## Features

- HEAVY DUTY & STURDY: This metal drain grate is made from durable Ductile Iron, which is stronger than cast iron and has similar performance to steel. This outdoor drain grate will last for years without deteriorating
- MORE CARRYING CAPACITY: The back of drainage grates outdoor is strengthening. So it is strong enough to withstand more pressure and won't easily damage. This will keep you more secure when using this driveway drain cover
- MULTIPLE USAGE SCENARIOS: An effective drainage system starts at the top. The large drain grate is easy to install. The garage drain cover can drain away heavy flows of surface water from parking lots, yard, garden, channel, garage and landscaped areas
- RUST-RESISTANT DUCTILE IRON: Unlike regular iron, ductile iron placed outdoors undergoes a normal oxidation process. Once the oxidation layer forms on the surface, it acts as a protective barrier and prevents further rusting. This means that the ductile iron drain grate will not rust like regular iron, ensuring its longevity and performance. Say goodbye to layers of peeling rust with this rust-resistant ductile iron drain grate
- Metal drainage grate boasts excellent weather resistance. It won’t fade or age even when exposed to direct sunlight or humid environments for a long time. With a service life far exceeding plastic products, its robust anti-aging performance ensures worry-free use for years.
- Load Rating B Class: Suitable for Light Vehicle Traffic. Applicable Traffic/Vehicles: Passenger cars, SUVs, light vans, small trucks. Speed Limit: ≤5 km/h (safe for low-speed light-duty vehicle passage)
