Engineered to resist the corrosive moisture of the Paraná river basin and the intense solar heat of South America.
Paraguay represents one of the fastest-growing economies in Latin America. With major logistical corridor investments such as the Corredor Bioceánico and massive urbanization in metropolitan Asunción, Ciudad del Este, and Encarnación, the demand for long-lasting, structural building materials is skyrocketing.
Industrial warehousing, agricultural grain storage facilities (silos), and manufacturing plants require roofing materials that can withstand intense subtropical weather conditions. In Paraguay, high relative humidity combined with intense ultraviolet radiation accelerated by geographical factors poses a severe corrosion threat to standard metal roofs.
Consequently, local distributors, EPC contractors, and structural engineers are transitioning from traditional galvanized sheets to advanced Galvalume (Aluzinc) and pre-painted (PPGI/PPGL) roofing profiles. These modern materials guarantee structural integrity for up to 30–50 years, significantly reducing maintenance overheads for agricultural and industrial operations across the country.
Paraguay's climate is divided into two distinct zones: the humid, subtropical Eastern region and the semi-arid, hot Chaco region. Roofing systems must be adapted to both:
Importing metal roofing into Paraguay requires compliance with both international baselines and local MERCOSUR-specific regulations.
For high-humidity zones along the Paraguay and Paraná Rivers, we specify Z275 galvanized (zinc coating of 275g/m²) or AZ150 galvalume (aluminum-zinc coating of 150g/m²). This ensures active sacrificial protection and prevents edge rust.
Our manufacturing parameters align with the testing protocols mandated by the Instituto Nacional de Tecnología, Normalización y Metrología (INTN) in Paraguay, ensuring zero customs delays and full project approval safety.
We supply true-to-spec base metal thickness (BMT) from 0.3mm to 0.8mm. Avoid the risk of cheap sub-standard "nominal thickness" sheets that fail under the mechanical loads of industrial roof construction.

Efficient delivery routes bypassing transit bottlenecks to ensure your raw materials arrive intact and on schedule.
Since Paraguay is a landlocked nation, shipping metal coils and sheets requires specialized fluvial knowledge. Most of our shipments route from the Ningbo Deepwater Port to ocean hub terminals in Buenos Aires (Argentina) or Montevideo (Uruguay).
From these hubs, the cargo is transferred to river barges that travel upstream along the Paraná-Paraguay waterway system, arriving directly at major ports in the Asunción metropolitan area (such as Puerto Fenix, Puerto Terport, or Puerto Caacupemí). We coordinate with trusted local freight forwarding agencies to ensure smooth transshipment processes, minimizing demurrage costs.
Shipping steel sheets over long sea and river voyages exposes them to extreme humidity fluctuations. If raw steel is exposed to sea salt mist, white rust will destroy the zinc coating before arrival.
To eliminate this threat, Puppet Steel employs heavy-duty export wrapping consisting of multi-layer waterproof VCI (Volatile Corrosion Inhibitor) paper, galvanized metal outer protective rings, robust structural wooden/metal pallets, and heavy strapping. Desiccant gel packs are inserted into each package to absorb ambient moisture during transport across different climate zones.
Customize your profile, thickness, zinc density, color code, and surface texture.
From industrial projects in Mariano Roque Alonso to large agricultural structures in Alto Paraná.
In regions such as Alto Paraná and Itapúa, massive grain handling complexes rely on G550 Aluzinc sheeting. Due to high humidity and exposure to organic chemicals, standard steel fails, whereas our AZ150 anti-fingerprint coating protects the silos for decades.
For warehousing around Asunción and Limpio, PPGI profile sheets like 686mm IBR or sinusoidal wave sheets provide cost-effective cladding. Their high heat reflectivity limits interior heat gain, saving energy costs.
Government infrastructure housing initiatives require aesthetic and durable roofs. Our color stone-coated metal roof tiles and prepainted corrugated sheets offer modern curb appeal with long warranties.
Common questions from South American buyers regarding custom steel import from China to Paraguay.
Ocean transit from Ningbo port to River Plate hubs (Buenos Aires or Montevideo) takes approximately 45 to 55 days. Once transferred to barges, transport upstream via the Paraguay-Paraná river system to Asunción-area ports takes an additional 10 to 15 days, depending on seasonal river levels.
Z275 refers to pure zinc coating (275g/m² total two sides) while AZ150 refers to aluminum-zinc alloy (150g/m²). For tropical climates, AZ150 offers superior corrosion resistance in flat exposures, whereas Z275 provides sacrificial edge protection. We recommend AZ150 for general roofing and silo structures, and Z275 for coastal or wet animal housing environments.
Yes. Our manufacturing standards comply with JIS G3302, G3321, ASTM A792, and European EN 10346 norms, which correspond to the requirements specified by INTN in Paraguay. We issue Factory Inspection Certificates and third-party SGS testing reports upon request.
We use heavy-duty seaworthy packaging, including VCI anti-corrosion barrier paper, outer galvanized steel sleeves, thick plastic corner protectors, and dense wood/steel pallets. Additionally, we place high-capacity moisture absorbers within the packaging wraps to eliminate condensation during transit.
Yes. We have multiple profiling machines that can roll-form coils into IBR profile, corrugated sinusoidal profiles, trapezoidal profiles, and T-type structural wall panels. If you provide your design drawings, we can custom-manufacture the required profiles accordingly.
