The 8th China (Shanghai) International Technology Fair, co-hosted by the Ministry of Commerce, Ministry of Science and Technology, National Intellectual Property Administration, and Shanghai Municipal People's Government, was held from April 15-17, 2021, at the Shanghai World Expo Exhibition and Convention Center.

OPEN Steel Structure was invited to participate in the "Technology Innovation Special Session" at the China (Shanghai) International Technology Fair. Chairman Chen Ming introduced the technical advantages, manufacturing processes, and application cases of the "Corrugated Steel Plate Composite Frame System" developed by OPEN.

In response to current trends, OPEN has introduced the CS-Frame technology, which allows for better integration of steel and concrete. This system eliminates the need for formwork and scaffolding and replaces traditional reinforcement, making it an economical and efficient new frame structure.
