Concrete Bridge Columns

The size and amount of column bars in most columns used in bridge construction make them a good candidate for the use of column ties of Welded Wire Reinforcement. High strength WWR saves steel compared to rebar, saves placing time with sheets of WWR compared to handling and tying individual rebar and improves placing accuracy by using sheets of machine welded and precision bent WWR.

The manufacturing process used by Ivy Steel & Wire gives us the ability to space wires just where they are needed instead of at a fixed 4 inch or 6 inch dimension. The column cage assembly can be composed of several sheets of WWR, bent to exact dimensions that can nest together providing the required lateral support for the vertical column bars. Vertical rebar are simply slipped into the cage and tied at the proper location to complete the cage assembly.

Time and money is saved in preparing the column cage as well as making them adhere to tight tolerances with greater ease. The in-place cost of Welded Wire Reinforcement column ties are less expensive than the rebars they replace and the saving in time of placement can be significant in most jobs.
