Oriental Yuhong Subsidiary Awarded NORSOK M-501 Certification, Marine Anti-Corrosion Tech Reaches International Standards

Hz info:Hongjia Industrial Coatings, under Beijing Oriental Yuhong Waterproof Technology Co., Ltd. (Oriental Yuhong), has officially passed the internationally authoritative NORSOK M501 certification for its high-performance protection system developed specifically for harsh marine environments. This achievement marks a significant breakthrough for the company in the field of marine protection. The full passage of test items no. 7A and no. 1B demonstrates Oriental Yuhong's substantial accumulated expertise in marine anti-corrosion technology.

In the marine protection sector, after three years of dedicated research and development, Hongjia Industrial Coatings has developed two customized protection systems for the submersed zone and atmospheric zone, respectively, within marine environments. Following over eight months of rigorous testing, the relevant products met all certification requirements in key indicators such as corrosion resistance and durability. In September 2025, at the Marine Protection Conference held in Sanya, Hainan, Yang Xiaoquan, R&D Manager at Hongjia Industrial Coatings, delivered a keynote report on the integrated application of anti-corrosion and anti-fouling solutions for marine environments. He detailed the company's technological breakthroughs in addressing the complex marine conditions of the South China Sea, characterized by high temperatures, high humidity, high salinity, and strong radiation.

It is noteworthy that Hongjia's solvent-free epoxy drinking water coating has already been put into use at five major aquaculture bases in Hainan. This product is specifically designed for aquaculture facilities, features environmental friendliness and strong adhesion, and has obtained U.S. FDA food safety certification, indicating a safety standard significantly higher than that of conventional coating products.

According to HuiZheng Information, Hongjia Industrial Coatings Co., Ltd. was established in June 2022 with a registered capital of 500 million RMB and is a wholly-owned subsidiary of Oriental Yuhong. Currently, the company has established business layouts across four industrial systems: infrastructure, bridge protection, petrochemicals, and the energy industry. Its products and services cover water industry facilities and marine engineering equipment, among other emerging fields. In terms of production capacity construction, in December 2022, Oriental Yuhong's subsidiary, DAW SE, initiated the "Hongjia Coatings Workshop Technical Renovation Project." This project involves establishing new industrial coating production lines within vacant areas of the solvent-based coatings workshop at the Hangzhou Jiande plant. Upon completion, the project will achieve an annual production capacity of 4,000 tons of industrial coatings, 150 tons of vinyl ester resin coatings, and 1,500 tons of ground mineral grouting materials.

In the traditional industrial coatings sector, Hongjia Industrial Coatings also demonstrates strong market competitiveness. The company recently secured several significant contracts consecutively. It successfully won bids for five sections of the China Petrochemical Corporation (Sinopec) 2025 annual framework agreement, covering common paints, water-based paints, and solvent-free coatings, among others. This marks the third consecutive year Hongjia has been selected as a Sinopec supplier, with the scope of supplied products continuously expanding. This fully reflects the high recognition of its comprehensive strength in products, technology, and service by this central state-owned enterprise giant. Furthermore, in the Special Economic Zone Construction Engineering Steel Structure Paint Procurement Project in June 2025, Hongjia became the preferred winning bidder with a quoted price of 13.42 million RMB, further consolidating its position in the industrial coatings market.

While expanding its market reach, Hongjia also actively leverages industry platforms to disseminate its technological influence. At the 9th China Petroleum & Petrochemical Corrosion and Protection Technology Exchange Conference held in Tianjin in July 2025, Yang Xiaoquan, the company's R&D Manager, was invited to deliver a keynote report. He focused on introducing Hongjia's graphene zinc-rich and super corrosion-resistant material solutions. These solutions cover multiple application scenarios such as refining, storage and transportation, and power generation, providing reliable support for the long-term protection and safe operation of key equipment in the petroleum and chemical industry through innovative technologies.

With the rapid development of the global marine economy, the demand for protection of marine engineering equipment continues to grow. In the future, Oriental Yuhong will continue to consolidate its industrial foundation, leverage its professional advantages, contribute high-level scientific and technological innovation achievements to support the high-quality and sustainable development of the marine economy, provide professional technical support for the safe operation and long-term protection of high-end equipment, and strive to become a leading domestic and internationally renowned industrial coatings brand enterprise.
