PC Strand | Concrete Reinforcing Products
PC Strand. CRP imports prestressed concrete strand (PC strand) from locations worldwide including Europe, Asia, and Africa. This allows our customers the best quality product at the most affordable prices. PC strand is a high carbon, seven—wire steel product used to impart compression forces into pre-cast structures.
Types of Prestressing Systems and Anchorages in
In prestressed concrete structures, prestress is introduced by stretching steel wire and anchoring them against concrete. Therefore, the prestressing systems should comprise essentially a method of stretching the steel and a method of anchoring it to the concrete. Different systems are adopted for pre-tensioning and post tensioning.

What is Prestressed Concrete? (with pictures)
Prestressed concrete is a combination of high strength concrete and steel strands. This combination makes a very strong structural material that is used in the building of roof slabs, bridge girders and railroad ties. Prestressed concrete was invented and patented in 1886 by Henry Jackson, a San Francisco engineer.

Difference Between Prestressed Concrete & Reinforced
Reinforced concrete and prestressed concrete both have steel bars or wires embedded to bolster the material's weakness under tension, but the types of steel and the uses of the concrete are different. Concrete reinforcing steel is either solid bars with ribs on them, referred to as reinforcing bar or rebar, or a wire or metal mesh.
