Reinforcing Steel

It’s completely invisible. You never actually see it because it’s always buried. Concrete reinforcing steel is used in bridges, buildings, skyscrapers, homes, warehouses, foundations and roads to increase the strength of the concrete and ultimately help hold up the structures. While concrete alone is strong, reinforcing steel significantly increases the strength of concrete in an economical and safe manner. Reinforced concrete is also considered environmentally friendly as the steel is made from 100% recycled scrap. At demolition, the reinforcing steel and the concrete are separated and recycled for re-use.

Reinforcing Bars: Embedded "Strength" of Reinforced Concrete

Steel Reinforcing bars are produced by pouring molten steel into casters and then running it through a series of stands in the mill, which shape the steel into reinforcing bars. The cross hatchings, called "deformations," help secure the steel and transfer the load between it and the concrete.

For buildings, bridges, highways, and runways, the cast-in-place concrete body and shop-fabricated steel musculature of reinforcing bars work in tandem to create one of the most durable and most economical composite materials.

Reinforced concrete is composite material. The concrete provides the material's compressive strength, while the steel — in the form of embedded reinforcing bars — provides tensile strength.
