The Role of Steel Gratings in Highway Tunnels

Steel gratings are key components of highway tunnel drainage systems. Their permeable structure allows for the efficient diversion of surface water, preventing accumulation that could compromise driving safety.

During tunnel maintenance operations, steel gratings can be used to construct temporary safety walkways, providing a stable working platform for personnel without hindering the tunnels drainage functions.

Furthermore, steel gratings are used to protect tunnel ventilation openings. By ensuring proper airflow while preventing debris from entering the ventilation system, they enhance the overall operational stability of the tunnel.
