#4 Reinforcing Bar

Harris Supply Solutions offers #4 reinforcing bar, also called #4 rebar, which is made from a sturdy composite of carbon steel. This common, high-grade rebar has widespread applications in the residential and light commercial construction industries. In particular, #4 reinforcement steel is used to pave roads and highways, and in certain climates, it can also be used to build swimming pool frames. It is often trusted as a strengthening material in slabs, piers, columns, and walls. This 1/2 inch rebar grade is known as “13MM" in the metric system.
