Epoxy coated rebar

Epoxy coated rebar

corrosion-resistent epoxy coating

Epoxy-Coating protects the steel using several mechanisms. If undamaged, the coating prohibits the passage of chloride ions, thus protecting the steel from corrosion damage. If minor holes or damage are present in the coating and sufficient chloride ions are available in the concrete, then localized corrosion may occur. For the corrosion reaction to proceed, a cathode is required. If all bars are coated, then only very small cathodes are present, substantially reducing the corrosion rate. Tests conducted for the FHWA demonstrated that if both top and bottom mats were coated, the corrosion rates of Epoxy-Coated Steel Reinforcing Bars were 40 to 50 times less than that of similar uncoated bars.

Epoxy-Coated rebar may be used in any concrete subjected to corrosive conditions. These may include exposure to deicing salts or marine waters.

Manufacturing process

 
Surface preparation
Surface preparation

Rebars are blast-cleaned to a near white metal finish using abrasive grit.

Heating
Heating

Bars are heated to approximately 230°C, typically using electrical induction heaters.

Powder application
Powder application

The heated steel is passed through a powder-spray booth where the dry epoxy powder is emitted from a number of spray guns.
