H-beam girders – arches

Designed for extreme loads and maximum stability
Montesino H-beam steel arches are designed for demanding underground applications, offering exceptional load-bearing capacity and structural resilience. Manufactured from high-strength H-sections, they are curved to the specified project radius and finished with welded end plates for secure bolted connections.

Engineered for critical infrastructure
These arches are used in deep tunnels, mines, power plants, and other high-risk geotechnical environments where failure is not an option. Available in various sizes and configurations, they can be delivered as individual segments or pre-assembled arches.
