Liner plates, which were developed as a tunnel lining material, are corrugated thin steel sheet with flanges attached on four sides. Because of their outstanding features, our liner plates are used widely in shafts (for deep foundation and jacking methods), catchment wells and other applications.

Liner plate of the present invention has excellent thermotolerance and solidity to corrosion, has higher hardness and wear resistance, also has higher intensity and good toughness simultaneously, and its wear resistance improved more than 2 times than the high manganese steel lining plate life-span, and cost effective.
