Generally, epoxy-coated rebar have performed well in resisting corrosion in deicing-salt environments. But there have been isolated incidents, primarily in structures located in sea water environments, of unsatisfactory performance. Recent research shows epoxy-coated rebar performance is related to coating quality. The more holidays (pinholes not visible to the naked eye) and damage the coating has, the less effective it is in protecting against corrosion. Most damage to epoxy-coated bar occurs during shipment to and handling at the jobsite. The following storage practices can help prevent coating damage: * Store bars above ground on timbers or other protective cribbing. Space the supports close enough to prevent sags in the bundles. * If storing many bars in a small area, stack bundles of straight bars with adequate blocking placed between bundle layers. Stacking may not be practical for bent bars. * Cover bars or bundles with opaque polyethylene sheeting or other suitable protective material. For stacked bundles, drape the protective covering over the sides of the bundles and around the perimeter of the stack. Secure the covering adequately, and allow for air circulation around the bars to prevent condensation under the covering. * To ensure accurate identification of the stored bars, protect the nonmetallic marking tags on the bundles or attach backup galvanized metal tags to the bundles.
