The company has established a full process quality control system from raw material procurement to finished product delivery, equipped with professional testing equipment such as spectral analyzers, laser thickness gauges, and salt spray test chambers, and strictly implements ISO9001 quality management standards. We conduct 35 indicator tests on each batch of raw materials, set 12 key quality control points in the production process, and ensure that 100% of the finished products pass 3D measurement and load-bearing testing to ensure that the cable tray fully meets the standards in terms of dimensional accuracy, load capacity, anti-corrosion performance, and other aspects.
