The building materials industry is plagued by the practice of passing off inferior products as high-quality ones; low-priced products often feature altered formulations, reduced thickness, and the use of substandard recycled materials, which shortens their service life. Consumers should pay attention to the physical and chemical properties of the panels and verify their authenticity by scratching a sample, checking for odors, and assessing the weight, to avoid being misled by sales pitches. When choosing a retail outlet, avoid stalls that do not provide quality inspection reports and prioritize reputable retailers.
