Frequently Asked Questions
D400 refers to the load class capable of withstanding a test load of 400kN. This makes the LWRC1004-3 suitable for areas with heavy traffic, such as main roads, parking lots, and industrial zones.
Black bitumen painting creates a waterproof and chemical-resistant layer on the metal surface, preventing rust and corrosion caused by soil moisture and road salts.
Ductile iron contains spherical graphite, which provides significantly higher tensile strength and impact resistance, meaning it bends rather than snaps under extreme pressure.
Yes, while this model is optimized for heavy load, the material quality and protective coating make it highly suitable for telecom and electrical utility access points.
Absolutely. Ductile iron retains its structural properties across a wide range of temperatures, ensuring it won't crack during winter freezes or warp during summer heat.
We recommend matching the cover with our corresponding steel frame manhole covers to ensure a precision fit and maximize the load-bearing efficiency of the D400 rating.
