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.

What are epoxy coated rebars?

Epoxy Coating of Steel Reinforcement It is important to use epoxy coated rebar to protect steel from corrosion. 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.

What are the disadvantages of epoxy?

Epoxy primer actually seals out the oxygen from the metal, leaving no chance of rust or corrosion forming on the surface like some cheap spray bomb type primers. Two-part epoxy primers go one step further by including zinc phosphate, which increases its corrosion-inhibiting properties.

How long does epoxy coating last?

Typically, epoxy flooring lasts 2 to 3 years in heavy traffic. Commercial properties—like garages, restaurants, or factory spaces—with lots of daily foot traffic can expect this experience. However, with proper care and maintenance, your epoxy flooring may last much longer.
