OVM is a leading manufacturer and a specialist contractor in China and worldwide in the field of prestressing and other specialized construction techniques. OVM System works successfully on challenging projects, including bridges, buildings, tunnels, ports, dams and nuclear power plants. OVM designs their systems and manufactures them in their own factory in China, which allows them to apply a strict quality control system to their products throughout the manufacturing process. In this way, OVM has positioned itself as a leading preload supplier, with a strong reputation for high quality and reliability.

With more than 40 years of experience in the field, OVM has developed into one of the leading manufacturers and specialized contractors in China. OVM’s ownership structure is integrated into various projects, from bridges to nuclear power plants. On a strategic level, OVM constantly invests in research and development to stay at the forefront of the industry and continuously provides more efficient and effective solutions for clients around the world. The production program includes prestressing systems, cable systems, construction solutions, bearings and expansion joints and monitoring systems. The entire product range is certified in accordance with ISO9001-2008 and meets the requirements of standards established by international organizations, including: – ETAG 013, AASHTO LRFD, BS, ASTM, JIS, etc.

PRE-TENSION SYSTEM

OVM invests part of its annual turnover in technical research and development in order to remain an industry leader. The company owns a national technology center and postdoctoral research workstation and maintains close relationships with numerous universities and institutions throughout China; this leads to OVM registering many technical patents.

The company focuses on the development of superior prestressing technology, building a renowned brand in the field of construction. As the largest supplier in China, OVM has a wide range of prestressing systems including but not limited to: prestressing systems, cable systems (MS & PWS cables) and construction solutions (incremental launch, turning and heavy lifting).

The excellence of OVM products is confirmed and certified by ISO9001- 2008, Quality Management System by BSI and CQC. In addition, our products meet all major standards such as AASHTO, ASTM, BS, EN, ETA, FIP, GB, JIS and PTI. Moreover, OVM conducts extensive testing with international independent testing organizations to further improve its products on a technical level.

PRE-LOADING – BRIDGES

Post-tensioning (PT) is a dynamic technology that enables economical construction of high-quality bridges. PT can be adapted to be implemented in different terrain conditions and bridge lengths. Prestressed bridges have a high degree of internal durability, can be constructed relatively quickly, have a lower risk of cracking, have a smaller construction depth and have low maintenance costs.

In addition, these bridges can be built without disturbing the relief beneath the bridge – allowing for longer spans (~ 92m) and shallower girders. Better ductility, seismic performance and aesthetics are common benefits of using prestressing.

PRE-STRESSING – BUILDINGS

Prestressing is a solution that can be integrated into different types of buildings, from residential buildings to hotels. PT in buildings leads to greater flexibility in design and requires less reinforcing steel than conventional methods to achieve the same strength levels. Prestressed concrete drastically reduces floor-to-floor height compared to structural steel, thereby reducing facade, HVAC, electrical, plumbing and vertical transportation system costs, resulting in significant savings.

Integral, prestressed buildings have superior structural integrity compared to precast concrete structures, have better crack control, have lower overall building mass, and have faster floor construction cycles—all without sacrificing building aesthetics.
