How is the quality of the stainless steel material for the water tank?
The stainless steel materials used in our water tanks are sourced from China Hongwang Group, a leading enterprise in metal new materials.
The stainless steel materials used in our water tanks are sourced from China’s leading metal new materials enterprises, Jiangsu Delong and Hongwang Group.
These companies specialize in the research and production of stainless steel, silicon steel, titanium alloys, and other metal materials. With strict quality management systems and advanced technological capabilities, their products are widely used in industries such as aerospace, marine engineering, and equipment manufacturing.


The quality of a water tank is closely linked to the materials used, especially when selecting food-grade stainless steel. The SUS201, SUS304, and SUS316 stainless steels we use are known for their excellent corrosion resistance, oxidation resistance, and high-temperature performance, ensuring that the tanks can be used in various environments over the long term without compromising water quality.

- SUS201 Stainless Steel: As an economical stainless steel, SUS201 offers high strength and corrosion resistance, making it widely used in applications requiring some level of corrosion resistance. Although its corrosion resistance is slightly lower than SUS304 and SUS316, it still meets most industrial and household water storage needs while controlling costs.
- SUS304 Stainless Steel: SUS304 is one of the most commonly used stainless steels, offering excellent corrosion resistance, oxidation resistance, and good processing performance. It is often used in fields where water quality is critical, such as food and medical industries. Its corrosion resistance effectively prevents external environmental factors from impacting the water quality inside the tank, making it an ideal material for food-grade tanks.
- SUS316 Stainless Steel: SUS316 stainless steel, which contains molybdenum, offers even greater corrosion resistance, especially in seawater or chloride environments. It is currently the most corrosion-resistant food-grade stainless steel and is commonly used in medical, chemical, and marine engineering fields. For high-demand water quality and harsh environments, SUS316 provides the best protection.


The stainless steel materials meet international standards for quality, performance, and environmental sustainability, ensuring that each batch has outstanding corrosion resistance and strength. They are capable of meeting various water storage needs, particularly in applications requiring high water quality.
By collaborating with major Chinese steel enterprises, we are able to provide customers with high-quality, reliable, and safe food-grade stainless steel water tanks that maintain excellent performance over long-term use, avoid water contamination, and ensure the health and safety of our customers.
