Concrete Reinforcing Steel Bar

Our Concrete reinforcement bar or rebar (short for reinforcing bar) is hot rolled and used to strengthen concrete under tension in construction. It is incredibly versatile and very long lasting and supplied with heavy ridges to assist in binding the reinforcement to the concrete mechanically - this is commonly referred to as deformed bar.

High Yield Steel Rebar

Typically used to reinforce masonry and concrete, steel rebar counteracts the poor tensile strength of cast concrete. Since steel is a highly versatile material which can be cut and welded to suit almost any need, it is particularly suited to use with concrete in a huge number and variety of construction projects.
