On October 20, 2021, we conducted random sampling on a powder-coated steel fence order to send to the institute of transport science and technology (ITST) to test the technical specifications of the product surface. The result showed a very well performance of the sample that we passed all the requirements. And the coating thickness measured at 230 micrometers has dramatically surpassed the popular thickness of 110 – 140 micrometers. We will summarize the important information below.
