What are Rebars (Steel Reinforcement Bars ) | Types and Grades of Steel Reinforcement
What are Rebars ?
Rebars also know as Steel reinforcement bars are specific bars that are used to improve the tensile strength of the concrete as concrete alone is very weak in tension, but is strong in compression.
Steel bars has the best reinforcement properties for concrete structurally than any other type of reinforcement material. It is because steel offers significant strength of its own.
Steel bars can bend without breaking under stress or pressure. More so, the steel thermal coefficient which is, steel bar rate of expansion and contraction when subjected to heat or cold , is almost the same to that of concrete.
Once steel is embedded, reinforcement will expand and contract together so that the concrete maintains cohesion.
A reinforcement material with different thermal coefficient would result in broken concrete rather quickly.
Types of Rebars
These are the common types of rebars used in construction for the reinforcement of concrete:
- Threaded rebar
- Tempered steel rebar
- Basalt rebar
- Stainless steel rebar
- Epoxy coated rebar
- Fiberglass rebar
- Welded Wire Fabric
