The base material of the zinc steel fence profile is high temperature hot dipping zinc material. Hot dipping zinc means that the high quality steel is put into the zinc liquid pool at several thousand degrees, and after soaking for a certain time, the zinc liquid will penetrate into the steel, making it form a special zinc steel alloy. The surface of the hot dipping zinc material can not rust for 30 years in the field environment without any treatment, such as: Highway guardrail, high voltage tower are made of high temperature hot dip zinc material, its rust prevention as long as 30 years, completely solved the problem between rust prevention, beauty and safety for many years.
