What is epoxy coated rebar used for?

Epoxy coated rebar or corrosion-resistant rebar is used instead of conventional reinforcing bars to strengthen the concrete and protect against corrosion. The epoxy coating is applied in a factory to the steel prior to shipping to ensure corrosion resistance.

Is epoxy coated rebar being banned?

It is not being banned. Being more selective in its uses yes, but still a very commonly used product.

Does epoxy coated steel rust?

Epoxies are excellent at repelling water and moisture. Epoxy coating for steel is designed to mitigate these factors by introducing a protective layer that provides strong resistance to corrosion, degradation, and impact.

What is epoxy coated steel?

What Is Epoxy Coating? Epoxy coating is a thick, protective material used to preserve carbon steel tanks from any exterior deterioration. Although Zwirner Equipment uses epoxy coating for carbon steel tanks, it is well known to be used for industrial concrete floors because of its extreme durability.

What is wrong with epoxy coated rebar?

Laboratory tests and field inspections indicate that epoxy – coated rebar in a marine substructure application is more susceptible to corrosion than bare bar. The underlying clean bright metal, which does not passivate, as does bare steel when in contact with cement, is highly susceptible to corrosion.
