Girder Bird Spikes are a physical bird deterrent used to prevent pigeons and larger pest birds from landing or nesting on girders or I-beams. Birds cannot land on the un-even surface created by the spikes and will move on to a better spot. Girder Spikes are sold in three widths (3”, 5” & 8”), two foot sections, and 50 feet per box and are available in a variety of widths to cover the surface to be treated.
