High-Speed Modular Construction: Pre-Engineered H-Section Steel Framing System for Industrial Facilities

As an innovative solution in modern construction, prefabricated steel structure factories have gained significant popularity due to their cost-effectiveness, logistical efficiency, and rapid installation advantages. This structural system demonstrates notable superiority over traditional concrete construction methods through its optimized engineering design and industrialized production approach.

Structurally, these facilities are systematically composed of standardized components including:

1. Primary load-bearing elements: H-shaped steel columns and beams
2. Secondary framing: Purlin systems
3. Enclosure components: Corrugated roof sheeting/wall panels (available in single-layer steel sheets or insulated sandwich panels)
4. Functional accessories: Roll-up doors and ventilation windows

The structural assembly employs differentiated connection methodologies:
• High-strength bolts (Grade 10.9S) for primary member connections (column-beam joints)
• 4.8S grade bolts for purlin-to-mainframe attachments
This modular connection system enables erection speeds 60-70% faster than conventional cast-in-place concrete structures, significantly reducing construction timelines.

The envelope system utilizes lightweight steel cladding materials (typically 0.4-0.8mm gauge) with the following advantages:
• 70-80% weight reduction compared to concrete roofs
• Weather-resistant zinc-aluminum-magnesium coatings (AZ150 grade)
• Optional thermal insulation through polyurethane/PIR sandwich panels (U-value: 0.22-0.28 W/m²·K)
• Installation rates exceeding 500m²/day per crew
