Engineered to meet strict structural standards and withstand the challenging climatic conditions of South America.
Chile's geography presents some of the most diverse and extreme environmental challenges in the world. From the hyper-arid, high-UV conditions of the Atacama Desert in the north to the highly saline coastal zones of Valparaíso and San Antonio, and the high-precipitation, humid regions of the south, materials used in construction and infrastructure must possess exceptional durability. Galvalume Steel Sheets (55% Aluminum-Zinc alloy coated steel) have emerged as the premier material choice across Chilean commercial, residential, and industrial sectors.
The unique composition of Galvalume—combining the barrier protection of aluminum with the sacrificial protection of zinc—offers up to three to six times the corrosion resistance of traditional galvanized steel (GI) in marine and industrial environments. For Chilean project managers, engineers, and procurement officers, selecting the right coating weight (such as AZ150) is critical to ensuring structural longevity, reducing lifecycle maintenance costs, and meeting local building codes (including seismic and wind load requirements).

Recyclable & Eco-Friendly Material
From northern copper mines to southern agricultural hubs, our Galvalume steel sheets are engineered for specific regional demands.
In the Antofagasta and Atacama regions, copper mining facilities require robust roofing and cladding. Our heavy-coated Galvalume sheets (AZ150/AZ200) resist the abrasive action of mineral dust and chemical exposure from processing plants, ensuring uninterrupted operations.
Valparaíso, San Antonio, and Iquique serve as major logistics hubs. Warehouses in these port cities face constant salt spray. Utilizing Aluzinc steel panels prevents premature edge creep and red rust, significantly extending the service life of logistics facilities.
In the Central Valley and southern Los Lagos region, agriculture and salmon farming facilities demand materials that resist high humidity and organic emissions. Prepainted Galvalume (PPGL) sheets provide chemical resistance and thermal regulation for livestock housing.
As a leading Chinese steel manufacturer, Ningbo Puppet Steel Co., Ltd. bridges the gap between high-volume, cost-efficient production and the precise technical standards required by the Chilean market. Our state-of-the-art facilities in Ningbo leverage advanced cold rolling and hot-dipped Aluzinc coating lines to deliver consistent quality.
We understand the logistics challenges of shipping to South America. Our close proximity to the Port of Ningbo allows us to secure competitive freight rates and direct shipping routes to major Chilean ports like Valparaíso, San Antonio, and Iquique. Furthermore, we offer custom packaging solutions (including VCI anti-rust paper and steel bands) to ensure that your coils and sheets arrive free of transit-induced oxidation or physical damage.
Our Galvalume sheets are strictly manufactured to meet international standards, ensuring seamless integration into Chilean engineering projects:
Aligning with Chile's national strategy for carbon neutrality and sustainable construction practices.
Chile's energy efficiency regulations for new buildings place a strong emphasis on thermal insulation. Galvalume steel has a highly reflective surface that bounces off solar radiation, keeping buildings cooler in the hot summer months of Santiago and the northern regions. This significantly reduces HVAC energy consumption, contributing to LEED certification points for green building projects.
Steel is 100% recyclable, and the extended lifespan of Galvalume means fewer material replacements over a building's lifecycle. By choosing AZ150 Aluzinc sheets, Chilean developers minimize the environmental footprint associated with manufacturing, transporting, and installing replacement roofing materials, aligning with the country's circular economy goals.

Galvanized steel (GI) is coated with 100% zinc, which provides sacrificial protection but can corrode relatively quickly in high-salinity coastal areas like Valparaíso. Galvalume (GL) is coated with an alloy of 55% aluminum, 43.4% zinc, and 1.6% silicon. The aluminum forms a highly stable alumina barrier film that resists atmospheric corrosion, while the zinc provides galvanic protection at cut edges. In saline and industrial environments, Galvalume lasts 3 to 6 times longer than galvanized steel of equivalent coating thickness.
For harsh mining environments, such as those in the Atacama and Antofagasta regions, we strongly recommend a minimum coating weight of AZ150 (150 g/m² double-sided). For highly corrosive processing areas or structures close to the coast, AZ200 is preferred. These heavier coatings provide the necessary thickness to withstand abrasive dust, high UV radiation, and atmospheric chemical exposure.
Yes. Our Galvalume and galvanized steel sheets are manufactured in strict compliance with international standards such as ASTM A792/A792M and EN 10346. For structural applications requiring high yield strength (such as light-gauge steel framing or industrial roof decking), we supply high-strength grades like G550 (550 MPa minimum yield strength), which meet the mechanical performance requirements specified in Chilean seismic design codes.
The typical ocean transit time from Ningbo Port (China) to major Chilean ports (Valparaíso, San Antonio, Iquique) ranges from 35 to 45 days, depending on the shipping line and route (direct vs. transshipment). We coordinate closely with leading maritime carriers to secure reliable space allocations and minimize port delays.
We use export-grade seaworthy packaging for all shipments. Coils are wrapped in anti-corrosion VCI (Volatile Corrosion Inhibitor) paper, followed by a protective plastic film, and then encased in a steel outer shell. The assembly is secured with heavy-duty steel strapping bands and mounted on solid wooden or steel skids. This multi-layered protection prevents moisture ingress and physical deformation during ocean transit and handling.
