Quality Control
Because we put the quality of our products and our customers first, quality control management is a priority at ZY. We have been granted the ISO9001-2008 certificate, and have received the production license for our railway products from China's Railway Ministry. Our production process is state of the art, with an advanced mold-processing center, two production lines for rail clips, heat treatment lines, and 20 production lines for railway fasteners. We also have a full line of inspecting equipment.
