What Is #4 Rebar?
#4 rebar is a steel reinforcement bar that is commonly used in concrete construction. It is made of a deformed wire that is welded to a plain wire.
The deformed wire gives the rebar added strength and resistance to bending. This makes it ideal for use in concrete structures that are subject to high loads or stress.
#4 rebar is available in a variety of sizes and lengths to suit any construction project. It can be cut to length with a variety of tools, and is easy to work with.
