Metaklett: The High-Strength Steel Hook-and-Loop Fastener
Imagine a fastening system with the convenience of Velcro but the raw power of industrial steel. This is the essence of Metaklett, a specialized fastening material designed to provide secure, reusable bonds in environments where traditional synthetic fasteners would fail. Derived from the German words Metall (metal) and Klettband (Velcro ribbon), Metaklett adapts the familiar hook-and-loop principle for heavy-duty engineering applications.
Development and Engineering
Metaklett is the result of a collaborative effort between academic research and industrial expertise. The material was developed through a partnership involving the Technical University of Munich, Reinz-Dichtungs-GmbH, Hölzel Stanz- und Feinwerktechnik GmbH & Co. KG, and Koenig Verbindungstechnik GmbH. The theoretical foundation for this technology was further detailed in the dissertation by Dr. Christoph Karl Hein, titled "Systematic analysis to metallic hook-and-loop bondings."
[ไม่มีภาพประกอบ]Technical Specifications and Performance
Unlike plastic fasteners, Metaklett is engineered to withstand extreme mechanical stress and thermal conditions. It is capable of supporting a shear strength—the ability to resist forces that cause the fastened layers to slide against each other—of 35 tonnes per square meter. Furthermore, it maintains its structural integrity at temperatures reaching up to 800 °C.
Material Variants
To suit different industrial needs, Metaklett is available in three primary configurations:
- Perforated Steel: This version consists of two complementary strips of 0.2 mm thick perforated steel, utilizing a system of catchers and holes to create a bond.
- Brush and Hook: A variant featuring two strips equipped with protruding brushes and hooks for engagement.
- Hybrid: A combination system utilizing one metal strip and one synthetic fleece ribbon.
Key Facts
- Maximum Temperature: Stable up to 800 °C.
- Shear Strength: 35 tonnes per square meter.
- Material Thickness: 0.2 mm for perforated steel versions.
- Origin: Developed by a consortium of German companies and the Technical University of Munich.
- Mechanism: Based on the hook-and-loop principle.

Frequently Asked Questions
What is Metaklett?
Metaklett is a metal-based fastening material made of steel that operates on the same principle as conventional hook-and-loop fasteners (Velcro), but is designed for high-strength and high-temperature industrial use.
How much weight can Metaklett support?
It is claimed to support a shear strength of 35 tonnes per square meter.
Can Metaklett be used in high-heat environments?
Yes, Metaklett is designed to remain functional at temperatures up to 800 °C.
What are the different types of Metaklett available?
There are three versions: a perforated steel variant (catchers and holes), a brush-and-hook variant, and a hybrid variant that combines metal with synthetic fleece.
Who developed this technology?
It was developed by the Technical University of Munich in collaboration with Reinz-Dichtungs-GmbH, Hölzel Stanz- und Feinwerktechnik GmbH & Co. KG, and Koenig Verbindungstechnik GmbH.
