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.

Can you bend epoxy coated rebar?

Bending of galvanized rebar can cause flaking of the galvanized coating in the bend area. Special precautions are re q u i red when bending epoxy – coated bar to prevent coating damage. Bending should only be perf o rmed around a smooth, nonabrasive die to avoid damage to the epoxy coating.

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.

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.

How long does epoxy last for?

Can you bend grade 60 rebar?

Field bending or straightening can be done by placing a steel pipe over the bar and pulling on the bar. Smaller bars can be pulled with manual effort. A series of bending and straightening tests on Grade 60 reinforcing bars was conducted for the CRSI Technical Committee of the Associated Reinforcing Bar Producers.

Do you need to epoxy rebar?

Epoxy -coated rebar prevents corrosion and the problems that it causes. Manufacturers cover the entire bar of rebar in a coating of epoxy. This water-impermeable layer minimizes the chances that corrosion will take hold of the rebar.

What is the difference between #3 and #4 rebar?
