On any job site, your workers are going to find rebar. The rebar used in concrete helps reinforces the structures that were there. Even when it comes to new construction, rebar still serves a purpose. Here are three vital questions about it.

What are the Grades?

The different grades of rebar reflect the varying amounts of tensile strength that they have. Grade 33 is the lowest end of the spectrum, while Grade 40 is even stronger and Grade 60 is close the other end of the spectrum. In other words, it is one of the most durable types. The higher the grade number, the strong the bar is. 

How to Differentiate Them? 

Steel rebar used for concrete working comes in many different grades. That should be expected because every job is different and has different demands on your workers&#; time and energy. Start by inspecting each bar. Look for any stamped combinations of letters and numbers. You should see three characters there. These characters indicate who manufactured it, what grade it is, and that it is made out of steel. This is how it is when you see B65. 

Other numbers and letters mean different things. Higher or lower numbers indicate bar sizes, and paint colors on the ends tell you what you can and can&#;t do. Seeing the same color at both ends means that you cannot weld the bar. On the other hand, red with one different color means welding is possible. The different colors you might see include white, yellow, and green.    

What Difference Does It Make?

You might be wondering why it even matters to continue using rebar for your next set of projects. The stronger bars can hold up more weight and help make the buildings more stable. Holding up a patio will take lower tensile strength than reinforcing a roof. It all comes down to how the rebar will be used and what type of structure to concrete is supposed to be used for as well. Getting the right bars will make a difference, so don&#;t overlook how important it is.

When you&#;re getting ready to start a construction project, the many steel rebar grades that are available on the market can be confusing at best. But what&#;s the difference between the many grades? How do you tell them apart? Does it really matter which kind you use in your next project? Here&#;s a quick glance at these questions and more to help get you started for your next project.

The Many Different Rebar Grades and How To Them Apart

What are the different rebar grades?

Rebar is graded to show the amount of tensile strength it has in terms of pounds per square inch. Grade 33 starts out the low end of strength, with strength increasing as the grade number gets bigger. Grade 40 has a minimum yield strength of 40,000 PSI and a minimum tensile strength of 60,000 PSI. By comparison, grade 60 rebar has a minimum yield strength of 60,000 PSI and a minimum tensile strength of 90,000 PSI.

How can I tell the different steel rebar grades apart?

There are a few ways to tell the difference between grades of steel rebar. One of the easiest is to look for the stamped numbers and letters between the lines on the rebar. This may include a set of three characters, such as B6S. This means that the manufacturer is shown by the letter B, it&#;s grade 60 rebar and it&#;s made of steel. If there&#;s another number there, that may show rebar sizes. Another way to tell is by the lines running between the outside ribs. If there is no line, the bar is a grade 40 rebar. If there is a line there, it&#;s a grade 60 rebar. The third way to tell is by looking for paint at the ends of the rebar. If it&#;s the same color on both ends, the rebar isn&#;t weldable. But if one end is red and the other end is a different color, it can be welded. In this system, white is grade 33, yellow is grade 40 and green is grade 60.

How much does it really matter if I get the right grade of rebar?

Your project&#;s reinforcing bar determines how much weight it can bear. The type of rebar is very vital if you have a project that will bear a higher amount of weight. For small home improvement projects, such as a simple concrete patio, a lower tensile strength rebar constructed of plain carbon steel in a grade 33 can work fine. You wouldn&#;t want to have that holding up your roof in earthquake country.

By understanding the differences between the different rebar grades, you can much more easily find the right type for your project or upgrade to better structural strength for a little extra insurance. But now that you know what rebar grade you need, do you have the tools to get the job done right?
