Steel Structure Cold Storage

A steel structure cold storage is a warehouse or facility built with a steel frame, designed specifically for storing perishable goods at controlled low temperatures. These structures are widely used in the food, pharmaceutical, and chemical industries to preserve products that require refrigeration or freezing.

Structural Strength And Durability
Uses high-strength steel to provide excellent load-bearing capacity and impact resistance.
Designed to have a long life, typically over 50 years metal storage building, and to withstand harsh weather and environmental impacts.

Construction Efficiency
Prefabricated components enable fast on-site construction and shorten the construction period.
The simple assembly process reduces on-site labor requirements and construction costs.

Design Flexibility
Designs can be customized according to customer needs, including size, shape and internal layout.
It has strong adaptability and is suitable for the construction of cold storage of various sizes and functions.

Thermal Insulation And Energy Saving
Use efficient insulation materials to reduce energy consumption in cold metal sheds storage.
Modern HVAC systems help maintain stable temperatures while reducing energy consumption.

Economical
The material cost and construction cost are relatively low, and the economic benefits are significant.
Fast construction cycles mean faster return on investment.

Steel Structure Cold Storage Design

01 Site Planning and Layout
Location: Ensure good accessibility for transportationand proximity to supply chains. Evaluate soil conditions for load-bearing capacity.
Orientation: Position the structure to minimize sunexposure and heat gain. Consider wind direction to aid natural cooling if possible.

02 Structural Framework Design
Steel Frame: Use a steel framework with columns,beams, rafters, and purlins. Steel grades should bechosen based on load requirements and local climate conditions.
Foundation: Design a foundation capable of supporting heavy steel structures and cold steel frame storage building units. Insulatedfoundations are recommended to prevent heat transfer from the ground.

03 Insulated Panels And Cladding
Insulated Sandwich Panels: Use prefabricated panelswith polyurethane (PU) or polystyrene (EPS) cores forwalls, ceilings, and doors. These panels offer highthermal insulation and low thermal conductivity.

Panel Thickness: Choose panel thickness based on temperature requirements:
0°C to +10°C (Chilled Storage): 100mm to 150mm panel thickness.
-10°C to -30°C (Freezing Storage): 150mm to 200mm panel thickness.
Wall and Roof Cladding: Use durable, corrosion-resistantcladding for external walls and roofing. Color-coatedsteel sheets are common choices.

04 Thermal And Air-tightness Design
Sealing: Ensure airtight sealing of panels, door frames, and joints to prevent air leakage.
Doors: Install insulated, high-speed roll-up doors orsliding doors. Equip them with air curtains or dock sealsto maintain internal temperatures during entry and exit.
Cold Bridge Prevention: Implement measures to preventheat transfer at joints and fasteners, which can lead to condensation or ice formation.

05 Floor Design And Insulation
Insulated Flooring: Design floors with multi-layerinsulation to avoid heat transfer from the ground andprevent frost heave.

A typical design might include:
Insulation Layers: Rigid foam insulation panels.
Concrete Slab: Reinforced concrete for load-bearingcapacity.
Anti-Slip Finish: Epoxy coating to prevent slipping in icy conditions.
Heating System: Consider underfloor heating if frostheave is a concern in freezing temperatures.

06 Refrigeration And HVAC Systems
Refrigeration Units: Choose energy-efficient andenvironmentally friendly refrigeration units based on therequired cooling load and storage volume. Consider splitsystems, modular refrigeration, or centralized systemsdepending on the facility size.
Evaporators and Condensers: Select evaporators withdehumidification capabilities to control humidity inside the cold steel frame storage shed.
Temperature Zones: Design separate compartmentswith independent temperature controls for differentproduct requirements (e.g., frozen section, chilledsection).
Air Circulation: Implement proper air circulation for eventemperature distribution to prevent hot/cold spots within the facility.

07 Energy Efficiency And Sustainability
LED Lighting: Install energy-efficient LED lights that emitlow heat, with sensors for occupancy detection.
Solar Panels: Where feasible, incorporate solar panels onthe roof to power refrigeration units and lighting,reducing operational costs.
Heat Recovery System: Use heat recovery systems fromrefrigeration units to optimize energy usage for heating and defrosting.

08 Internal Layout And Space Planning
Racking and Storage: Plan the warehouse steel structure storage layout withspace-saving racking systems based on the types ofgoods stored. High-density storage racks or automatedstorage and retrieval systems (ASRS) can maximize theuse of vertical space.
Loading and Unloading Areas: Design loading dockswith insulated dock shelters or dock seals to minimize cold air loss.
Safety Zones and Accessibility: Include clear pathwaysfor material handling equipment and emergency exits.

09 Safety And Compliance
Fire Safety: Install fire suppression systems suitable for cold environments, such as dry-pipe sprinkler systems.
Compliance with Regulations: Ensure compliance withlocal and international standards for cold storage, such as FDA, ISO, or HACCP guidelines for food storage.
