Product Description
Large-Span Industrial Steel Structures
High-strength steel structures manufactured to CE, ISO, and SGS standards for industrial facilities requiring large clear spans.
Product Overview
Large-span industrial plant steel structures are prefabricated building systems designed for high-strength, long-span industrial facilities. Utilizing standardized design, factory fabrication, and on-site assembly, these structures provide the most cost-effective and efficient solution for modern factories, warehouses, workshops, and logistics centers.
Structural Components
- Main Frame: H-beams and columns
- Secondary Structure: Purlins, wall beams, bracing system
- Enclosure: Roof/wall panels, insulation layer, skylights
- Accessories: Doors, windows, crane beams, ventilation system
Span Classification
Single-story industrial buildings with clear spans ≥30m and minimal central columns are classified as large-span steel structures:
- Medium to Large Spans (30–60m): Portal frames and ordinary steel trusses
- Large Spans (60–120m): Space trusses, space frames, and reticulated shells
- Extra-Large Spans (>120m): Prestressed steel structures, suspension cables, and tensioned beams
Typical column spacing ranges from 9–24m, suitable for heavy production, warehousing, logistics, aircraft hangars, and other applications requiring continuous large spaces.
