What Is Rebar? Steel Types, Carbon Content & Uses

Rebar, short for reinforcing bar, is a steel reinforcement material used to strengthen concrete structures. Because concrete is strong in compression but weak in tension, rebar helps improve tensile strength and structural stability in foundations, slabs, walls, bridges, and other construction applications.

Most rebar is made from carbon steel, but the exact material can vary depending on project requirements. Common options include carbon steel rebar for general construction, stainless steel rebar for corrosive environments, and other specialty grades for demanding applications. Understanding what rebar is made of helps buyers, contractors, and engineers choose the right balance of strength, durability, and cost.

Concrete reinforcement is crucial for improving the long-term performance of slabs, foundations, and structural elements. Two of the most common options are rebar and welded wire mesh (often called wire mesh

In the world of construction, the debate of fiberglass rebar vs. steel is becoming increasingly common. While steel has been the traditional king of reinforcement, fiberglass (GFRP) is challenging the status quo with superior longevity and strength-to-weight ratios.

Are you wondering "is fiberglass stronger than steel?" or comparing the long-term costs? This 2025 guide breaks down the key technical differences to help you choose the right material for your project.

Quick Comparison: Fiberglass (GFRP) vs. Steel Rebar

Rebar steel (reinforcing bar) is the backbone of concrete construction. But when engineers calculate load capacities, they don't guess—they look for specific numbers. One of the most common questions we get is: "What is the tensile strength of rebar?"

If you are looking for a quick answer or a rebar tensile strength chart, you are in the right place. Below, we break down the critical differences between Grade 40, Grade 60, and high-strength options.

The "Grade" of rebar designates its minimum yield strength. Here is the standard ASTM data used in the US:

In 2026, stainless steel rebar typically costs between $3.50 and $8.00 per linear foot, depending on bar size, grade, order quantity and market conditions. For common #4 (1/2 inch) stainless steel rebar, most contractors see prices in the range of $4.50–$6.50 per foot for typical 304 or 316 grades, with premium duplex grades on the higher end.

If you are budgeting for a project, the best approach is to use the ranges below for early estimates and then request an updated quotation based on your exact size, grade and quantity.
