Metaklett (from German Metall, metal + Klettband, Velcro ribbon) is a fastening material made of steel that acts on a similar principle to Velcro. It was developed by REINZ-Dichtungs-GmbH, TECHNISCHE UNIVERSITÄT MÜNCHEN, HÖLZEL Stanz- und Feinwerktechnik GmbH & Co. KG and Koenig Verbindungstechnik GmbH. Metaklett is claimed to support shear strength 35 t/m² at temperatures up to 800 °C . It consists of two complementary stripes of 0.2 mm thick perforated steel with catcher and holes. A second variant consists of two stripes with protruding brushes and hooks. There is also a hybrid variant with one metal and one synthetic fleece ribbon.
In the context of the development Dr. Christoph Karl Hein compiled his dissertation "Systematic analysis to metallic hook-and-loop bondings".
