Chain link fence is composed of galvanized steel wire, stainless steel wire or plastic-coated wire that are hooked to each other. The outer four sides are fixed with frames. Weaving machine is a special machine, which can also be divided into two types: one is a simple pre-bending machine, which only pre-bends the wire, and then the staff manually connects the pre-bent wires in series. The wide mesh surface can also be woven. The disadvantage is low efficiency; the other is a more complex pure mechanical weaving, which is pre-bent and knitted entirely by machinery. This efficiency is much higher, but it requires a one-time investment. Larger, and limited by the layout, we can only weave beyond the limit of its own wide, more than we can not weave.
