We are honored to announce that China’s FAST (Five-hundred-meter Aperture Spherical radio Telescope) project has won the First Class Prize at the National Science and Technology Progress Award! As a core contributor, OVM is proud to have delivered the key technological breakthroughs that made this engineering marvel possible.

Building the world’s largest single-dish radio telescope meant solving challenges never before faced in civil engineering:

 

  • Extreme Fatigue Demands: FAST’s dynamic reflector frequently switches between spherical and paraboloid shapes. This required cables capable of withstanding a 500 MPa stress range across 2 million fatigue cycles—2.5 times the limit of conventional bridge cable standards. Standard existing cable structures failed in tests at fewer than 100,000 cycles.
  •  
  • Full Technological Independence: Partnering closely with the National Astronomical Observatories of China (NAOC), our R&D team pioneered proprietary composite anchorage technology and an integrated cable system. This breakthrough passed the rigorous 2-million-cycle test, filling a global gap in ultra-high-performance prestressing systems.
  •  
  • Millimeter-Level Precision: Overcoming complex high-altitude conditions, our field team installed 8,895 high-strength cables with a positioning accuracy of ±1mm, ensuring flexible and precise deformation of the telescope reflector.


 

This landmark achievement represents OVM’s 6th National Science and Technology Progress Award and our second First Class Prize (2014 & 2025)—a strong testament to our technical expertise in prestressing engineering.

Today, the core technologies forged through the FAST mega-project are actively powering innovations in renewable energy, marine engineering, and mega-infrastructure projects worldwide.

Moving forward, OVM remains committed to driving engineering progress with self-developed technology, delivering reliable solutions for global high-end infrastructure.
