What is the main difference between Type 1 and Type 2 epoxy-coated rebar?

The main difference between Type 1 and Type 2 epoxy-coated rebar lies in the level of protection they provide against corrosion. Type 1 rebar is coated specifically to prevent corrosion, which is essential for reinforcing bars exposed to harsh environments. Type 2 rebar not only serves the same purpose of preventing corrosion but also features a thicker coating. This thicker coating enhances its ability to resist corrosion over time, making it more suitable for applications where higher durability and resistance are required.

Thus, the distinction comes down to the thickness of the epoxy coating and the level of protection against environmental factors. This understanding is crucial for ironworkers when selecting rebar for specific applications, as the environment and longevity requirements can significantly influence the choice of materials.
