Choosing the Right Type of Rebar for Your Project

You might be overseeing the foundation work for your own home or perhaps you’re a civil engineer that’s in charge of a construction project for an important client. Regardless of whether it’s your first time or hundredth time, you’ll most likely go through the same rigorous procedure when trying to pick the right type of rebar for your particular project.

Rebar comes in different types, each having their own unique properties and their pros and cons. So when you’re picking the right type, consider what each can offer you. Here are six of the most popular variants:

Carbon Steel Rebar

Steel is the popular choice in the construction industries. It can be found inside the structures of the smallest studio apartments to the tallest skyscrapers. Out of its several variants, carbon steel (or ‘black bar’ as it is often referred to) is the most commonly used.

Carbon steel is preferred for its incredible strength, high elasticity and ductility. In addition, it can withstand temperature of around 1400 degrees Celsius, making it a very heat resistant material. This type of steel comes in three sub-variants, depending on the amount of carbon contained: low carbon, mid carbon and high carbon. Each one of these has varying levels of the same properties. For example, high carbon has the greatest tensile strength out of all, following heat treatment.

However, carbon steel rebar is not too strong to be cut in order to meet varying project specifications. Often times, specialized rebar cutters are used for this purpose.

The biggest downside of carbon steel rebar is the fact that it is susceptible to corrosion. Hence it might not be suitable for construction projects taking place in locations where the air is consistently very humid.

Manganese Rebar

Commonly referred to as ‘European rebar’, it is known for being easy to work with and for having a low price tag. However, out of all the types in this list, Manganese Rebar rank the lowest in terms of the ability to warp and bend, rendering it rather impractical for construction projects in countries like Japan, where earthquakes are a common occurrence.  

Stainless Steel Rebar

Unlike carbon steel rebar, stainless steel ones are extremely resistant to corrosion. In fact, the latter is around 1500 times more corrosion-resistant than the former, making it the more durable variant. However, the downside of stainless steel rebar is that it’s incredibly costly.

Glass-Fiber-Reinforced-Polymer Rebar

GFPR Rebar has actually been in production since the 1960s. However, it didn’t become a popular choice until twenty years later, when the Japanese used it for a bullet train construction. GFPR rebar have an incredible amount of useful features. For instance, it is several times lighter than steel rebar while also maintaining a higher tensile strength. It is also a very resistant material. For example, it’s resistance to corrosion means that it has a lifespan that can exceed a hundred years. GFPR rebar are ideal for construction projects in very cold locations due to its ability function optimally even in sub-zero temperatures.

On the other hand, the biggest downside of GFPR rebar is the fact that it is very expensive.

When picking the right type of rebar for your project, consider what requirements need to be met. If you’re not entirely sure which type to go with, we recommend that you ask an expert.
