The production and manufacturing process of Canglong steel structure
As a leading supplier of steel structure building solutions in China, Canglong Group has built an intelligent manufacturing system covering the entire process of design, processing, and testing, relying on modern production bases and advanced technology. Its production strength is reflected in the following core aspects:
1. Digital design and precise planning
Canglong Group adopts BIM technology for 3D modeling and detailed design, combined with AI algorithms to optimize material utilization, ensuring that the dimensional accuracy error of components is controlled within ± 1mm. The design team uses simulation technology to rehearse the construction process, avoiding potential problems in advance and significantly shortening the project cycle.
2. High end equipment clusters and precision machining
Cutting process: Equipped with German imported plasma cutting machine and laser cutting machine, it can achieve high-speed precision cutting of steel with a thickness of 0.5mm to 100mm, and the perpendicularity error of the incision is less than 0.5%.
Forming and Welding: Fourteen automated welding production lines are equipped with robot welding systems, supporting processes such as submerged arc welding and gas shielded welding, with a weld seam inspection pass rate of 99.2%. The 5000 ton CNC hydraulic press can complete the cold bending forming of complex curved components with an accuracy controlled within ± 0.3mm.
Surface treatment: Using fully automatic shot blasting rust removal line and electrostatic powder spraying line, combined with hot-dip galvanizing process, the coating adhesion meets ISO 2063 standard, and the salt spray test life exceeds 2000 hours.
3. Whole process quality control system
Material traceability: The steel is purchased from leading domestic enterprises such as Baosteel and Ansteel, and each batch of raw materials is analyzed by spectrometer composition and ultrasonic testing.
Process standardization: Implementing the ISO 9001 international quality management system, key processes such as welding parameters and coating thickness are monitored in real-time through the MES system.
Finished product testing: Equipped with a three-dimensional coordinate measuring instrument and stress detector, 100% testing is conducted on the bearing capacity, deformation and other indicators of the components to ensure compliance with the requirements of GB 50017 standard.
4. Large scale production capacity and flexible production
Relying on a production base of 250000 square meters and an intelligent factory building of 58000 square meters, Canglong Group has an annual production capacity of 50000 tons, covering a full range of components such as H-beams, box columns, and spatial trusses. Its flexible production line supports multi model mixed flow production, and through AGV logistics system and digital twin technology, achieves a 30% reduction in order delivery cycle.
5. Green Manufacturing and Sustainable Development
The group has introduced a circular economy model, with a steel scrap recovery rate of 95% and a welding dust purification rate exceeding 99%. The painting workshop adopts water-based environmentally friendly coatings and waste heat recovery systems, reducing energy consumption per unit output value by 25% compared to industry standards, and has been awarded the title of “National Green Factory”.
