[Nylon Coating Example] Manhole for Use in Highway Tunnels
Introducing examples of manholes installed in pedestrian emergency lanes on highways!
We would like to introduce a case where our nylon coating technology was adopted for manholes used in highway tunnels. There was consideration to use only galvanized corrugated steel plates as manhole covers, but there was a possibility of corrosion due to the humidity inside the tunnel and the influence of de-icing agents during winter. Therefore, to provide stronger corrosion resistance, nylon coating was applied over the zinc plating. 【Case Overview】 ■Part Name: Manhole for Highway Tunnel ■Issue: Corrosion due to humidity inside the tunnel and the influence of de-icing agents during winter ■Construction Details: Nylon coating applied over zinc plating ■Effect: Allows for double corrosion protection by covering the plating layer *For more details, please download the PDF or feel free to contact us.
