The high-strength prefabricated steel structure warehouse offers a complete solution with fast delivery and professional installation guidance. The structure combines a durable internal steel frame with a protective external enclosure system for long service life.

The frame adopts a portal steel structure consisting of columns, beams, and bracing. Together with the enclosure, it forms a fully sealed building capable of withstanding strong winds, heavy rain, and snow loads.

All metal components are cut, welded, drilled, and painted in our workshop before being delivered to the construction site. Each part is connected with high-strength bolts, enabling quick and efficient installation while reducing labor costs.

• Tension members
• Compression members
• Bending members
• Combined-stress members
• Connections

Multi-story steel structure buildings are high-rise or mid-rise structures (typically 3-20+ floors) using steel as the primary structural framework. They combine strength, efficiency, and design flexibility, making them a popular choice for diverse urban and commercial needs.

• High Strength-to-Weight Ratio: Steel's strength allows for lighter yet robust frameworks, reducing foundation loads while supporting multiple floors and heavy usage.
• Design Flexibility: Steel's adaptability enables open floor plans, large spans, and creative architectural features, maximizing usable space and aesthetic appeal.
• Rapid Construction: Prefabricated steel components are manufactured off-site and assembled quickly, shortening build times by 20-40% compared to concrete structures.
• Durability & Resilience: With proper corrosion protection, steel resists environmental wear, fire (when fireproofed), and seismic activity, ensuring a long lifespan (50+ years).
• Sustainability: Steel is 100% recyclable, and its lightweight nature reduces material waste. It also supports energy-efficient upgrades.

• Commercial Buildings: Offices, shopping malls, and hotels (benefiting from open layouts and quick occupancy)
• Residential Complexes: Apartments or mixed-use buildings (balancing space efficiency and structural stability)
• Institutional Facilities: Hospitals, schools, and government buildings (prioritizing safety and adaptability for evolving needs)

We implement rigorous quality control measures throughout the project lifecycle, including:

• Material inspections before and after fabrication
• Precision measuring, cutting, and welding
• Accurate hole and cleat placement
• Proper packaging and loading sequence
• On-site erection when required
