GNEE Steel's S355JR Alloy Steel Plates Shipped To Poland

Recently, a heavy machinery manufacturing plant in Warsaw, Poland, received 1,200 tons of S355JR hot-rolled alloy steel plates from GNEE Steel. This batch of steel will be used for the production of booms and bases of large cranes, marking GNEE's successful entry into the European market for heavy machinery steel with its alloy steel plates. As an alloy steel plate complying with European standards, S355JR is widely used in the heavy machinery sector due to its excellent mechanical properties and processability.

For the S355JR steel plates purchased this time, the Polish customer required a yield strength of 355MPa and compliance with EN 10025 standard certification, which put forward extremely high requirements for GNEE's production processes and quality control. At the initial stage of production, the biggest challenge faced by the team was controlling the chemical composition of the steel: the customer specified that the carbon content should be maintained between 0.18% and 0.24% to ensure the steel's welding performance. The smelting workshop precisely controlled the blast furnace temperature and raw material ratio, stabilizing the carbon content at 0.21%, while adding manganese to enhance the steel's strength. During the rolling process, a computer control system was adopted to real-time monitor the thickness and temperature of the steel plates, ensuring that the dimensional accuracy of each plate meets the requirements. Among them, the core S355JR hot rolled alloy steel plate for European industrial equipment has passed certification by authoritative Polish testing institutions, with all indicators complying with European standards.

"We chose GNEE not only for its superior product quality but also for its comprehensive after-sales service," said the purchasing manager of the Polish customer. At the initial stage of order confirmation, she had doubts about the adaptability of the steel. In response, GNEE's technical team immediately provided a detailed mechanical property analysis report of the steel based on the customer's crane design drawings and recommended suitable processing technologies. During the production process, GNEE sent weekly production progress reports and testing data to the customer, allowing them to real-time track the production status. After the steel plates arrived at the Polish factory, the purchasing manager led her team to conduct a comprehensive inspection. The results showed that the yield strength and welding performance of the steel plates were better than expected, and she signed a two-year long-term cooperation agreement with GNEE on the spot.

To ensure the steel plates were not damaged during transportation, GNEE's logistics team adopted a packaging method of "wooden pallets + waterproof cloth", placing buffer pads between each plate to avoid scratches caused by collisions. Meanwhile, GNEE cooperated with European logistics companies in advance to plan the optimal transportation route, shortening the transportation time from the conventional 30 days to 22 days, ensuring the customer could put the steel into production on schedule. This delivery not only earned GNEE Steel high recognition from the Polish customer but also opened a breakthrough for expanding into the entire European heavy machinery steel market.

Currently, GNEE Steel has established an after-sales service center in Europe to provide timely technical support and spare parts supply for European customers. In the future, GNEE will continue to optimize the production processes of alloy steel plates such as S355JR, enhance the international competitiveness of its products, provide high-quality steel products and services for more European customers, and promote the sustainable development of Chinese steel brands in the European market.
