Benefits of Cast Iron
Cast iron is particularly well suited for all drainage systems as it offers many benefits, both for
above and below ground installation, which include:
Strength and durability - cast iron pipes are highly resistant to distortion caused by accident
or vandalism.
Long life - when correctly installed cast iron drainage systems will last the life of the building,
whether domestic, public, industrial or commercial.
Low maintenance - cast iron requires little ongoing maintenance, annual inspections are
recommended but remedial action is rarely required.
Design Capability - cast iron can meet the needs of restoration, refurbishment, conservation and
heritage work as well as new, bespoke and unique designs.
Sustainability - in addition to lasting the life of a building and requiring minimal maintenance, cast
iron is also 100% recyclable and can therefore be used again after the building has gone.
Cost effective - owing to its longevity, durability and low maintenance, coupled with its fire
resistance and low noise operation, the cost benefits of cast iron are significant.
Fire resistance and Safety - The melting point of cast iron is considerably higher than PVCu or PE
and in the event of a fire will not emit toxic fumes or drop burning globules of material from one
compartment to another.
