About verttec Industrieklettern
verttec Industrieklettern from Bochum has been carrying out rope-assisted work at height in North Rhine-Westphalia and nationwide since 2007. The team of professional industrial climbers, who are also qualified skilled tradespeople (including electricians, mechatronics technicians and concrete restorers), reaches high, deep or hard-to-access workplaces using rope access and positioning techniques (SZT/SZP) – without scaffolding or aerial work platforms. The service portfolio covers mobile communications (new builds, conversions, maintenance, fault clearance, antenna installation, 5G expansion), structural steel assembly and component replacement on running installations, corrosion protection, facade cleaning using a chemical-free hot-water high-pressure process, concrete restoration, planning and installation of fall protection systems, installation of fire alarm systems and smoke suction systems, photovoltaic installation, and commercial high-angle and confined-space rescue (SRHT). Working materials are steel, concrete, aluminium, glass, sandwich panels and trapezoidal sheet metal. Clients include general contractors, industrial developers, plant managers and technical buyers, including BioNTech, Deutsche Telekom and various mobile network operators with 400–700 maintained sites annually.
