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. Up to 3 steel plates, each up to 5 mm thick, can be penetrated. 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
