High-efficiency prefabricated structures designed to combat extreme ambient heat and maintain strict thermal parameters.
As the primary economic powerhouse of Thailand, Bangkok represents the central hub for the food, pharmaceutical, and logistics sectors within Southeast Asia. The demand for robust cold storage warehouse buildings has grown exponentially over the past decade. Driven by government investments in the Eastern Economic Corridor (EEC), the expansion of modern trade supermarkets, and the massive growth of food processing industries for export (such as seafood and tropical fruits like durian and mangosteen), high-performance cold storage facilities are essential infrastructure.
However, engineering a cold storage facility in Bangkok presents distinct geographical and climatic challenges. Bangkok is characterized by a high-humidity tropical climate with average temperatures consistently exceeding 32°C, and frequent heavy rainfall during the monsoon season. Additionally, the soft clay soils of the Bangkok Plain require sophisticated foundation engineering to prevent structural settling. Standard warehouse specifications are insufficient; builders must prioritize moisture barriers, heavy-duty anti-corrosive structural steel coatings, and thermal insulation panels that completely eliminate thermal bridging.
The blueprint for high-efficiency, multi-temperature cold storage facilities engineered for longevity.
Our structural design leverages high-tensile Q355B structural steel, processed under strict ISO 9001 factory controls. Columns and trusses are shot-blasted to Sa 2.5 standard and protected with hot-dip galvanization or multi-layer epoxy coating systems. This guarantees protection against corrosion in coastal and industrial areas surrounding Bangkok, such as Samut Prakan and Chonburi.
We utilize PIR/PU sandwich panels with a density range of 40-42 kg/m³. Panels feature cam-lock joints and double-tongue-and-groove configurations to ensure airtightness. Panel thicknesses are engineered based on internal design temperatures:
To prevent sub-floor freezing, which causes soil expansion and structural floor cracking, we integrate under-floor ventilation piping or electric heating matrices, topped with high-load extruded polystyrene (XPS) insulation boards and reinforced finished concrete slabs designed to support heavy forklifts and racking loads.
With Thailand's abundant sunshine, cold storage roofs are optimized with reinforced structures to accommodate solar photovoltaic panels. Integrating solar power can offset daytime cooling energy demands by up to 40%, boosting operational profitability.
Specialized PVC or synthetic composite insulating spacers inserted at steel connection points to completely isolate the cold envelope from external hot structural steel elements, preventing condensation and energy leaks.
Inner steel faces of panels are coated with a cleanable, non-toxic, anti-microbial paint layer compliant with global food hygiene requirements, ensuring clean environment operations.
Highly adaptable prefabricated modules optimized for urban sites and sustainable off-grid agricultural setups.

The company remains dedicated to providing innovative steel warehouse solutions that create lasting value for global customers.
Purchasing a prefabricated cold storage warehouse from China and assembling it in the Bangkok Metropolitan Area requires adhering to specific administrative processes and technical compliance. Metro Build supports developers and general contractors with complete engineering documentation to streamline local approvals.
All prefabricated structural steel systems shipped to Thailand are calculated and detailed in compliance with the local Department of Public Works and Town & Country Planning (DPT) guidelines. We run seismic simulations and structural wind load calculations (up to 120 km/h for the central plains) to guarantee structural safety under extreme weather conditions.
Through the China-ASEAN Free Trade Agreement, import duties on prefabricated steel structures and panels can be significantly reduced or completely exempted (0% import tariff) when importing to Thailand. Dongguan Metro Build provides fully compliant Form E documentation, enabling buyers to reduce clear-cut landing costs at Bangkok Port (Klong Toey) or Laem Chabang Port.
For agricultural, seafood, and food processing plants, our prefabricated components match the strict certification requirements of the Thai Food and Drug Administration (FDA) and international HACCP/GMP inspections. Seamless joints, antimicrobial panels, flush-mount wall-to-floor covings, and rapid-rise insulated roller doors ensure thermal environment hygiene.

In response to global carbon neutrality initiatives and the rising operational costs of traditional warehouses, Metro Build is continuously implementing and refining its technolgical roadmap. This design philosophy focuses on maximizing efficiency, durability, and automation.
While standard EPS and PU panels remain cost-effective options, our modern design standard leans heavily toward Polyisocyanurate (PIR) and phenolic core panels. PIR delivers superior fire performance (Class B-s1, d0 under EN 13501-1) and has a lower thermal conductivity rating (0.020 W/m·K) compared to polyurethane, which saves energy in the long term.
Modern Bangkok warehouse facilities are moving toward smart operations. By integrating IoT sensors directly within panel interfaces and structural nodes, operators can continuously monitor temperature gradients, localized humidity, frame stress, and door seal states from a central dashboard, enabling preventative maintenance and preventing stock damage.
All framing, purlins, structural joints, and insulation panels are pre-engineered, CNC-cut, and pre-drilled at our advanced factory in Dongguan. When shipped to the site in Bangkok, assembly functions like a precise modular puzzle. This minimizes site cutting, eliminates hot welding, reduces labor requirements by 40%, and reduces construction timelines by weeks compared to traditional building practices.
Technical answers to help developers design and import cold storage structures to Thailand.
PIR (Polyisocyanurate) panels offer superior thermal resistance (R-value) and significantly higher fire rating protection compared to EPS and traditional PU. In Thailand, where daytime temperatures frequently exceed 35°C, PIR panels minimize energy loss through the wall envelope. Furthermore, many Thai insurers provide lower premium rates for cold warehouses built with fire-rated PIR cores.
We work in tandem with local Thai structural engineers. Our prefabricated steel frame warehouses are engineered using high-tensile steel, which features a high strength-to-weight ratio. This reduces the total dead load of the superstructure by up to 35% compared to concrete construction, minimizing the size, depth, and cost of concrete piling works required to support the building on soft Bangkok clay.
Yes. Under the China-ASEAN Free Trade Agreement (ACFTA), you can apply for zero-tariff import duties on prefabricated steel components by using a Form E Certificate of Origin. Dongguan Metro Build provides all the necessary certifications and custom clearing documentation to ensure smooth import clearance through Bangkok Port or Laem Chabang Port.
For freezer applications (below 0°C), we design a multi-layer insulated floor system. Below the concrete slab, we install a high-density XPS moisture barrier, followed by a network of ventilation pipes (natural or forced air) or sub-floor heating mats. This prevents moisture from accumulating and freezing in the soil, which otherwise causes frost-heaving and structural floor failures.
Our standard designs for the Bangkok and surrounding coastal plains are engineered to withstand wind speeds of 100 to 120 km/h, complying with Thailand's Department of Public Works and Town & Country Planning (DPT) structural codes. Ratings can be customized for coastal zones requiring higher wind-load standards (up to 150 km/h).
