Our company selects high-quality ductile iron and high-strength composite materials to create various manhole cover products with exquisite durability and practicality. The ductile iron manhole cover adopts advanced production technology, with a tensile strength of up to 600MPa and a load-bearing capacity that meets C250 to D400 standards. It is suitable for high load scenarios such as urban main roads and highways; Composite manhole covers stand out for their lightweight design and excellent corrosion resistance. They are acid and alkali resistant and anti-aging, especially suitable for chemical parks and coastal high salt fog environments. The product surface has undergone special treatment and has excellent high temperature resistance. It can operate stably under extreme temperature differences of -40 ℃ to+200 ℃ without deformation or fading. The unique anti slip texture design, combined with invisible shock absorption structure, not only ensures the safety of pedestrians and vehicles, but also effectively reduces noise pollution. All manhole covers have passed national quality inspection and certification, supporting customized sizes and labeling, providing comprehensive solutions for municipal engineering, commercial buildings, and industrial parks. Choosing our product means choosing a long-lasting and reliable guarantee.
