Handmade Ductile Iron Manhole Cover
Hand-cast ductile iron manhole cover and frame in round, square, and oval profiles, available across load classes B125–F900 per BS EN124-2:2015. Hand moulding gives flexibility on non-standard sizes, tread patterns, and cast markings at lower tooling cost, while the machined seating stays anti-noise and anti-rock — with an anti-theft, self-sealing hinge.
