Quality Control

International Production Standards Certification: The company is certified under the ISO 9001 quality management system, and its products comply with EU CE safety standards and international food-grade FDA certification requirements, ensuring global market access qualifications.

Production Quality Advantages: Utilizing a German-imported microcomputer-controlled winding system, achieving ±0.5mm precision control, combined with a special resin formula, the product's corrosion resistance is increased by 30%, its service life exceeds 50 years, and engineering costs are reduced by 30% compared to traditional materials.

Quality Assurance Phase
We have established a comprehensive quality inspection system, equipped with 12 types of professional testing equipment including Brinell hardness testers, ultrasonic thickness gauges, and electronic universal testing machines. We implement seven inspection procedures from raw material entry to finished product shipment, ensuring that each batch of products meets stringent standards for pressure resistance, aging resistance, and leak-proof performance.
 
Warranty Policy
We are implementing a "dual warranty + lifetime" quality assurance policy – ​​a basic warranty of 3 years covering manufacturing defects; an extended warranty of 5 years addressing performance degradation; and lifetime free technical consultation and maintenance guidance to ensure worry-free use for the entire product lifecycle.

FAQ

  • Q What are the testing standards for fiberglass products?

    A
    We adhere to the GB/T 21238-2016 national standard and the ASTM D3299 international standard, covering 28 performance indicators including corrosion resistance, temperature resistance, and aging resistance.

  • Q How is quality control performed for large storage tanks manufactured on-site?

    A
    A mobile testing station is used to monitor winding tension, resin ratio, and curing temperature in real time.  Key points are subjected to ultrasonic non-destructive testing by a third-party organization.

  • Q What are the special requirements for quality inspection of export products?

    A
    We add salt spray testing, UV aging testing, and food contact safety testing to ensure compliance with the requirements of the importing country's customs and health departments.

  • Q How often are the quality inspection equipment calibrated?

    A
    All testing equipment is calibrated quarterly by a provincial metrology institute to ensure a testing accuracy error of ≤1%.

  • Q How can product production records be traced?

    A
    Each batch of products is equipped with a unique QR code. Scanning the code allows you to query raw material batches, production teams, testing data, and logistics information, enabling full traceability throughout the process.
