#3 or #4) instead of the “soft” metric sizing (ie. In the United States, we use the imperial bar size (i.e. There are different sizes of rebar also, and each size has a number. Plain rebar obviously doesn’t have the ridges and is used when the steel must “slide,” such as in bridges or highways. Some rebar comes as “deformed” versus “plain.” Deformed means they have ridges in their structure that help with reinforcing the concrete. Glass-Fiber-Reinforced- Polymer: Also called “fiberglass rebar.” this is made of a resin wrapped with fiberglass that has higher tensile strength than steel, will never corrode, and is very expensive.Stainless Steel Rebar: This is the most expensive rebar, but it’s also very strong and resistant to corrosion.Galvanized Rebar: This rebar is also very resistant to corrosion, much like the epoxy-coated rebar, but it is more expensive.Epoxy-Coated Rebar: Also known as “green bar” and is used mainly in bridges, or humid environments since it is very resistant to corrosion.It doesn’t withstand extreme conditions, and shouldn’t be used where stronger rebar is available. European Rebar: This is a cheap type of rebar made from manganese.It, unfortunately, corrodes easily compared to other rebars. Tempered Steel Rebar: Also known as “carbon steel” rebar or “black bar,” this is the most common type of rebar out there.SourceĪlso read: What Concrete Requires No Reinforcement? Types Of Rebar In one comparison, the minimum cost for wire mesh is $0.14 per square foot while rebar’s minimum cost is $0.75 per square foot. In terms of cost, rebar tends to cost more than 5x the price of wire mesh. Rebar commonly comes in 10 to 12mm thickness while remesh comes in 4mm thickness.
Rebar is designed to prevent structural or foundational cracking while wire mesh is designed to prevent cracking in smaller projects and not suited for a heavyweight, for example, in the foundation of a large building. It is an option, however, when considering how large your project is and how much reinforcement the concrete needs. Mesh is not as strong as rebar since the wires are not as thick. It is made out of galvanized stainless steel wires. On the other hand, wire mesh (also called reinforced welded wire mesh, or sometimes “remesh”) is a sheet-like material formed into a grid-like pattern that is added to concrete to help support concrete, much like rebar. It is typically used in larger projects where lots of concrete needs lots of strength to keep it from cracking or breaking apart. All rebar is steel and is used especially in concrete or masonry projects to add strength to concrete. Rebar is short for reinforcing bar and is also known as reinforcing or reinforcement steel.
