With the continuous advancement of reconstruction projects in Ukraine in railway transportation and container logistics, demand for steel with both high strength and excellent atmospheric corrosion resistance is showing a growing trend.
In practical applications, SPA-H weathering steel plate can extend service life by approximately 2–4 times compared with ordinary carbon steel under atmospheric exposure conditions, and in most cases can achieve 10–20 years of reduced painting or maintenance-free service, making it an ideal upgraded alternative to traditional carbon steel and coated steel materials.
GNEE, with a stable quality control system and strong global supply chain capability, has successfully produced, inspected, and exported 52.331 tons of SPA-H weathering steel plates to Uruguay for local container manufacturing projects, earning continuous customer recognition.

SPA-H weathering steel plates are subject to strict inspection before shipment to ensure full compliance with international standards and project requirements.
Testing includes chemical composition verification, with precise control of key weathering elements such as Cu 0.25–0.55%, Cr 0.30–1.25%, and Ni ≤0.65%, as well as non-destructive testing such as ultrasonic testing (UT), achieving a defect detection rate of ≥99.8%.
In addition, mechanical properties are strictly controlled, with yield strength ≥355 MPa and tensile strength ranging from 490–620 MPa. Dimensional tolerances are maintained within ±0.1–0.25 mm depending on plate thickness.
All test results are fully documented in the Mill Test Certificate (MTC), and third-party inspection reports (such as SGS or BV) can be provided upon request to ensure full traceability and consistent quality assurance for export projects.
All our SPA-H weathering steel plates are securely bundled and reinforced with high-strength steel straps to ensure structural stability and zero damage during loading, unloading, and international transportation.
For long-distance sea freight, each batch of steel plates undergoes strict surface protection and anti-moisture treatment before bundling. Combined with tightly locked strapping techniques, this effectively resists high humidity and salt spray conditions during ocean transport. The cargo is safely loaded into containers or shipped in bulk vessel, fully complying with international shipping standards.
We offer a variety of efficient shipping solutions, including established routes with direct transit to major Uruguayan ports such as Montevideo. The ocean transit time from China is approximately 35 to 45 days.
Furthermore, we continuously monitor and provide real-time updates on local regulatory dynamics in Uruguay, including import tariffs, value-added tax (VAT), and various customs clearance and licensing requirements for weathering structural steel products, ensuring smooth customs clearance and a secure delivery to your project site.
