Other prestressing steel that is occasionally used includes three-wire
1.1 This specification covers Type I and Type II high-strength steel bars intended for use in prestressed concrete construction or in prestressed ground anchors. Type I bars have a plain surface. Type II bars have surface deformations. Bars are of a minimum tensile strength level of 150 000 psi [1035 MPa].

Unless otherwise stated, the general provisions and dimensioning of steel bars are based on ribbed steel reinforcing bars with 500fy N/mm 2. Design charts for beams, columns and walls are based on the more rigorous stress strain relationship of concrete comprising a rectangular and a parabolic portion as indicated in Figure 3.8 of the Code. Nucor's new rod mill begins shipments American Metal Nucor plans to move up the product mix and produce wire rod for prestressed concrete (PC) strand by early 2014, AMM understands. The Charlotte, N.C.-based steelmaker confirmed that customers have begun receiving wire rod from the mill. One rod buyer said he had some material in his yard that he was getting ready to test.
PC beams:The PC beams had spans of 10 m and 20, uniform superimposed gravity dead load of 2 KN m'-1 in addition to the own weight of the beam, uniform live load of 3 KN m-2, f c ' = 41.4 MPa, f y = 410 MPa, yield strength of the steel tendon f yp =1517 MPa, ultimate strength of the steel tendon f up =1862, the initial prestressing before PC Wire with Prestressing Force for Concrete StructuresPC Wire with Different Surface Treatment for PC Structure. PC wire, also called PC steel wire, is made of carbon steel and used in concrete structures.According to the surface treatment, it is classified into plain PC wire, indented PC wire and spiral ribbed PC wire.Before using, through pre-tensioning or post-tensioning method, PC wire has a kind of prestressing force.
Concrete Pile. A lot of these use a technique called prestressing. It provides pre-tensioning force to the properties of concrete that are strong in compression force but weak in tensile force, making it stronger and more durable. Prestressed concrete (PC) is made into concrete. The PC products we handle are essential to provide that tension.

horizontal steel and vertical tie-bars. Horizontal joint reinforcement consists of dowels projected from the panels and the hairpin hooks site-welded to the dowels; the welded length of the lapped bars depends on the bar diameter and the steel grade. Vertical tie-bars are designed for tension forces developed at the panel intersections.

Prestressed Concrete BridgesPrestressed concrete is created through one of two processes:post-tensioning and pretensioning. Post-tensioning. The simplest type of early prestressed-concrete beams used steel cables to tightly tie together a row of concrete blocks end to end. This is like lifting a
