Intelligent Engineering Connections Incorporated

IEC Inc. – Innovating Structural Engineering Connections We are a pioneering company in structural engineering connections, specializing in bridge expansion joints, bearings, and seismic devices. Our portfolio includes significant projects such as providing joints for the HZM Bridge (the world’s highest-investment bridge), bearings for SOFI Stadium in Los Angeles (the world’s highest-investment building), and seismic devices for the Sichuan-Tibet High-Speed Railway (the world’s highest-investment railway). With over 150 patents, contributing 30% to our revenue, we demonstrate technical expertise through innovations like the world’s largest rubber bearings (2.5m x 2.5m), bearings with a capacity of up to 140MN, and joints capable of moving up to 1600mm. Our cross-disciplinary R&D team, consisting of over 30 professionals, including PhDs and Masters in mechanical engineering, materials science, IoT, and structural engineering, collaborates with leading research institutes and scientists globally. This approach has led to TWINSA, the world’s first structural load monitoring system, which represents a significant advancement in the field of structural health monitoring. Through in-situ calibration, TWINSA provides reliable internal force measurements, enabling automated early warnings, optimization of load distribution, and improved lifecycle management. We ensure that our products comply with international standards (EN, AASHTO), hold CE certifications, and feature a CNAS-accredited laboratory, recognized internationally through the ILAC Mutual Recognition Arrangement (MRA). With these efforts, we aim to transform structural engineering, making infrastructure smarter, more resilient, and sustainable for the future.
