You can assemble high-quality steeltimber joints using the HECO®-WS system. The dowels are inserted in the timber and through the steel plates in a single, time-saving operation without pilot drilling. 3 steel plates up to 5 mm thick or 1 steel plate with up to 10 mm thick can be penetrated (steel grade: S235). Producing joints for framework structures has been a complicated process to date. The new HECO®-WS system reduces the procedure to a few operating steps: 1. fitting the steel plate 2. aligning and fixing it in position 3. inserting the dowel
