Frequently Asked Questions
D400 indicates the cover is designed for areas where heavy traffic is expected, such as main roads, parking lots, and industrial yards, capable of withstanding a test load of 400kN.
Bitumen painting provides a waterproof and anti-corrosive layer that prevents the ductile iron from rusting when exposed to moisture and soil chemicals.
Ductile iron contains spherical graphite, which allows it to bend without breaking, providing much higher tensile strength and durability than the brittle structure of grey iron.
Yes, while designed for heavy loads, its structural integrity and corrosion resistance make it an excellent choice for protecting telecom and utility infrastructure.
Depending on the environmental conditions and traffic volume, these covers are typically designed to last over 10-15 years with minimal maintenance.
Our manufacturing process allows for customization based on engineering drawings to ensure a perfect fit for specific municipal or industrial requirements.
