We provide full custom design, manufacturing, and global delivery for portal frame steel workshops:
Overview Portal Frame Steel Structure Workshop is a prefabricated, clear-span industrial building system designed for factories, warehouses, production plants, logistics centers, and workshops. Engineered with high-strength H-section steel beams and columns, it offers superior structural stability, large clear spans, fast assembly, and full customization to meet your operational needs.
Key Features & Advantages
Large Clear Span & Open Space • Clear span up to 30m+ without internal columns • Maximum usable floor area for machinery, production lines, and storage • Ideal for heavy equipment, overhead cranes, and flexible layout
High Strength & Structural Stability • Main frame: Q235 / Q355 grade H-beam steel • Wind resistance: up to 120km/h (customizable for typhoon zones) • Snow load: 0.3–1.5kN/m² (adjustable per region) • Seismic resistance: Grade 8–9 • Service life: 50+ years with proper maintenance
Fast Construction & Cost Efficiency • All components prefabricated in factory with precision cutting & welding • On-site bolt-on assembly — no on-site welding required • Construction time 30–50% faster than concrete buildings • Lower foundation cost due to light weight • Reduced labor & overall project cost
Durable & Low Maintenance • Hot-dip galvanized or epoxy paint anti-corrosion treatment • Weather, rust, fire, and pest resistant • Minimal long-term maintenance
Eco-Friendly & Recyclable • 100% recyclable steel materials • Low construction waste & pollution • Energy-efficient insulation options available
Full Customization • Custom width, length, eave height, roof shape • Optional mezzanines, cranes, skylights, ventilation, insulation • Flexible door/window placement & size
