【High-quality Materials】This cast iron drain grate is made of ductile iron. It is not easy to age, rust and corrode. Even if it is in a humid environment for a long time, it can maintain the good performance of the material. And it has better tensile resistance and is suitable for long-term use. 【Strong Bearing Capacity】This cast iron drain grate adopts a heavy-duty structure with good pressure resistance and can reach up to 661.39LBS. Installed on the road, it is strong enough to bear greater pressure without being easily damaged. 【Anti-slip Design】The rough anti-slip surface and many holes of this heavy-duty cast iron drainage grate increase the friction to prevent pedestrians from falling. 【Grille Drainage】It is designed with many gridded drainage openings, which can drain sewage more quickly. The grille opening is properly sized and can also effectively filter out larger debris such as dead leaves and plastic bags to prevent clogging of the drain. 【Simple Installation】This cast iron drain grate is an integrated structure, which can be installed directly when receiving the goods. The middle hollow design is also very convenient for you to grab with your hands to install.
