The galvanized steel coils from this supplier are of top-notch quality. The material is strong and durable, and the galvanization process seems to be very well done. We have used it in our manufacturing process and the results are outstanding. Five stars！

Worst supplier They sent us a material that was completely different in size from the sample we ordered. They insisted that our measurement method was wrong, and when we finally had the supplier measure the material themselves, it was still the wrong size. They also lied about the tolerances they promised in advance, and made no apologies for wasting weeks of my time. They also refused to refund the money, and as a result of the dispute, Alibaba covered the cost because it was a small amount. I recommend not doing business with them as they tell nothing but lies.
