Your Local Choice for Post-Tension Services in Houston TX; Dallas, TX; and Beyond
Reinforcing steel (rebar) is used in bridges, buildings, skyscrapers, homes, warehouses, and foundations to increase the strength of a concrete structure. This is because concrete is weak in tension, while steel is strong in tension and compression. Our post-tension services provide the highest quality rebar supply for all commercial and residential concrete reinforcement projects in the Houston and Dallas, TX areas.
Advantages of Steel
- It can be bent after being manufactured. This simplifies construction and ensures the rapid delivery of fabricated materials.
- It is robust and able to withstand the rigors of construction.
- Reinforcing steel can be recycled at the end of the structure design life.
- Reinforcing steel does not need to be tied directly to the formwork and does not float in concrete.
Why Should You Use Concrete Reinforcement for Construction?
In the mid-1800s, builders began including steel in their concrete constructions to carry the tension forces. Since then, reinforced concrete has become a popular building material for many contractors. Why are so many builders using it?
Thermal expansion is similar for concrete and steel, so when reinforced concrete freezes or gets hot, the two materials contract and expand similarly. If they didn’t, the combination would tear itself apart over time.
The bond between reinforcing steel bars (rebar) and concrete is strong and efficient. Rebar has surface deformations that will further improve that bond. Due to the strong bond, concrete effectively transfers stresses to the steel and vice versa.
When cement paste contacts steel rebar, it forms a non-reactive surface film that inhibits corrosion. This passivation process helps to keep rebar from corroding inside the reinforced concrete.
The location of the rebar in the structure depends on the use. Simple beams and slabs often have rebar only on the side. When a continuous beam spans the top of columns, the tension is at the top of the beam, so rebar is needed at the top of the beam over column supports.
