Manufacturing process of a cast iron pipe

Why use cast iron

Pioneer in fire protection & sustainable construction

Proven for centuries, cast iron has been the most durable material that drainage technology relies on. Read more about the positive properties of cast iron drainage pipes here.

Cast iron is a particularly durable material and has been installed in numerous buildings, infrastructures and industrial applications: reliable, stable and resistant.

Due to the sustainability of the material, cast-iron drainage technology is an important criterion for obtaining national or international building certifications.

  • Cast iron does not burn
  • Excellent sound insulation properties
  • Ideal eco-balance with 100 % recycling
  • Durable and reliable

Cast iron does not burn

Cast iron pipes offer long-lasting safety when it comes to fire protection: the reason is obvious, because unlike plastic, cast iron simply does not burn. We have also proven this in our IZEG fire test.

Cast iron is a sustainable recyclable material

Environmentally friendly and with a first-class eco-balance: cast iron drainage pipes consist to almost 100 percent of recycled pipes and scrap iron. In the case of used pipes, 100 percent of the cast iron material can in turn be returned to the recyclable material cycle for iron products.

Cast iron is quiet

Due to its high wall weight, cast iron naturally dampens structure-borne sound. In terms of airborne sound, cast-iron drainage systems are also more quiet - in contrast to plastic. Wastewater noises are simply less audible, which significantly increases living comfort.

Building certifications

Cast iron drainage systems are an important milestone for obtaining recognised sustainable building certifications - such as DGNB, BNB, LEED or BREEAM: With the particularly sustainable material cast iron, you can easily meet all the requirements of the certifying organisations to construct sustainable buildings.
