Schilcher Trading & Engineering GmbH

Schilcher Trading & Engineering GmbH is an Austrian engineering and trading company that develops and markets the patented X-fix system, a family of metal-free, self-tensioning connectors for cross-laminated timber (CLT) and other engineered wood elements. The company operates the brand X-fix wood connector GmbH and sells its products directly and through a network of CLT producers, timber construction firms, and distributors. X-fix connectors are designed to join CLT wall and floor panels quickly and robustly without additional tools, using a simple wood-to-wood connection. The system is used in wall systems, floor systems (including timber-concrete composites, ribbed and hollow-box floors), modular construction, interior fit-out, and furniture making. Products include the X-fix C connector, X-fix Mini, X-fix RSD tension dowel, and tongue-and-groove connectors. The company is based in Austria and serves markets across Europe, with reference projects in Germany, Austria, the Netherlands, and elsewhere. Its connectors are engineered for load capacities of 14–42 kN in tension and shear, and are promoted for their speed, cost-efficiency, and reversibility. The company collaborates with partners such as HASSLACHER NORICA TIMBER, Züblin Timber AG, Balteschwiler AG, and others to bring X-fix to construction projects.
