Upgrading customization technology for light and heavy steel structures: BIM + intelligent construction, empowering high-quality customization

Technological innovation is the core competitiveness of steel structure customization. The application of technologies such as BIM and intelligent welding makes light and heavy steel customization more precise, efficient, and safe.

1. Application of core customization technology: BIM integrated design: achieving "the first mock examination" from design, production to installation data integration, optimizing component layout for lightweight steel structures, simulating lifting paths for heavy steel structures, reducing rework rate by 90%.

Intelligent production technology: Light steel adopts cold-formed automatic production lines, while heavy steel employs intelligent welding robots. This has increased the weld pass rate from 90% to 99.9%, and boosted production efficiency by 35%.

Innovative joint customization: Chongqing Iron & Steel adopts quick-assembly joints with column corner cast steel and beam end cover plates, which exhibit excellent seismic performance; light steel optimizes portal frame joints to achieve rapid bolt connection.

Green technology integration: Customized Building-integrated Photovoltaics (BIPV), with a 29% application ratio in newly built factories, yielding annual benefits exceeding 10,000 yuan, and a payback period of 5-8 years.

II. Customized Light and Heavy Steel Technology: For light steel structures, the focus is on breakthroughs in modular prefabrication technology, achieving a construction speed of "one floor in three days", while optimizing the integrated solution for corrosion prevention and thermal insulation.

Heavy steel structure: Focusing on preheating/post-heating technology for thick plate welding and structural health monitoring system, through real-time feedback of node stress from sensors, preventive maintenance is achieved.

III. Technical patents empower the customization process by enabling the application of specialized patents, such as "novel steel pipe column-beam connections" and "standardized components for steel frame structures", which address issues such as uneven stress distribution and complex components, thereby enhancing structural stability and cost-effectiveness.
