Build a sustainable future with cast iron!

Future-oriented infrastructure design focuses on structures’ entire life cycle, both in terms of cost to future customers and the long-term impact on environment and society.

With their outstanding material properties, cast iron pipes according to EN 877 from PREIS® DS make for robust, durable drainage system for road, bridge and tunnel drainage.

Dimensionally stable and capable of withstanding shocks and high temperature fluctuations, the PREIS® BML pipe system is superior to other products in infrastructure projects and has a positive impact on the entire life cycle of the construction as a whole.

FAQ

The sustainability is based on the material cast iron:

  • Environmentally friendly – up to 100% recyclable
  • Resource saving – pipes are made of up to 100% scrap iron
  • Durable – a lifespan of 50 years and more
  • Sustainable – valuable recycling raw material instead of disposal costs
  • Sustainable – valuable recycling raw material instead of disposal costs
  • Safety – non-flammable (highest fire protection class A1 or A2)
  • Low noise emission – effective soundproofing by design
