Commercial Construction Projects High-rise Prefab Steel Structure Shopping Mall Building

Our shopping mall steel structure is a prefabricated high-rise, large-span building system specifically designed for commercial shopping malls, department stores, lifestyle centers, and other commercial complexes. This product uses high-quality Q355B/Q235B steel as the main load-bearing material, combined with standardized factory prefabrication and efficient on-site assembly, perfectly meeting the core requirements of commercial buildings for large open spaces, flexible layouts, stylish appearances, rapid construction, and safety and stability.

We provide one-stop customized services from architectural design, structural calculation, component processing, transportation, on-site installation to later maintenance. According to the customer's project land area, commercial positioning, investment budget and regional climate and geological conditions, we tailor the optimal steel structure scheme, draw construction drawings, and provide professional technical guidance and efficient construction services throughout the process to ensure the smooth implementation of the project.

• Main Steel Material: Q235B, Q355B high-quality H-section steel, box steel, I-beam and other profiles, with stable material and reliable toughness
• Surface Treatment: Sandblasting derusting + epoxy zinc-rich primer + intermediate paint + topcoat, or hot-dip galvanizing treatment, with strong anti-corrosion performance, and the service life of the steel structure can reach more than 50 years
• Span & Bay: Conventional single span 6-18m, multi-span combined design can be customized according to demand; column spacing is generally 6-12m, flexible adjustment according to space planning
• Seismic & Wind Resistance: Seismic fortification intensity up to 8-9 degrees, wind resistance grade up to 12 levels, snow load bearing can be customized according to regional climate characteristics
• Connection Mode: High-strength bolt connection, matched with a small number of factory welding, firm connection, high structural stability, convenient on-site assembly

1. Large Span & Flexible Space Layout: Reasonable large-span and bay design minimizes internal columns, creating a wide, barrier-free commercial space. It enables flexible shop division, atrium layout and scene creation, meeting diverse mall operation needs and facilitating future business adjustment.
2. Fast Construction & Shorten Project Cycle: Main steel components are factory-standardized with high precision. On-site bolted connection reduces wet operation and pollution, shortening the construction period by over 50% compared to concrete structures, helping developers put malls into operation earlier.
3. High Structural Strength & Superior Safety Performance: Made of high-strength low-alloy steel, the main frame has excellent bearing capacity, seismic, wind and snow load resistance. Designed in line with international standards, it ensures long-term safe operation of commercial buildings.
4. Light Weight & Lower Foundation Cost: Lightweight yet strong, it reduces building foundation load. For weak geological sites, it simplifies foundation treatment, cuts engineering costs and improves site adaptability.
5. Fashionable Appearance & Strong Decorative Compatibility: Highly plastic steel frame matches various exterior materials (glass curtain wall, aluminum composite panel, etc.), enabling personalized modeling, enhancing mall brand image and attracting passenger flow.

This product is suitable for various commercial construction projects, including large comprehensive shopping malls, urban commercial complexes, community lifestyle malls, commercial pedestrian street steel structures, multi-storey commercial stores and shopping mall expansion and renovation projects.
