The monitoring of door openings and closings not only concerns the building’s access points – very often it is also required to lock other elements such as cupboards, mailboxes, lockers or even machines. All these locking solutions are called industrial applications. Back in 1985, STS pioneered the development of security cylinders for the most demanding requirements, as well as the handling of products by professional security installers. Since a few years ago, STS has become a part of TESA ASSA ABLOY, resulting in the union of two reference manufacturers of security locks in the industrial, institutional and residential segments.
