15.24mm unbonded PC Strand

I. Product Introduction 1. Structure and Composition Construction: Made of 7 high-strength steel wires twisted together, the outer layer is wrapped with a high-density polyethylene (HDPE) sheath, and the sheath and the steel strand are filled with grease to form a "non-bonding" state (that is, there is no bonding between the steel strand and the concrete, and the stress is only transmitted through the anchors at both ends). Specifications: Nominal diameter: 15.24mm (about 0.6 inches), which is one of the common specifications of prestressed steel strands. Nominal cross-sectional area: about 140mm², theoretical weight is about 1.102kg/m. Tensile strength level: commonly 1860MPa (high strength grade, meeting most engineering requirements). 2. Core performance Non-bonding characteristics: The sheath and grease isolate the steel strand from the concrete, allowing the steel strand to slide freely when subjected to force, avoiding uneven stress distribution caused by bonding.
