Doors in underground stations not only have to meet fire protection, security and safety requirements, but in particular they have to be able to handle pressure. This was also one of the key requirements for the doors of the new Crossrail stations in London. Here, security doors were required that had to be fire, sound and pressure resistant. Teckentrup was able to offer appropriate door solutions with corresponding conformity, which also complied with the revised, stricter version of LPS 1175 for proof of product certification. In addition, all required values for soft impact tests, structural strength data, „U“ values, cycle tests and life cycles could be met.
