South America is the golden zone of global agriculture. Brazil’s soybeans and beef, Argentina’s grains and oil, Chile’s grapes and cherries, Colombia’s coffee and flowers together constitute the core supply system of global food and cash crops.
However, the demand for storage, sorting and transportation of massive agricultural products in the process of agricultural modernization has formed a sharp contradiction with the backward storage facilities in some parts of South America. Traditional wooden warehouses are susceptible to insect infestation, dampness and rot. Simple sheds cannot meet the requirements of temperature control and moisture resistance. Temporary storage has a higher loss rate due to its short life and poor safety (according to FAO statistics, the post-production loss rate of agricultural products in South America is as high as 15%-20%, far exceeding the global average of 10%).
In this context, metal office warehouse buildings are becoming a key infrastructure for the upgrading of South American agriculture with their high strength, weather resistance, modularity and other characteristics. This article analyzes the adaptation logic of metal warehouse buildings based on the differences in agricultural demand in Brazil, Argentina, Chile, Colombia and other countries, and shows how Canglong Group can solve the difficulties of agricultural storage with prefabricated and customized solutions through practical cases in South America.
1. South American agricultural demand map
South American agriculture is characterized by a large latitude span, diverse crop types, and distinct industrial chain stages. The core demands of different countries can be summarized into three categories:
1.1 Brazil: Large-scale storage and mechanized operation requirements in major soybean/corn producing areas
Brazil is the world’s largest soybean exporter (103 million tons of exports in 2023), and the main producing areas such as Mato Grosso and Parana are dominated by large farms (with an average planting area of more than 5,000 hectares). Its storage needs focus on:
Large-capacity storage: The capacity of a single warehouse needs to match the batch operation of a combine harvester (the daily harvesting volume can reach 500 tons), requiring a warehouse span of ≥30 meters and a stack height of ≥6 meters.
Fast turnover: Soybeans need to be dried, graded, and loaded within the harvest season (2-3 months), and the warehouse needs to be equipped with a loading and unloading platform (width ≥ 6 meters) and a lifting cargo elevator (load ≥ 5 tons).
Moisture and mildew proof: The tropical savanna climate (humidity > 80% in the rainy season) is prone to condensation on grains. Warehouses need to strengthen roof insulation (sandwich panel core material thermal conductivity ≤ 0.04W/(m·K)) and ground moisture proofing (concrete base + waterproof membrane).
1.2 Argentina: Cold chain integration and multi-category compatibility requirements for mixed beef/wheat agriculture
Argentina is the world’s third largest beef exporter (export volume 850,000 tons in 2023) and a major wheat producing area in the world (the main producing area is the Pampas). Its storage demand presents the dual-track characteristics of “fresh food + dry goods”:
Cold chain storage: Beef needs to enter the 0-4℃ cold storage within 48 hours after slaughter, and the warehouse needs to be equipped with polyurethane insulation board (thickness ≥150mm), refrigeration unit (cooling capacity ≥50kW) and ventilation system (air exchange frequency ≥12 times/hour).
Multi-category compatibility: Dry goods such as wheat and corn need to be stored separately from meat, requiring modular warehouse design (flexibly divided into refrigerated area and dry goods area), and reserved equipment interface (such as shelf load ≥1 ton/㎡).
1.3 Chile: The demand for precise temperature control and cross-border logistics connection for fruit export
Chile is the world’s largest exporter of cherries (350,000 tons in 2023). The core of its storage is the seamless connection from orchard to port:
Precooling and grading: Cherries need to enter the 0-2℃ precooling warehouse within 2 hours after picking. The warehouse needs to be equipped with differential pressure precooling equipment (wind speed ≥ 2m/s) and automatic sorting line (sorting efficiency ≥ 3 tons/hour).
Cross-border adaptation: The warehouse needs to be close to the port (such as the Port of Valparaiso) and meet international cold chain standards (such as ISO 22000 certification). The walls and roofs need to be coated with salt spray resistant coating (salt spray test ≥ 1000 hours).
1.4 Colombia: The demand for intensification and flexibility of small farmers of coffee/flowers
Colombia is the world’s second largest coffee exporter (13 million bags in 2023), mainly planted by small farmers (average planting area per household < 3 hectares). Its storage needs emphasize:
Intensive sharing: multiple small farmers share warehouses (single warehouse service radius ≤ 20 kilometers), reducing the construction cost of individual farmers.
Flexible expansion: The coffee harvest season (November-February) overlaps with the flower export season (December-February), and the warehouse needs to support modular expansion (single module area 50-100㎡, which can be quickly spliced).
2. The best solution to crack South American agricultural warehousing
In response to the diverse needs of South American agriculture, the metal office warehouse buildings (including the main body of the metal warehouse + office management area) has become the preferred solution to replace traditional warehousing with its four core advantages:
2.1 Structural performance
Some areas in South America have a tropical climate (such as the average annual temperature of 28℃ and humidity of 85% in northeastern Brazil), and some areas are prone to earthquakes (such as Chile in the Pacific Rim volcanic earthquake belt). The advantages of prefab metal warehouses are reflected in:
Corrosion resistance: hot-dip galvanized steel plates (zinc layer thickness ≥ 275g/㎡) + polyurethane edge sealing, salt spray test ≥ 1500 hours (applicable to coastal areas of Colombia).
Seismic resistance: The self-weight of the light steel structure is only 1/5 of that of concrete, and the earthquake response acceleration is ≤0.3g (in line with the Chilean building seismic standard NCh433.Of96).
High temperature resistance: The roof adopts heat-insulating sandwich panels (outer aluminum-zinc plate + 150mm thick polyurethane in the middle), and the indoor temperature in summer is 8-10℃ lower than that of traditional sheds (measured data in Mato Grosso State, Brazil).
2.2 Functional design
South American agricultural enterprises (especially family farms and cooperatives) often face the problem of separation of storage areas and office areas and low management efficiency. The metal office warehouse solves this difficulty through layered/regional design:
The bottom storage area: set up a large-span loading and unloading platform (width ≥8 meters), matching forklifts (maximum lifting height 6 meters) and trailers (maximum load 30 tons) operations.
The second floor office area: light steel frame + glass curtain wall, set up weighing area (accuracy ±5kg), quality inspection laboratory (area ≥50㎡), customer reception area, realize storage and trading (such as the on-site auction function of the Argentine beef warehouse).
2.3 Prefabricated construction
South American agriculture is characterized by strong seasonality and fast capital turnover (such as the Brazilian soybean harvest season is only 2 months). The construction cycle of traditional concrete warehouses takes 6-12 months, while prefabricated metal warehouses can achieve:
Modular production: prefabricated walls, roofs, beams and columns (accuracy ±2mm) in the factory, only bolts are needed on site, and the construction cycle is shortened to 2-4 weeks (Colombian coffee warehouse case: only 28 days from signing to production).
Low-cost transportation: modular components are small in size (the maximum size of a single module is 12m×3m×4m), and can be shipped by container shipping (the freight from Brazil to Argentina is 40% lower than that of full truck transportation).
Flexible transformation: In the later stage, the mezzanine (bearing capacity ≥500kg/㎡) and storage area can be expanded according to demand (module splicing error ≤5mm) to meet the needs of small farmers to expand the scale of planting.
2.4 Economical
The hidden costs of agricultural storage in South America (such as loss and maintenance) account for up to 30%. Metal warehouse building reduce comprehensive costs in the following ways:
Low maintenance costs: The service life of metal surface treatment (polyester powder coating) is ≥25 years, and no frequent renovation is required (wooden warehouses need to replace the roof every 5 years, and the average annual maintenance cost is 20% higher).
High storage efficiency: The large span design (span of 20-40 meters) reduces the occupation of column grids and increases space utilization by 30% (the column spacing of traditional warehouse is 6 meters, and the column spacing of metal warehouse is 12 meters).
Policy subsidies: Brazil, Argentina and other countries provide tax breaks for agricultural modernization facilities (for example, Brazil’s “Agricultural Investment Law” stipulates that metal warehouse investment can be deducted from 15% income tax).

Chile earthquake version: Adopting buckling restrained support (BRB) + steel frame-support structure, the seismic response is reduced by 40%, in line with NCh433.Of96 standard.
Colombia shared version: Design modular combination units (single module 50㎡), support farmers to rent according to planting area (minimum rental unit 50㎡/year), and reduce the initial investment of small farmers.
3.2 One-stop service from design to operation
Canlong Group breaks the traditional model of “delivery is the end” and provides services covering the entire life cycle:
Preliminary planning: Cooperate with local agricultural institutions (such as the Brazilian Agricultural Research Company EMBRAPA) to calculate storage capacity (based on crop yield, harvest cycle, and transportation radius) to avoid “building too big and idle” or “building too small and not enough”.
Mid-term construction: Send a team to provide on-site guidance to ensure compliance with local building regulations (such as Argentina’s IRAM 11609 structural standard).
Post-operation: Provide storage management training (support Spanish/Portuguese), and provide supporting cold chain equipment operation and maintenance services (such as regular inspections of refrigeration units).
3.3 Technological innovation
In response to the unique challenges of South American agriculture, Canglong Group has developed a number of patented technologies:
Tropical moisture-proof patent: Add a “breathing paper + waterproof membrane” composite layer (moisture permeability ≤10g/(㎡·24h)) at the bottom of the metal sandwich panel to solve the problem of wall condensation in high humidity environments (verification of the project in northeastern Brazil: the condensation rate dropped from 35% to 5%).
Fast refrigeration patent: Develop an “evaporative condensation + solar-assisted” refrigeration system (energy consumption is 30% lower than that of traditional units), suitable for areas with unstable power supply such as Chile and Argentina.
Wind-resistant reinforcement patent: Use “cable + anchor” structure (wind resistance level ≥14) to ensure the safety of warehouses in coastal areas of Colombia during the hurricane season (During Hurricane Emma in 2023, Canglong warehouses were zero damaged).
