Cold Storage Steel Building

Cold Storage Steel Building is a prefabricated steel structure designed for temperature-controlled storage facilities. It is commonly used for frozen food storage, fresh produce preservation, meat and seafood storage, pharmaceutical warehousing, beverage storage, logistics distribution centers, and refrigerated processing spaces.

This specification is for reference-the final implementation can be adjusted according to project-specific requirements.

Main Structural System

• Portal frame, rigid frame, bent frame, or truss structure designed according to building span and load requirements, providing stable load-bearing performance and efficient space utilization.
• Q235B, Q345B, or Q355B steel materials selected according to structural requirements and project specifications.
• H-section steel, square tube, channel steel, angle steel, and C-section steel components provide structural strength and fabrication flexibility.
• High-strength bolt connection, welding, or combined connection systems can be adjusted according to installation and engineering requirements.

Secondary Structural System

• C/Z section purlins, bracing systems, tie bars, and support members improve structural stability and distribute loads effectively.

Roof & Wall Cladding System

• Color steel sheets or insulated sandwich panels provide enclosure performance and thermal insulation.
• Roof lighting belts, skylights, and sidewall daylight systems increase natural lighting and reduce daytime power consumption.
• Roof ventilation skylights support internal airflow management.

• Dimensions: customized length, width, height, span, single-span or multi-span configurations.
• Colors: customized roof, wall, and structural coating colors.
• Insulation Thickness: multiple sandwich panel thickness options according to temperature requirements.
• Roof Types: single-slope, double-slope, curved roof, and other project-specific configurations.
• Doors and Windows: optional rolling doors, sliding doors, swing doors, skylights, louvers, and ventilation systems.
• Load Requirements: customized wind loads, snow loads, seismic grade, and local code requirements.
• Surface Treatment: hot-dip galvanizing, sandblasting, shot blasting, anti-corrosion coatings, and fire protection systems.
• Fire Protection: optional thin-layer or thick-layer fire-retardant coatings and fireproof boards.

Custom solutions are developed according to project requirements and local building regulations.

Cold Storage Steel Building vs Cold Storage Concrete Building

• Raw material inspection: verification of steel grade, material certificates, dimensions, and chemical composition according to applicable standards.
• Cutting and fabrication inspection: monitoring of dimensional tolerances, hole positioning accuracy, and assembly consistency.
• Welding inspection: visual inspection (VT), ultrasonic testing (UT), and magnetic particle testing (MT) where applicable.
• Surface treatment inspection: measurement of galvanizing thickness, coating adhesion, and surface uniformity.
• Bolt and connection inspection: testing of high-strength bolt performance and connection accuracy.
• Pre-delivery dimensional inspection: checking member dimensions, fabrication tolerances, and assembly fit-up.
• Third-party inspection available: SGS inspection services can be arranged according to project requirements.
• Manufacturing management system: production carried out under ISO quality management systems; materials and testing can comply with CE and ASTM requirements when specified by project standards.

• Steel components are bundled according to component type and identification marks for easier unloading and site installation.
• Small accessories and fasteners are packed in labeled cartons or steel boxes with packing lists.
• Roof and wall panels are stacked with protective separation layers to reduce surface damage during transport.
• Container loading plans are arranged according to component dimensions to improve container utilization.
• 40HQ or open-top containers can be selected depending on structure size and project requirements.
• Shipping documentation can include packing lists, material certificates, inspection reports, and installation drawings.
• Typical production lead time: approximately 20–45 days, depending on project quantity, specifications, and customization requirements.
