Manual for Design and Detailing of Reinforced Concrete

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 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.

PC steel bar / PC steel strand Business MAYATEC

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 Lintels Specifiers Handbook

As the prestressing wires of a Naylor Lintel are tensioned in a fabricated steel mould to specific tolerances it is not possible for the structure wires to be misplaced or miss-aligned. This can occur in precast sections that rely on the placement of individual bars fixed with steel or plastic spacers often in timber moulds that have a limited Product Research - Prestressed Concrete Strand,Steel Bar Spiral rib series PC products are typical of our research technique; the continuous development of the new products such as the PCCP wire, high property PC bar, and the intensive processing steel enables Silvery Dragon to obtain a high evaluation in the market.
