Supporting Vietnam's Infrastructure: GNEE Steel Delivers Bulk A572 Grade 50 High-Strength Steel

With the accelerated progress of Vietnam's infrastructure construction, the demand for high-strength steel is growing increasingly. Recently, GNEE Steel has completed the delivery of 1,500 tons of A572 Grade 50 high-strength steel customized for the Hanoi-Haiphong Expressway project in Vietnam. This batch of steel will be used for bridge load-bearing structures and pavement paving, providing core material support for the smooth construction of the expressway.

As a key livelihood project in Vietnam, the expressway project has strict requirements for the strength, weather resistance and welding performance of steel. A572 Grade 50, as a high-strength low-alloy (HSLA) steel plate, has a yield strength of up to 345MPa, making it an ideal choice for infrastructure projects. However, Vietnam's high-temperature and high-humidity climate requires the steel to have excellent rust resistance. During the production process, the biggest challenge for the team was how to ensure the welding toughness of the steel while improving its rust resistance. After repeated tests, the technical team treated the surface of the steel plates and added trace nickel elements to the steel to enhance its corrosion resistance. During the production period, the Vietnamese customer happened to visit the factory. After seeing the automated rust-proof treatment production line and precise mechanical property testing equipment in the workshop, the customer stated on the spot: "GNEE's production capacity has given us complete confidence." Among them, the core A572 Grade 50 HSLA steel plate for infrastructure construction has undergone weather resistance tests simulating Vietnam's climatic conditions, and its rust resistance far exceeds the project requirements.

"The expressway project has a tight schedule and heavy tasks. GNEE not only delivered the steel on time but also sent technical personnel to guide the welding process on site, solving our major problem," introduced Mr. Nguyen, the person in charge of the Vietnamese project

Previously, due to insufficient strength of local steel, the construction of the project's bridge structure was once suspended. The A572 Grade 50 high-strength steel provided by GNEE not only meets the strength requirements but also the joint strength after welding has been increased by 15%, effectively ensuring the construction quality. It is understood that after this batch of steel is put into use, the bearing capacity of the bridge has been increased by 20% compared with the original design, which can meet the traffic needs of heavy trucks.

To ensure the smooth delivery of the steel, the GNEE team fully considered Vietnam's logistics conditions, cut the steel plates into sizes that meet local transportation standards, and used waterproof and moisture-proof materials for packaging to avoid rain erosion during transportation. From order confirmation to final delivery, it only took 40 days, 10 days shorter than the customer's expectation. This cooperation has made GNEE Steel an important steel supplier for Vietnam's infrastructure projects, and currently, 3 Vietnamese infrastructure projects have sent purchase intentions to GNEE.

With the in-depth advancement of the Belt and Road Initiative, GNEE Steel will continue to focus on the overseas infrastructure market, optimize the production processes of high-strength steel such as A572 Grade 50, provide high-quality steel for more overseas infrastructure projects, and contribute to the development of global infrastructure construction.
