Observe the appearance
The surface of real Dong Peng tiles is smooth and flat, without obvious color difference and defects. However, branded tiles often have rough surfaces and uneven colors, which are obviously different from genuine tiles.
Check the certificate and test report
The real Dong Peng tiles will have a complete certificate and test report with clear handwriting and complete contents. Brand tiles often have no certificate or test report, or the handwriting is vague and the content is incomplete.
Choose formal channels to buy.
Remind everyone to choose formal channels to buy Dong Peng tiles and avoid buying brand tiles. At the same time, if you find that there are quality problems in the purchased Dong Peng tiles, you should contact the manufacturers or businesses in time to protect your rights.
