Epoxy Coating For Steel Reinforcement

131 in piers the use of epoxy coated reinforcing steel should be continued into an area.

Epoxy coating for steel reinforcement.

Epoxy coated steel reinforcing bars rebar may be used in any concrete subjected to corrosive conditions. Using certain types of epoxies yielded positive results especially in steel exposed to seawater while evaluating the use of epoxy to coat steel reinforcements exposed to chloride attack. Reinforcing steel bars meeting astm a775 a775m standard specification for epoxy coated steel reinforcing bars are coated in a straight condition and then bent whereas astm a934 a934m standard specification for epoxy coated prefabricated steel reinforcing bars covers bars that are bent prior to coating. The epoxy is applied to preheated steel as a dry powder which melts and cures to a uniform coating thickness for excellent adhesion on concrete steel bar.

However 129 when using epoxy coated reinforcing steel in decks it is recommended that all the deck 130 steel is coated as this will reduce the overall rate of corrosion if the coating is damaged. Fusion bonded epoxy coating also known as fusion bond epoxy powder coating and commonly referred to as fbe coating is an epoxy based powder coating that is widely used to protect steel pipe used in pipeline construction concrete reinforcing bars and on a wide variety of piping connections valves etc. These may include exposure to deicing salts or marine waters.

Scotchkote 413 is a one part heat curable thermosetting epoxy coating designed for corrosion protection of reinforcing steel. From corrosion fbe coatings are thermoset polymer coatings.
