When the tube arrives, we need to remove rust to ensure the quality of the product. After galvanizing, the surface of the rusty pipe will not be tidy. After the raw material pipes of the spiral screw pile arrive, we will cut the pipes. According to the length of the pile required by the customer, we will cut the appropriate pipe. Generally, we will complete the cutting on the machine with 5 or so pipes. We strictly require the accuracy of the size. When cutting the tube, the tube will not be cut short, and even be required to be flattened. We will pick out the unqualified products and will not ship it.
