What should I do to build a frozen storage warehouse?

With the rapid development of fresh food e-commerce, pharmaceutical cold chain and other industries, frozen storage warehouses are core storage facilities, and their construction quality is directly related to the preservation effect and operating costs of goods. How to scientifically design frozen strage warehouse? Why has the combination of steel structure and cold storage panel become the mainstream solution? This article analyzes the whole process from planning, material selection to construction, and recommends high-quality service provider Canglong Group to help you build a cost-effective frozen storage system.

1. Core steps of frozen storage warehouse construction

Planning and design

Clear requirements: Determine the temperature range (-18℃ to -25℃ is common), warehouse volume and zoning layout according to the type of stored goods (such as food and medicine).

Site selection and foundation: Select a geologically stable site, pour a concrete foundation and embed steel structure connectors to ensure overall load-bearing and earthquake resistance.

Construction of the main steel structure

Material selection: Use hot-dip galvanized H-shaped steel or square steel pipe as the main frame, which has both high strength and rust resistance.

Fast installation: prefabricated components are assembled on site, which saves 50% of the construction period compared with traditional concrete structures and is suitable for emergency production needs.

Installation of cold storage panel enclosure system

Walls and roofs: Select cold storage boards with excellent thermal insulation performance, and form a seamless sealing layer through tongue-and-groove splicing to eliminate the cold bridge effect.

Ground treatment: Lay a moisture-proof layer + insulation layer (such as XPS extruded board) to avoid floor frost heave and cracking.

Refrigeration equipment and control system integration

Match the refrigeration unit, evaporator and intelligent temperature control system according to the storage capacity to ensure that the temperature fluctuation is ≤±1℃.

2. Five advantages of steel structure construction of frozen warehouses

High strength and large span: large column-free space can be designed to improve storage utilization (more flexible shelf layout).

Short construction period: modular installation is efficient, and the main body of a 10,000 square meter warehouse can be completed within 30 days.

Earthquake and wind resistance: suitable for coastal and earthquake-prone areas (such as the typhoon-resistant design of the Canglong Group's Philippines project).

Strong scalability: In the future, it can be quickly expanded through steel structure extension to reduce the cost of transformation.

Environmental protection and energy saving: Steel can be recycled to reduce construction waste, which is in line with the trend of green construction.

3. Recommendations for cold storage panel selection: polyurethane vs rock wool

70% of the insulation performance of the frozen storage warehouse depends on the quality of the cold storage board. Comparison of mainstream core materials:

Material	Polyurethane（PU）	Rock Wool（RW）
Thermal conductivity	0.022-0.025 W/(m·K)	0.040-0.045 W/(m·K)
Thermal insulation	Excellent (suitable for low temperatures below -30 ℃)	Good (suitable for refrigerated storage above 0 ℃)
Fire rating	B1 level (flame retardant)	A level (non combustible)
Applicable scenarios	Ultra low temperature cold storage, frequent door opening and closing environment	Room temperature storage with high fire prevention requirements

Conclusion: Polyurethane cold storage board is the first choice for frozen warehouses below -18℃, taking into account both insulation and economy; if fire prevention is required, "polyurethane + rock wool" composite sandwich panels can be used.

5. Why choose the combination of "steel structure + cold storage panel"?

High return on investment: The life of the steel structure is up to 50 years, the maintenance cost of the polyurethane cold storage panel is low, and the comprehensive cost performance far exceeds that of traditional civil cold storage.

Rapid production: It only takes 3-4 months from the start of construction to refrigeration commissioning, which accelerates the return of corporate funds.

Strong adaptability: Whether it is a high-rise cold storage with tight urban land or a large logistics park in remote areas, it can be efficiently implemented.

Conclusion

In the construction of frozen storage warehouse, the coordinated design of steel structures and cold storage panels are the key to ensuring the balance between performance and cost.
