Large-Span Single-Story Steel Structure Cold Storage

HCGG delivered a flagship single-story maximum-height & maximum-span steel structure cold storage project, setting a new benchmark for large-scale cold chain infrastructure.

Floor Area:

16,567 m²

Steel Consumption:

1,500 tons

Structure Type:

Single-story steel structure

Key Dimensions:

42 m (height) * 47 m (max span)

Core Advantage: Column-free interior, ultra-large space for high-efficiency cargo storage & logistics

1. Heavy-Duty Steel Frame System

   Adopts high-strength H-section steel columns & beams as the main load-bearing structure, ensuring exceptional stability, seismic resistance & durability under extreme height and large-span conditions. The 47 m clear span design eliminates intermediate columns, maximizing usable space and enabling flexible layout of racking and handling equipment.

2. High-Efficiency Insulation & Envelope

   The enclosure system uses premium polyurethane (PU) sandwich panels with low thermal conductivity (0.022 W/m·K), delivering superior thermal insulation, moisture resistance and airtightness. This effectively minimizes cooling loss, maintains precise temperature control (-25°C to 15°C), and reduces long-term energy costs.

3. Optimized Structural Design

   • Height: 42 m single-story height meets high-bay storage and automated logistics requirements.
   • Steel Efficiency: 1,500 tons of steel for 16,567 m² area balances structural safety and cost-effectiveness.
   • Modular Construction: Factory prefabricated components ensure fast on-site assembly, shortening construction period and reducing on-site risks.

• Unmatched Space Utilization: The 47 m span * 42 m height column-free space enables high-density storage and seamless operation of large machinery, ideal for bulk goods, food processing and distribution centers.
• Reliable Performance: Engineered for harsh environments, the steel structure resists corrosion, deformation and extreme weather, ensuring 24/7 stable operation of the cold storage.
• Cost-Effective Solution: Integrates structural design, material manufacturing and construction supervision, providing a one-stop solution that saves time and costs for clients.

This large-span single-story steel structure cold storage project fully demonstrates HCGG’s strong technical strength and rich experience in heavy-duty cold chain construction. It is an ideal choice for clients seeking large space, high efficiency and long-term reliability in cold storage facilities.
