These tanks utilize food-grade resin, sealing strips, and high-strength metal connecting components to ensure a robust structure. This innovative design strikes the perfect balance between strength, safety, and durability, making it ideal for a variety of applications, including domestic, industrial, and municipal water storage systems. As a trusted factory in the industry, we are committed to delivering high-quality water storage solutions that meet your needs

    1. Material and Manufacturing Process

    Safe and Reliable Water Quality

    The inner surface of the tank is made of food-grade resin materials and complies with the national Hygienic Standard for Drinking Water (GB 5749-2006).

    Long-term immersion tests show that the stored water is non-toxic, odorless, and free from contamination, making it suitable for drinking water and food-related water storage.

    Stable Structure and Long Service Life

    The tank panels adopt a square spherical reinforced structure design, ensuring even stress distribution and high overall strength.

    They can withstand high water pressure and external loads. Under normal use and maintenance conditions, the service life can exceed 30 years.
