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.

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.

• The DuuMuut Cast Iron Drain Grate is a heavy-duty and durable outdoor drain cover, perfect for concrete floors. Made from sturdy Ductile Iron, it is stronger than cast iron and offers similar performance to steel. This drain grate is built to last for years, with no worries about rusting or deterioration.
• Featuring high-quality materials and fine grinding with anti-rust treatment, this storm drain grate ensures long-lasting durability. Its reinforced back provides increased carrying capacity, making it suitable for heavy loads without damage. You can have peace of mind knowing that this driveway drain cover can handle the pressure.
• The dense hollow design of this trench drainage grate allows for quick and efficient drainage without the risk of clogging. It effectively blocks leaves and debris, protecting your drainage system from blockages.
• Versatility is another great feature of this large drain grate. It is easy to install and can be used in various scenarios, such as parking lots, yards, gardens, channels, garages, and landscaped areas. It is an essential component for an effective drainage system.
• One of the advantages of Ductile Iron is its ability to form an oxidation layer when exposed to the outdoors. This layer acts as a protective barrier, preventing further rusting. Once the oxidation layer is formed, it will not penetrate the interior of the iron, ensuring long-term reliability and performance.
• Invest in the DuuMuut Cast Iron Drain Grate to ensure efficient, reliable, and long-lasting drainage. Your drainage system will thank you for it!

Cast iron drain grate installation method:

1, According to the design of the rainwater mouth size, choose the appropriate drain grate.

2, According to the thickness of the rainwater grate and rainwater grate top surface, determine the rainwater mouth masonry brick top surface elevation.

3, Check the rainwater mouth top surface elevation no problem, sprinkle water on the bottom surface wet, with cement mortar in the need to install the drain grate position sitting 0.8 inches thick mortar, and then place the grate base, base inside edge to use mortar wipe. Installation must keep the base flat, grate base as a whole on the ground, solid and no loose.

4, Install the drain grate, and around the grate base with cement mortar pouring.

5, In order to maintain the appearance of the drain grate beautiful, clear lettering pattern, pay attention to protect the surface of the drain grate when pouring cement, so as not to stain, can not be cleaned.

6, Timely open the grate for cleaning to avoid mortar pouring the water grate and well seat into one, so as not to affect the future opening.
