The steel structure industry is widely used in: Industrial plants and warehousing logistics buildings; Truss bridges and municipal structures; Rail transit and transportation hubs; Automated parking garages and steel platforms; Photovoltaic supports and new energy structures; Towers, masts, and tubular truss structures; High-rise building steel structures.
The industry as a whole exhibits the following characteristics: Many large components and long weld lengths; Significant differences in component specifications and a high proportion of non-standard parts; Uneven production batches (project-based); Long processing chains and high collaboration costs; High requirements for welding quality and structural strength.
Against the backdrop of intensifying competition in engineering projects and rising labor costs, the industry is upgrading from: Traditional "manual cutting + grinding + manual welding" to "laser processing + automated welding + intelligent flexible manufacturing".
Industry Challenges
01
High proportion of manual welding, resulting in inconsistent quality
Large welds requiring prolonged welding → prone to fatigue Quality depends on individual experience High rework and secondary grinding rates Difficult to meet quality traceability requirements for large-scale projects
02
Traditional cutting and material preparation methods, limiting efficiency and precision
Diversified engineering orders, insufficient flexible production capacity
Large differences in component dimensions Variable batch quantities
04
Increased strength and corrosion resistance requirements, leading to greater pressure on surface treatment
Insufficient pre-welding surface cleaning Paint/rust residue affects welding quality Manual cleaning generates significant dust and creates a poor working environment
05
High process adjustment costs Low equipment utilization
Frequent switching of production tasks
06
Enhanced environmental protection and safety
Environmental protection will serve as a core value to attract more outstanding cooperative projects.
