GRANDO proposes a large range of accredited products for the rail sector, that comply with railway industry norms, such as NF F16-101 and EN 45545-2. With more than 20 years’ experience in the rail sector, our specialist materials science engineers develop low-smoke toxicity self-extinguishing materials (halogen-free) specifically for rail applications and, also more generally, for the transport industry. Thanks to its experience and its reputation, GRANDO has become a major supplier of accredited normative materials for the rail industry.

Our main objective : passenger safety

To improve passenger safety, train operators and builders are imposing ever stricter fire/smoke standards. In response to this demand, GRANDO has for several years been developing and manufacturing materials that meet the new technical requirements in collaboration with several R&D laboratories and other industrial partners.

Over the years, GRANDO has managed to develop an increasingly complete range of products that comply with railway norms in terms of category of product and fire/smoke classification, while significantly improving their self-extinguishing performance as well as eliminating halogen emissions. Aware that current national European standards will eventually be replaced by a single European standard, EN 45-545, GRANDO already offers its customers a varied range of products classified according to this standard, making it an undisputed leader on this niche market.

All our materials are accredited in accordance with at least one of the following international fire/smoke norms that apply to the railway sector:

European fire-smoke standards :

  • NF F16-101/NF F16-102 (French standard)
  • DIN 5510 (German standard)
  • BS 6853 (British standard)
  • UNI (EN ISO 11925-2:2002) (Italian standard)
  • EN 45-545 (European standard)

North American fire-smoke standard :

  • ASTM C1166, E162, E662
  • UL 94

Russian fire-smoke standard:

  • GOST

These materials can also be developed specifically according to customers’ technical and normative criteria.
