About PASS+CO
PASS+CO INTERNATIONAL GmbH is a family-owned company based in Wilnsdorf near Siegen and is regarded as the oldest German manufacturer of steel safety barrier systems. The product range covers vehicle restraint systems (VRS) to EN 1317 in all containment levels: single-sided and double-sided safety barriers, bridge parapets, end terminals, crash cushions, motorcycle protection systems as well as clad and wooden safety barriers. Production includes the rolling of A-profiles (2.5 mm in S355, 3.0 mm in S235) on an in-house profiling machine, hot-dip galvanizing to EN 1461:2009 in an own plant, and installation with in-house installation teams. Since 1968, the company has also processed heat-resistant stainless steels to customer drawings for vessel and apparatus construction. The group is represented with sales and installation companies in numerous European countries as well as in Turkey, India and Algeria, and does business in 110 countries worldwide.
