A Multi-story Modular Steel Structure Office Building is a scalable, high-efficiency building solution engineered for medium-rise workspace needs (2-6 stories), integrating modular steel framing, vertical load-bearing capacity, and architectural versatility. Manufactured with Q460/Q690 ultra-high-strength steel (main frames, columns, floor beams) and 12.9-grade high-strength bolts, this product features stacked modular units (standard size: 3m×6m, 3m×8m) with rigid vertical connections and horizontal bracing, ensuring structural stability (wind load resistance ≥1.0kN/m², seismic intensity ≤8 degrees) and vertical load-bearing capacity ≥5kN/m². The steel frame adopts a dual-core design (modular columns + floor trusses) with yield strength ≥460MPa, optimized for lateral stiffness (inter-story drift ≤1/500) and load distribution, while factory prefabrication rate ≥95% reduces on-site construction time by 70% compared to traditional concrete buildings. Key features include integrated floor systems (steel deck + concrete slab, fire resistance ≥2 hours), exterior wall systems (aluminum alloy curtain wall or color steel sandwich panels with thermal insulation), and pre-installed vertical systems (elevators, stairs, plumbing risers). The building supports customized floor plans (open-plan offices, private offices, meeting rooms, rest areas) and architectural designs (glass facades, exterior cladding customization), with thermal insulation U-value ≤0.4W/(m²·K) and sound insulation ≥45dB. The steel frame surface is treated with cathodic electrophoresis + fluorocarbon coating, providing salt spray resistance ≥1500 hours and adapting to urban commercial areas, industrial parks, and suburban developments. It complies with GB 50017-2017, GB 50011, and AISC 360 standards, supporting building height up to 24m (6 stories) and total floor area up to 5000m². Professional services include structural load calculation, BIM-based modular design, wind tunnel testing, on-site installation supervision, and post-construction acceptance.

Multi-story Modular Steel Structure Office Buildings are efficient, scalable solutions for medium-rise workspace demand, widely used in commercial and industrial developments. Certified by GB 50017-2017, GB 50011, and ISO 9001, they meet strict high-rise structural standards. Typical applications include urban commercial office buildings (2-4 stories), industrial park comprehensive office buildings, science and technology park R&D centers, modular office complexes, and campus office buildings. They are particularly suitable for projects with tight construction schedules (e.g., new industrial park development), limited construction space (urban core areas), or phased expansion (e.g., office building capacity increase). The modular design also allows for flexible floor plan adjustments and future expansion by adding additional modules. The minimum order quantity is 1 building (customized per project), with full tailoring based on floor number, total area, layout, and architectural design. Competitive project-based pricing and flexible delivery terms (30-60 workdays) support medium-rise construction schedules, while a monthly supply capacity of 30 building sets (modules combined) ensures timely delivery. Customization options include corrosion-resistant upgrades (super duplex stainless steel components), high-end exterior finishes (glass curtain wall, stone cladding), fire-resistant coating (≥2.5 hours), and intelligent building integration (smart lighting, HVAC control systems).
