Canglong Steel Structure assists the crane factory building project in Thailand

Canglong Steel Structure is a carefully crafted crane factory project for Thai clients, focusing on professional steel structure design and adaptability to heavy industrial loads, showcasing innovative practices in the industrial construction field in Southeast Asia. The project adopts a modular steel structure system, and the main frame uses Q355B high-strength H-beam (specification H500 × 200 × 10 × 16) as the columns and main beams. By optimizing the design of the crane beam through finite element analysis, a customized double web box girder structure is designed specifically for the 32/5-ton bridge crane. After calculation, it can withstand a maximum wheel load of 285kN and a dynamic load factor of 1.4, fully meeting the requirements of ISO 8686-1 standard. Combined with C200 × 75 × 20 × 2.5 cold-formed C-shaped steel purlins and Z-shaped steel wind resistant support systems, a high rigidity spatial grid is formed, and the overall seismic performance of the structure meets the Level 4 standard of Thai Building Code TIS 475-2551.

The innovative integration of the enclosure system includes a 150 × 150 × 6mm square tube secondary beam frame, paired with a 0.5mm thick PVDF coated profiled steel plate wall. The unique sliding node design can relieve thermal expansion and contraction stress. The roof system adopts two-way 2% drainage slope design, and DN150 UPVC siphon drainage pipe cooperates with gutter system to achieve the drainage capacity of 120 mm/h rainstorm intensity. Industrial grade aluminum alloy wind resistant doors and windows (with air tightness up to ASTM E283 Class 40) are precisely integrated with steel structures, and BIM deepening design achieves a prefabrication rate of 92% for components. On site, high-strength bolt connection (10.9S M24) technology was used, and 100% ultrasonic testing was conducted on key welds, providing a heavy-duty industrial plant solution with full lifecycle cost optimization for Thai customers.
