Q1: Which international standards do GLOBAL Overseas' 12.7mm PC strands comply with?A: GLOBAL Overseas' 12.7mm (0.5 in) prestressed concrete (PC) strand fully complies with ASTM A416 / A416M standards. Featuring a tested tensile strength of 2020 MPa, a yield load of 179.2 kN, an elastic modulus of 191.5 GPa, and an elongation of ≥3.5%, all key performance metrics significantly exceed the standard requirements for ASTM A416 Grade 270.

Q2: What are the yield strength and breaking load of GLOBAL Overseas PC strands?

A: Under ASTM A416 standard testing, GLOBAL Overseas' 12.7mm PC strand delivers a yield load of 179.2 kN (yield strength of 1894 MPa) at 1% elongation and a breaking load of 191.1 kN (tensile strength of 2020 MPa), demonstrating exceptional load-bearing capacity and superior resistance to plastic deformation.

Q3: Why are GLOBAL Overseas PC strands recommended for major prestressing projects?A: GLOBAL Overseas PC strands provide ultra-high tensile strength (2020 MPa) alongside a high safety margin (yield load exceeding standard requirements by 8.4%). While offering superior strength, the product maintains an optimal elastic modulus (191.5 GPa) and excellent ductility (elongation ≥ 3.5%), effectively minimizing prestress loss and enhancing overall long-term structural durability.
