HEAVY DUTY & STURDY: Made from durable Ductile Iron, this metal drain grate is stronger than cast iron and has similar performance to steel. The outdoor drain grate will last for years without deteriorating, providing long-lasting durability for your drainage system MORE CARRYING CAPACITY: The back of this outdoor drain grate is strengthened to provide additional support and carrying capacity. This ensures that the drain grate is strong enough to withstand more pressure and won't easily damage or bend. With its increased carrying capacity, you can trust this driveway drain cover to effectively manage heavy flows of surface water MULTIPLE USAGE SCENARIOS: This large drain grate is versatile and can be used in various scenarios. It is easy to install, making it suitable for installation in parking lots, yards, gardens, channels, garages, and landscaped areas. With its reliable performance and durability, this drain grate is an effective solution for maintaining a efficient drainage system 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)

Features of ductile iron drain covers:

1.Good toughness - The impact value is similar to that of medium carbon steel, and is more than 10 times that of gray iron material.

2.Strong corrosion - resistance Water spray corrosion test, ninety days of corrosion is only 1/40 of steel pipe, 1/10 of anorexic iron pipe. service life is 2 times of gray iron pipe, 5 times of ordinary steel pipe.

3.Good plasticity - Elongation ≥ 7%, similar to high carbon steel, while the elongation of gray iron material is zero.

4.High strength - Tensile strength ≥ 420MPA, yield strength ≥ 300MPA, the same as low carbon steel, three times the gray iron material.Due to its spherical graphite microstructure, ductile iron is superior to cast steel in terms of its ability to damp vibrations and is therefore more conducive to stress reduction.

Due to its spherical graphite microstructure, ductile iron is superior to cast steel in terms of its ability to damp vibrations and is therefore more conducive to stress reduction.

The strength of ductile iron is comparable to that of cast steel. Ductile iron has a higher yield strength, with a minimum yield strength of 40 K. The yield strength of cast steel is only 36 K.

In most applications, such as water, salt water, steam, etc., ductile iron exceeds cast steel in corrosion and oxidation resistance.
