grate 20x12 Inch, C-Class Heavy Duty Black Rectangular Sewer Cover

Cast iron is the material specification for drain grates that need to handle serious load — not just foot traffic, but vehicle axle loads, delivery trucks, and the repeated impact of daily commercial use. C-class load rating means this grate is tested and rated for the loads encountered on roads and commercial driveways, not just residential footpaths.

The 20x12-inch rectangular format covers a standard trench channel opening in a single piece. The black finish is inherent to the cast iron material — not a coating that chips or fades, but the natural colour of the metal that stays consistent for the life of the installation.

• C-class load rating — tested and rated for vehicle axle loads on roads and commercial driveways; the load class that goes beyond residential foot traffic.
• Cast iron construction — the material specification for permanent heavy-duty outdoor drain covers; inherently black, inherently durable, no coating to chip or fade.
• 20x12 inch rectangular format — covers a standard trench channel opening in a single piece; no joints, no gaps, no debris ingress between sections.
• Heavy duty outdoor application — suitable for driveways, roads, commercial yards, parking areas, and any outdoor channel where vehicle load is expected.

The grate that handles the load that lighter materials can't. Cast iron, C-class rated, built for the long term.
