Cast Iron Trench Drain Grate 20x10 Inch, Heavy Duty Outdoor Channel Drainage Cover

Cast iron drain grates earn their specification in applications where load, longevity, and chemical resistance all matter simultaneously. The 20x10-inch format covers a standard trench channel opening in a single piece — no joints, no gaps, no debris ingress between sections — and the cast iron construction handles vehicle axle loads, freeze-thaw cycling, and chemical exposure without deforming or degrading.

The inherent black colour of cast iron is not a coating — it's the material itself. There's nothing to chip, nothing to fade, and nothing to maintain. The grate looks the same in year ten as it did on installation day.

• Cast iron construction — handles vehicle axle loads, freeze-thaw cycling, and chemical exposure; the material that outlasts coated steel and plastic alternatives in permanent outdoor applications.
• 20x10 inch single-piece format — covers a standard trench channel opening without joints or gaps; no debris ingress between sections.
• Inherent black finish — the natural colour of cast iron, not a coating; nothing to chip, nothing to fade, nothing to maintain.
• Heavy duty outdoor application — suitable for driveways, roads, commercial yards, parking areas, and any outdoor channel where vehicle load is expected.

The drain grate that needs no maintenance and makes no compromises. Cast iron, heavy duty, built for the long term.
