Ans: No. You can usually find that they have a rough surface because they just have 1-2 non-stick coats on the surface which degrades easily after a few uses and then it becomes harmful to cook food on it. Also, it won't be able to provide you with the nonstick benefits anymore. So always go for branded non-stick cookwares that have more than 3 layers of coating and have a smooth surface. Opt for matte surfaces instead of shiny ones.
