Asia is witnessing rapid growth in transportation and infrastructure development, with governments investing heavily in highways, expressways, railway corridors, metro systems, flyovers, ports, airports, and smart city projects. As bridge structures become longer and more complex, the demand for reliable structural protection systems continues to grow.
One of the most critical bridge safety components used in modern infrastructure is the Shock Transmission Unit (STU), also known as a Lock-Up Device (LUD). These devices are designed to allow slow structural movements caused by thermal expansion while instantly resisting sudden dynamic loads generated by earthquakes, braking forces, impact loads, and extreme environmental conditions.
JK Prestressing Co. is a trusted manufacturer and supplier of high-performance Shock Transmission Units for bridge and infrastructure projects throughout Asia, serving contractors, consultants, government agencies, and EPC companies involved in transportation and civil engineering developments.
Our Shock Transmission Units are supplied for projects throughout:
India, Bangladesh, Nepal, Bhutan, Sri Lanka, Pakistan, Maldives, Afghanistan
Myanmar, Thailand, Vietnam, Malaysia, Singapore, Indonesia, Philippines, Cambodia, Laos, Brunei
China, Japan, South Korea, Taiwan, Hong Kong
Kazakhstan, Uzbekistan, Kyrgyzstan, Tajikistan, Turkmenistan
United Arab Emirates (UAE), Saudi Arabia, Qatar, Oman, Kuwait, Bahrain, Jordan, Iraq
A Shock Transmission Unit is a specialized bridge component designed to transfer sudden loads across bridge structures while permitting slow movements caused by temperature variations and long-term structural behavior.
