Embedded Anchor Channel System
Embedded Anchor Channel System
The Embedded Anchor Channel System is a cast-in fixing solution designed for securely attaching mechanical, electrical, and structural components to reinforced concrete structures. It consists of a hot-rolled steel channel with multiple welded anchors on the back, pre-installed during concrete casting.
Compatible T-head bolts can be inserted anywhere along the channel after installation, allowing fast, flexible, and adjustable connections without drilling or damaging the concrete structure.
Compared with traditional post-installed anchors, embedded anchor channels provide higher safety, easier installation, superior corrosion resistance, and excellent dynamic load performance.
History & Development
Embedded anchor channel technology originated in Germany more than 100 years ago.
The system was first widely used in metro tunnel construction in Germany and France during the 1960s. Today, it has become an internationally recognized fastening solution and has been extensively adopted in:
- China
- Japan
- Singapore
- South Korea
- Malaysia
- Hong Kong SAR
- Egypt
