Standard Specification For Steel Strand, Uncoated Seven-Wire For Prestressed Concrete

1.1 This specification covers two types and two grades of seven-wire, uncoated steel strand for use prestressed concrete construction. The two types of strand are low-relaxation and stress-relieved (normal-relaxation). Low-relaxation strand is to be regarded as the standard type. Stress-relieved (normal-relaxation) strand will not be furnished unless specifically ordered. Grade 250 [1725] and Grade 270 [1860] have minimum tensile strengths of 250 ksi [1725 MPa] and 270 ksi [1860 MPa], respectively, based on the nominal area of the strand.

1.2 A supplementary requirement (S1) is provided for use where bond strength testing of 0.600-in. [15.24-mm] diameter Grade 270 [1860] strand for applications in prestressed ground anchors is required by the purchaser. The supplementary requirement applies only when specified in the purchase order.

1.3 This specification is applicable for orders in either inch-pound units (as Specification A416) or in SI units (as Specification A416M).

1.4 The values stated in either inch-pound units or SI units are to be regarded separately as standard. Within the text, the SI units are shown in brackets. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the specification.

Prestressed Concrete Steel Wire Spiral Ribbed

PC Wire (also referred to as Prestressed Concrete Steel Wire) is high tensile, low relaxation steel wire made from high-carbon steel and widely used for prestressed and post-tensioning technology in various shapes of PC structures.

PC Steel Bar

Prestressed concrete steel bars, referred to as PC steel bars, are widely used because of their high strength and toughness, low relaxation, strong bonding force with concrete, good weldability, upsetting, and material saving (for example, φ11mm PC steel bars can replace φ20mm hot-rolled steel bars). Used for high-strength pre-stressed concrete centrifugal pipe piles, electric poles, viaduct piers

Important Facts About PC Bar Used in Spun Pile

Pre-stressed Concrete Steel Bar (PC bar) is one main component used in manufacturing of concrete spun piles other the concrete itself. Made of low carbon steel, PC bar is manufactured by using high frequency quenching and induction heat treatment process to gain the utmost mechanical property of high tensile steel bar.
