Can Epoxy Coated Rebars be Used Instead of SS 316L in Expansion Joints in Concrete Structures?

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.
It can also be used instead of SS 316L in expansion joints but we need to take some precautions.

Epoxy coated rebar:
yes, we can definitely use epoxy coated rebar instead of ss316l in case of an expansion joint in the concrete.
Epoxy coated rebar is an excellent abrasion resistive material.
It is a high-quality product. It should be more ductile and strength able so that its durability is Greater.
A double Base week and placed in the Travels joints of the concrete floor and the Play a part in the transfer of partial shear load from lower to the adjacent floor
The double bar can also allow axial thermal expansion as well as contraction of the concrete slab along the shared axis.
Thank you.

Definitely yes- But some precautions must be taken from your side when handling on construction site
Epoxy coated rebars get scratch on-site and then start degrading. This causes affects your project economically.
But, yes can use Epoxy bars instead of SS 316L in expansion joints.

Yes – as long as your construction specification permits you to use the substitution. You have to convince the design engineer and obtain his consent and explain why and how epoxy coated bar is equal or better that SS316L without compromising the overall performance and life.
