Cooperation with professional testing institutions: In order to further ensure the compatibility of our products with international standards, we have established long-term cooperative relationships with professional and authoritative testing institutions such as SGS, TÜV and Bureau Veritas. These institutions provide us with professional third-party testing services, such as mechanical properties testing, chemical safety testing, environmental standards testing, etc.

We attach great importance to customer feedback and regard it as an important basis for quality improvement. Any customer feedback will be carefully recorded and analyzed so that we can continuously optimize our products and improve service quality.

1. Incoming material inspection: Before production begins, we conduct a thorough inspection of all raw materials. This includes testing the physical and chemical properties of materials such as wood, metal and plastic to ensure that they meet our quality and safety standards.
2. Online full inspection during production: During the production process, we implement online full inspection for key processes. At each stage of production, professional quality control personnel will conduct detailed inspections on the products to ensure that each process is strictly carried out in accordance with established standards. This includes key indicators such as the stability of the frame, the firmness of the joints, and the uniformity of the fillings.
3. Finished product sampling: After the product is produced, we will conduct finished product sampling. This step is to ensure the quality consistency of the entire batch of products. We use random sampling to inspect the appearance of the wall panels, check whether the surface of the wall panels is flat, the size, the wear resistance and flexibility of the physical properties, etc. Through strict finished product testing, we can ensure that the wall panels meet customer needs in terms of decoration, durability and safety, and comply with industry standards and environmental protection requirements.
