UNIVAC Achieves Breakthrough in Prestressed Steel Strand Technology, Expands Global Market Reach

Univac New Materials Tech. Manufacturing Co., Ltd., a leading manufacturer for construction materials, our PC products branch factory has successfully developed a new high-performance **1×3-6.5mm prestressed steel strand with a tensile strength exceeding 1800MPa, meeting stringent ASTM A416 and other international standards. This milestone follows the company’s earlier success in producing 1×7-7.94mm strands at 1860MPa, further solidifying its position in the global high-end construction materials market.

Advanced Product Line for International Standards

With an expanding portfolio, UNIVAC now offers a comprehensive range of prestressed steel strands, including:

-1×3-6.5mm (1800MPa+) Newly developed for specialized applications

-1×7-7.94mm (1860MPa) Proven in high-demand projects,also 9.3mm, 9.53mm, 11.11mm, 12.5mm, 12.7mm, 12.9mm, 15.2/15.24mm, 15.7mm, 17.8mm etc.

These products comply with major international standards such as:

✔ **ASTM A416 (US)**

✔ **PrEN10138 (Europe)**

✔ **BS 5896 (UK)**

✔ **AS/NZS 4672.1 (Australia/New Zealand)**

✔ **XP A35-045 (France)**

✔ **NBR 7483 (Brazil)**

✔ **MS 1138 (Malaysia)**

✔ **JIS G3536(Japan)**

✔ **KS D7002(South Korea)**

✔ **ISO 6934-4 (Global)**

This versatility ensures compatibility with **precast hollow-core seismic slabs, bridges, high-rise buildings, and infrastructure projects worldwide**.

Meeting Global Demand with Superior Performance

The newly developed **1×3-6.5mm strand** has already been supplied to an international client producing concrete hollow-core seismic precast panels, demonstrating:

✅ **Ultra-high tensile strength (1800MPa+)** – Exceeding typical industry requirements

✅ **Superior ductility and corrosion resistance** – Ensuring long-term structural integrity

✅ **Strict adherence to US/EU/ISO standards** – Facilitating global procurement

"By introducing this new specification, we’re addressing the growing demand for lightweight yet ultra-strong prestressed solutions in seismic zones," said Mr.Wang, Marketing &Technical Supervisor at UNIVAC. "Our ability to meet diverse international standards positions us as a trusted partner for global infrastructure projects."

Strengthening International Market Presence

This achievement reinforces UNIVAC’s strategy to:

Penetrate high-value markets in North America, Europe, and Oceania

Support critical infrastructure such as earthquake-resistant buildings and long-span bridges

Enhance customer satisfaction through reliable, high-performance materials

With a strong R&D focus and commitment to quality, UNIVAC continues to set new benchmarks in the prestressed steel industry, empowering engineers and developers to build safer, more durable structures worldwide.
