Introduction of Steel Rebar

A rebar (Reinforcing Bar) is a ferrous steel deformed bar that is used for reinforcement, strengthening & holding concrete. It is usually formed with a surface that is patterned (known as a deformed bar) to make a better adherence to the concrete spilled around it. No specific or special patterns are there for deforming. However, the number, spacing, and height of the marks are standardized and integrated into the primary debar. Also, there are plain bars that are used only in the most specific and definite ways.

Since rebar holds the concrete in a compact state, it is known as a tensioning material. When it comes to compression, concrete is a very tough and strong material, but it almost has no strength when it comes to carrying tensile loads. A rebar is cast in concrete to strengthen concrete and carry the loads.

Production Process of Rebar

  1. Carbon or alloy Steel is melted to a liquid form,
  2. The liquid steel is pulled by a small round opening to form the rebar.
  3. The producer will make the curves and grooves to make sure the metal stays stable inside the structure.
  4. The rebars’ ends are mostly covered by plastic caps to avoid accidental injury to construction workers.

Types of Rebar

  • Carbon Steel Rebars
  • Stainless Steel Rebars
  • European Rebars
  • Epoxy-Coated Rebars
  • Welded Wire Fabric
  • Galvanized Rebars
  • Sheet-Metal Reinforcing Bars
  • Expanded Metal or Wire Mesh Rebars
  • Glass-Fiber-Reinforced-Polymer (GFRP) Rebars

Standards, grades, and size

  • The standards are recognized by the following:
  • The producer’s mill letter or symbol will be rolled into the rebar.
  • The bar size is rolled into the rebar and appears as a digit.
  • The rebar grade will be indicated (40, 60, 75, 80, 100, 120).
  • Obviously, the markings and specifying do more than badge the deformations. Indeed, each marking system shows the details regarding the manufacturing and specifications of each reinforcing bar.
