Are You Making These Common Mistakes When Purchasing Cold Room Panels?

Overseas cold storage facilities operate under complex conditions; the specific environments-such as high humidity in Southeast Asia, salt spray in Latin America, and extreme heat in Africa-impose far stricter requirements regarding material quality, manufacturing processes, and regulatory compliance than domestic projects. Many overseas facilities suffer from issues like thermal leakage, rusting, high energy consumption, and failure to pass inspections; the root cause often lies in pitfalls encountered during the procurement phase, such as improper product selection or a blind focus on price comparisons.

This is the most common issue encountered in overseas procurement. When comparing prices, many overseas clients focus solely on the cost per square meter while overlooking critical panel specifications. Many low-cost manufacturers significantly misrepresent these parameters-such as supplying panels with actual thicknesses below the nominal 120mm or 150mm, using polyurethane cores that fail to meet density standards, or using thinner-than-specified steel facings.

Regional suitability challenges: In Southeast Asian countries like Indonesia, Thailand, and Vietnam, the climate is hot and humid year-round, while island projects in Latin America face heavy salt spray; panels with insufficient density or overly thin steel facings often suffer from moisture absorption, slight deformation, and cold air leakage at the joints within just six months of use. In high-temperature regions of Africa, inferior panels with compromised thermal insulation cause cold storage compressors to cycle on and off frequently, effectively doubling electricity costs.

Proper procurement standards: For export projects, prioritize verifying the panel core density, actual thickness, and steel galvanization specifications. Reject products with misrepresented data to avoid hidden costs associated with future repairs and increased energy consumption right from the source.

Assuming that "thicker panels are always better" or-to save money-using thin panels universally across all cold room structures can both lead to project inefficiencies and losses. Fresh-keeping rooms, low-temperature freezers, and blast freezers have vastly different requirements regarding panel thickness and thermal insulation performance; making a selection without considering these specific needs is counterproductive.

Regional suitability challenges: In the tropical climate of Southeast Asia, where ambient temperatures frequently exceed 30°C, a -18°C freezer requires PU panels at least 120mm thick (with 150mm recommended for blast freezers); using thinner 100mm panels would result in continuous thermal leakage and unstable internal temperatures. Conversely, for ambient-temperature fruit and vegetable storage in Africa, opting for 150mm panels would unnecessarily inflate procurement costs and waste resources.

Correct procurement standards: Panels should be precisely selected based on the type of stored goods, target storage temperature, and local ambient temperatures. Fresh-keeping rooms are best suited for 75–100mm panels, while freezers require 120–150mm panels, thereby striking the optimal balance between thermal insulation perfor  mance and cost-effectiveness.

Standard panels lack specialized protective treatments and are highly susceptible to damage in specific overseas environments.

Challenges regarding regional suitability: In rainforest-climate nations like Indonesia, Malaysia, and the Philippines, high humidity causes standard panel joints to suffer from condensation, water seepage, blistering, and mold growth. For coastal or island projects-such as those in Peru, Ecuador, or Suriname-severe salt-spray corrosion causes standard color-coated steel panels to rust and lose their finish within 1–2 years, compromising the structural seal. In African regions characterized by high temperatures and sandy, dusty conditions, panel surfaces are prone to abrasion and aging; inadequate protection accelerates equipment deterioration and failure.

Correct Procurement Standards: For coastal areas exposed to salt spray, specify thickened galvanized color-coated steel panels with anti-corrosion coatings; for high-humidity regions, specify PU core materials with a high closed-cell ratio combined with specialized sealing strips.

To shorten lead times, project managers may blindly opt for low-cost, generic panels that lack customization and after-sales service, ignoring specific project requirements and the challenges of overseas support. Given the long distances and extended logistics cycles involved in overseas projects, issues such as incorrect dimensions, quality defects, or subsequent damage incur exorbitant repair costs.

Challenges in regional adaptation: Facilities such as cold storage for island fisheries, small-scale food processing plants, and mobile cold storage units often require non-standard dimensions and specialized fabrication-areas where generic panels perform poorly. Furthermore, many manufacturers merely supply the materials without providing technical guidance; if assembly errors occur or panels are damaged, the lack of a support contact makes the project highly susceptible to abandonment or costly rework.
