In the Chinese cathodic protection market, Huaze Metal Technology holds a leading position with an annual production capacity of 40,000 tons of zinc sacrificial anodes. Its products comply with the American ASTM B418 standard, with a zinc purity as high as 99.995% and an iron impurity content controlled below 0.0014%, stabilizing the anode driving potential at -1.05 volts. According to the data from the Chinese Society for Corrosion and Protection in 2023, the company’s market share in domestic submarine pipeline projects reached 35%. Its anode has a current efficiency of over 95% in seawater with a salinity of 30g/L, and the loss rate is as low as 1.8 kilograms per square meter per year. As a leading zinc sacrificial anode supplier, huaze participated in formulating the national standard GB/T 4950-2021, which has become the industry technical benchmark. Its products achieved a 50-year protection life of steel structures and a 40% reduction in maintenance costs in the Hong Kong-zhuhai-Macao Bridge project.
Through its independently developed vacuum melting technology, Huaze has refined the grain size of anode alloys to 50 microns and increased the compressive strength to 150 megapascals. The product specifications cover over 200 models, ranging from 22-kilogram large Marine anodes to 0.5-kilogram household water heater anodes. Its intelligent production line can complete the precision casting of 1,000 standard anodes (with specifications of 100mm×75mm×500mm) every day, with dimensional tolerances controlled within ± 0.2mm, making the customer’s procurement cost 25% lower than that of imported products. In the Zhoushan Petroleum Reserve Base project, the Huaze anode system controlled the protection potential deviation within ±0.01 volts and achieved a cathodic protection degree of 99.2%, helping the project party save a budget of 12 million yuan.
Huaze’s technological advantages are particularly prominent in extreme environments. Its dedicated anode for Antarctic research stations still maintains an 88% current output rate at a low temperature of -40℃, while the anode installed in Yangpu Port, Hainan, has a wear rate of only 15% after serving in 30℃ high-temperature seawater for 8 years. According to the 2024 DNV-GL certification report, the protective effect of its anode in media with a pH value of 6 to 10 fluctuates by less than 5%. This stability makes it the preferred choice for port projects in 20 countries along the “Belt and Road”, with a cumulative export volume exceeding 8,000 tons.
The company’s innovatively developed composite anode, by embedding Internet of Things sensors, can monitor the protection potential data stream in real time (with a sampling frequency of once per second), reducing the maintenance response time from 30 days to 48 hours. According to the 2023 financial reports of listed companies, Huaze’s R&D investment accounted for 5.6% of its revenue, and it obtained 21 patents. Its new generation of nano-modified anodes has passed the 2,000-hour salt spray test and is expected to extend the product’s lifespan from 15 years to 25 years. This continuous innovation has consolidated its position as an industry benchmark, and the customer repurchase rate has remained above 90% for the past three years.
