With what material must epoxy coated rebar be tied?

Epoxy coated rebar is designed to provide enhanced corrosion resistance, especially in environments where concrete is subject to moisture and chemicals that can cause rusting. To maintain the integrity of the epoxy coating and avoid compromising its protective qualities, it is essential to use coated tie wire when securing this type of rebar.

Coated tie wire is specifically designed to mitigate any potential damage to the epoxy layer during installation. It ensures that the connection between the rebar does not scrape or strip away the protective coating, which could expose the steel to corrosion. Other types of materials, such as standard wire, plastic tie wire, or steel wire, may not provide the same level of protection or might interact adversely with the coated surface, potentially leading to future performance issues.

Using coated tie wire aligns with the best practices in construction where epoxy coated rebar is utilized, thereby safeguarding the rebar's performance over its intended lifespan.
