Rebar is a necessary component of many construction projects. Because concrete can be cracked relatively easily by bending and twisting, metal rebar is used to reinforce a structure’s tensile strength. But just like the buildings it’s used in, rebar comes in many varieties.
5 Types of Rebar & Their Attributes
1. Carbon Steel
Carbon steel rebar, or “black bar,” is used in a wide range of structures both big and small. While it provides tremendous tensile strength for its cost, it also corrodes and expands somewhat when saturated. This expansion can cause the surrounding concrete to crack, making black bar ill-suited for areas of high humidity or moisture saturation.
2. Galvanized
This steel rebar is coated with a layer of protective zinc. While it is more resistant to corrosion than black bar, it is also considerably more expensive. With the added layer of metal on top of the steel, its sturdy build and abrasion-resistant surface make it suitable for transport and handling without any extra precautions.
3. Stainless Steel
Stainless steel is by far the most corrosion-resistant rebar available, and it can handle more stress before sustaining damage. Furthermore, it can be bent at construction sites. It is, however, the most expensive type of reinforcement by far.
4. European
Made from manganese, European rebar isn’t as resistant to bending as other types. This weakness makes it ill-suited for environments that experience earthquakes or structures that heavily rely on the strength of rebar additions. It is, however, very affordable choice when compared to other types.
5. Epoxy-Coated
This is black bar that has been coated with a corrosion-resistant epoxy, making it up to 1,700 times more resistant than untreated options. The coating, however, is very fragile. As it is damaged, the corrosion resistance is reduced.
