Summary
This type of system is optimal when the tunnel wall does not have major irregularities, since the panel is fixed against the wall by means of an omega-shaped sheet. Therefore, its width is practically the same as that of the panel, taking up as little space as possible.

Characteristics
- Metal.
- Adaptable to curved tunnels.
- Lightness.
- High absorption.
