Frequently Asked Questions
D400 is a load class that indicates the cover can withstand a test load of 400kN, making it suitable for carriageways of roads, hard shoulders, and parking areas used by all types of road vehicles.
Bitumen painting provides a thick, waterproof, and chemical-resistant barrier that is specifically designed for underground and road environments to prevent rust and corrosion.
Unlike grey iron, ductile iron contains spherical graphite nodules, which give it much higher tensile strength and flexibility, preventing the product from cracking under sudden impact.
Yes, while JRC12 is a standard model, we can provide various specifications and sizes based on your project requirements in the metal products manufacturing sector.
Absolutely. Its high durability and protective coating make it an excellent choice for telecom manhole covers that require long-term stability and protection for underground cabling.
Due to the nature of bitumen, very little maintenance is required. Periodic inspection for physical damage to the coating is recommended to ensure the metal remains protected.
