What Is The Purpose Of Rebar In Construction Projects?

Business

Rebar is a word that gets thrown around a lot when it comes to construction projects. It’s easy to misunderstand what it means. What exactly is rebar? Read the article below to understand the basic nature and purpose of rebar in construction.

Rebar is a Type of Steel Reinforcement

A rebar is essentially a bar of steel. The word “rebar” is just a shortened term for reinforced bar of steel.  Rebar steel offers reinforcement for particularly concrete structures. This reinforcement is what prevents concrete structures from cracking up and falling apart.

Rebar is necessary for reinforced concrete to create the right amount of tension to hold structures. You will find rebar structures with certain patterned on the surface. The patterns offer better bonds with concrete to provide reinforcement.

Rebar is usually a bar of steel but can be a type of mesh too. Builders use industrial stirrup bender equipment to design and manufacture rebar structures for individual projects.

Benefits of Rebar Reinforcement

Here’s what rebar offers builders:

  • Rebar is one of the best ways to prevents cracks and shrinkage in concrete.
  • Ribbed rebar offer concrete structure better grip and thus strength.
  • Makes structures stronger in general.
  • Protects some structures against shifting environmental conditions.

Types of Rebar

Rebar comes in different sizes and shapes to suit various environments and projects. Here is a basic overview of different types of rebar you will usually find in construction sites:

Stainless steel: This is the most common type of rebar used in projects. You will most likely find stainless steel rebar in buildings near the coast. Builders prefer this material for its anti-corrosive effects. Stainless steel is usually substituted when rebar with zinc can’t be used.

Glass fibre: A relatively new material for rebar, glass fibre is used to provide concrete structures with top-notch tensile strength. You may know of this material as GFRP, a reinforced type of polymer. Glass fibre rebar is available as long rods or sticks.

Carbon steel: This type of rebar is quite common in many construction projects. Carbon steel is highly budget friendly, and is the traditional material for rebar.

Galvanized rebar: The galvanized versions of rebar are coated in zinc. This type of rebar is usually used to prevent corrosion. It’s like stainless steel, but is highly environment specific. You may find galvanized rebar in structures inland and away from coastal areas. Galvanized rebar can be constructed using several different processes, including cold plating and hot plating.

European rebar: Usually made in Europe, these rebars are made from manganese rather than steel. These rebar are economical, but aren’t suitable for areas that experience extreme environmental conditions like earthquakes.

Epoxy: Epoxy coated rebar are a modern addition. Epoxy is a coating material that can prevent corrosion. It’s often used as a budget-friendly alternative to zinc coated or stainless steel rebar. Though affordable, epoxy coating can’t withstand some environments, especially the ones where the sub-grade can shift.

There are many other types of rebar, but above are the most used and also the most modern additions.

Now you should have a better understand of what rebar is, and why it’s important for your next concrete construction project. Do make sure you choose the right material and machinery for design rebar for your project.
