Once welded or bolted in place, Contech Bridge Plank restores strength to old structures and stiffens bridges laterally, providing a solid base for new asphalt paving and eliminating rattles.

With Contech Steel Bridge Plank, there is nothing to crack, warp or rot. Repeated, expensive repair work on the bridge floor comes to a halt, and the danger of fire is minimized. Our Bridge Plank also eliminates reduced load limits caused by inadequate flooring.

Contech Steel Bridge Plank comes in different corrugation patterns to fit various deck loading requirements. Installation requires no special crews or equipment. The structural-quality steel used to manufacture our Bridge Plank conforms to the requirements of ASTM A 1011, ASTM A 929, ASTM A 653 or ASTM A 1018, depending on the steel thickness. Zinc coatings, when ordered, are in accordance with ASTM A 123 (for hot-dip galvanized) or ASTM A 929 (for Pre-galvanized or Aluminized Type 2).

Benefits of Bridge Plank:

  • Rigid panel construction - Restores strength to old structures. Positive welded connections help stiffen the entire structure and the deck becomes an integral part of the bridge
  • Galvanized steel planks - Long service life with minimal maintenance 
  • High strength-to-weight ratio - Total weight is only slightly higher than most timber floors and in some cases (especially replacement of reinforced concrete decks) the load is actually reduced
  • Convenient lengths and standard sizes with no special equipment or training - Fast, low-cost installation
