WORKPIECE SAMPLES

The culvert corrugated plate is corrugated metal sheeting that's used as a structural roof deck or composite floor deck. It will be supported by steel beams or joists The purpose of metal deck is to support the insulating membrane of a roof or to support and bond with the concrete to create a composite metal floor deck.

APPLICATION

The culvert corrugated board production line is a special equipment for culvert corrugated board compression molding, which is widely used in construction industry and other facilities, including railway bridge tunnels, highway bridge tunnels etc.
