Frequently Asked Questions
Ductile iron possesses much higher tensile strength and flexibility, meaning it can bend under pressure without cracking, unlike brittle grey iron.
C250 refers to the load class rating, indicating the cover is designed to withstand specific test loads typical for residential and light commercial areas.
Bitumen coating acts as a waterproof and anti-corrosive shield, preventing moisture and salts from reacting with the iron surface.
Yes, the L6T design is compatible with various utility needs, including drainage and telecom access, provided the load class meets site requirements.
The C250 rating is ideal for parking lots and light traffic areas. For heavy highway traffic, we recommend checking our higher load-rated products.
The bitumen finish is designed for low maintenance; however, ensuring the edges are clear of debris helps maintain the seal and coating integrity.
