Steel Bridge Decking

Steel Bridge Decking is used in new bridge construction or to rehabilitate existing structures. Steel decked bridges can be built in any weather conditions. AIL roll forms bridge decking at a 25.4 mm (4 ¼") depth using Grade 50 steel in either pre-galvanized or bare steel. If the latter is used, it can be prime painted.

• Available pre-galvanized or bare steel
• Can be built in any weather conditions
• Affordable strengthening solution for existing bridges
• Nests for economical shipping

Bridge Deck Fastening

• Weld each piece to stringer with deck thickness x 3" fillet welds.
• Weld between stringers at overlap with 3" fillet weld every 30"± or between stringers.
• End splices are to be staggered and located over stringers. Crests of end splices are to be butt welded.

Asphalt Surface Installation Instructions

• Clean metal surfaces of all foreign matter.
• Apply tack coat over the deck surface.
• Fill and compact all corrugation troughs with asphalt to the top of the deck.
• Overlay with a leveling course and additional courses as necessary to achieve a final wearing course. Compact to required density.
