As a leading manufacturer, we specialize in producing manhole covers that meet global standards, catering to urban infrastructure, industrial projects, and specialized environments like ports and docks.
Our square ductile cast iron manhole covers are crafted using advanced green sand casting technology, ensuring precision and consistency in every piece. Ductile iron, known for its superior strength-to-weight ratio, offers greater durability compared to traditional cast iron, making it ideal for heavy-duty applications. These covers are available in various load ratings, from B125 for light-duty pedestrian areas to F900 for extreme load environments like airports and ports, capable of withstanding up to 90 tons. The square design is particularly suited for urban settings, providing a seamless fit for sidewalks, pedestrian plazas, and other areas where aesthetics and functionality are equally important.
At Jinlong Foundry, we offer a range of square ductile cast iron manhole covers, including the square light duty B125 cast iron manhole cover for residential and pedestrian zones, as well as the square waterproof cast iron manhole cover for areas prone to water ingress. Our products are corrosion-resistant, thanks to specialized coatings, ensuring a lifespan of over 30 years with minimal maintenance. We also provide customization options, allowing you to tailor sizes, load capacities, and even add decorative infills or logos to match your project’s needs, similar to our B125 decorative infilled manhole cover.
