About 420s steel rebar

Types of 420s Steel Rebar

There are several types of 420s steel rebar. These rebars are categorized based on specific mechanical properties such as tensile strength and yield point among others.

  • Grade 420s fiberglass rebar

    This is a high-strength type of steel that is impervious to corrosion due to its fiberglass composition. This makes the barrier lightweight, thus easy to work with. It is also non-magnetic, making it ideal for applications in construction where magnetic interference could pose a problem. It is mostly used for reinforcing concrete in chemical plants, marine structures, and other environments prone to corrosion.
