Recently, a delegation from a leading Thai engineering and construction group paid a special visit to GNEE to conduct procurement inspections and in-depth cooperation negotiations on S355JR low-alloy high-strength steel plates. This visit closely aligns with Thailand's infrastructure upgrading and industrial development needs, focusing on the application of S355JR steel plates in scenarios such as bridge construction, port engineering and machinery manufacturing.
On-site Inspection: Witnessing the High-performance Strength of S355JR Steel Plates
The delegation first went deep into the S355JR steel plate production workshop of GNEE, observing the entire production process from high-purity raw material smelting, precision controlled rolling to finished product inspection. As a core product complying with the European standard EN10025-2, S355JR steel plates have a minimum yield strength of 355MPa and a tensile strength ranging from 470MPa to 630MPa. They also boast excellent weldability and plastic deformation capacity with an elongation rate of over 21%, fully adapting to Thailand's tropical climate and complex engineering working conditions.

At the quality inspection center, the clients focused on verifying the mechanical property test reports, low sulfur and phosphorus control data, as well as welding process validation records of S355JR steel plates, and highly recognized GNEE's multi-layer quality inspection methods including online ultrasonic flaw detection and low-temperature impact testing.

In response to the special requirements of Thai engineering projects for steel weather resistance and welding efficiency, our technical team demonstrated customized solutions on site. By optimizing the alloy ratio to enhance the corrosion resistance of the products, their compatibility with multiple processes such as shielded metal arc welding and submerged arc welding is highly consistent with the standards proposed by the clients for bridge main girders and port equipment manufacturing, winning unanimous praise from the delegation.
Targeted Matching: Finalizing Key Cooperation Matters
After the visit, the two parties held a special cooperation forum. At the meeting, the Director of International Trade of GNEE gave a detailed introduction to the company's production capacity scale and global supply chain layout in the field of low-alloy high-strength steel plates, focusing on the customized service system for the Southeast Asian market, including adjusting steel plate specifications on demand, short-cycle mass production, full-process logistics tracking and localized technical support and other supporting guarantees.

Combined with Thailand's national development plan, the Thai client representatives clarified their procurement needs. The clients particularly emphasized that the products must meet the long-term service stability under tropical high-temperature and high-humidity environments, as well as the continuous welding construction requirements of large structural components.


In response to the clients' questions regarding technical parameter verification, delivery cycle and after-sales technical support, our team provided professional answers one by one, and submitted a tailor-made supply plan on site. The two parties finally reached a clear consensus on the specifications and models of S355JR steel plates, quality acceptance standards, the volume of the first batch of supply and the subsequent annual procurement plan. The clients expressed their intention for long-term cooperation on site, planning to purchase the first batch of S355JR steel plates for the port expansion pilot project.
Win-win Future: Expanding New Space for China-Thailand Cooperation
This visit by the Thai clients has not only consolidated the foundation of mutual trust for cooperation between the two parties, but also accurately matched the core material needs of Thailand's infrastructure projects.

GNEE will strictly abide by the cooperation agreement, ensure the stable supply and quality control of S355JR steel plates, and simultaneously provide localized technical guidance and after-sales support services. Taking this cooperation as a starting point, the two parties will also explore more cooperation space in weather-resistant steel plates, customized specification products and other fields, helping Thailand improve its transportation and energy network, enhance the level of manufacturing industry, and inject sustained momentum into China-Thailand economic and trade cooperation.

The successful conclusion of this inspection and exchange marks the continuous improvement of the recognition of GNEE S355JR steel plates in the high-end Southeast Asian market.
