Founded in 2014 - Experience since 1988

Company owner Robert Ploke has been active in this field since 1988. He has supervised countless bolting projects on site throughout Europe in many areas of heavy industry. Due to his many years as co-owner and managing director at the former company P&S Vorspannsysteme AG in St. Gallenkappel, whose co-founders were Rolf Steinbock and his father Gerhard Ploke, he is very familiar with large bolted joints and their special requirements (see also History).
