Square Ductile Iron Manhole Cover C250 Load Bearing Grade 800×800mm

Square Ductile Iron Manhole Cover C250 Load-Bearing Grade 800×800mm​

Performance characteristics

High strength: tensile strength ≥420MPa, yield strength ≥300MPa, can withstand large loads (such as D400 grade can withstand about 40 tons of load), not easy to deform and damage, suitable for frequent vehicle traffic scenes.

Good toughness: The impact value is similar to that of medium carbon steel, more than 10 times that of gray iron materials, not easy to break under impact, and has advantages in dealing with road vehicle crushing and accidental collisions.

Strong corrosion resistance: In the water spray corrosion test, the corrosion amount in 90 days is only 1/40 of steel pipes and 1/10 of gray iron pipes. The service life is long, which is 2 times that of gray iron pipes and 5 times that of ordinary steel pipes. It is suitable for humid and acid-base corrosive environments (such as sewage wells).

Anti-theft: often equipped with anti-theft devices (such as bolt fixing, special locks) to prevent theft or illegal opening and ensure the safety of underground facilities.

Aesthetics and adaptability: The square design can be coordinated with the surrounding environment (such as sidewalks, community roads), the surface can be anti-slip treated (square patterns, etc.) to enhance the safety of pedestrians and vehicles, and can also be customized according to the size of the wellhead (such as 500×500mm, 800×800mm, etc.).
