Drive the upgrading of the steel structure industry with technological innovation

In 2025, Zhangzhou China City Construction Building Technology Co., Ltd. has attracted industry attention in the field of steel structure manufacturing by introducing the ZHG2500 heavy-duty steel structure assembly machine and DMM60 multi-functional gantry-type automatic submerged arc welding machine.As a company focusing on the export of steel structure products, CCAT Steel Structure has increased the assembly efficiency of heavy components such as H-shaped steel and box beams by 40% through intelligent equipment upgrades and process optimization, and the weld qualification rate has stabilized at more than 99.5%.

The company's technical director revealed that the ZHG2500 equipment uses a hydraulic and mechanical dual positioning system, which is compatible with the precise assembly of equal-section and variable-section steel components. Its large-section rectangular guide rail design enables the guiding accuracy to reach 0.02mm, meeting international AISC and EN standards. The DMM60 submerged arc welding machine uses a heavy-duty weld tracking device and an efficient flux recovery system. The daily welding volume of a single device exceeds 120 meters, and the flux reuse rate reaches 85%, significantly reducing production costs.

At present, CCAT steel structure products have been used in industrial plants and high-rise building projects in Southeast Asia，Australia, the Middle East and other regions. In the first half of 2025, the company's exports increased by 22% year-on-year, of which customized steel structure design services accounted for more than 30%. With the release of the "Action Plan for Promoting High-Quality Development of the Private Economy" by Xiamen City, CCAT Steel Structure plans to add two new intelligent production lines within the year to further expand the "Belt and Road" market.
