The present invention relates to a metal mesh, and more particularly to a coated metal mesh, a coating apparatus for manufacturing the metal mesh and a manufacturing process.

In general, the metal mesh can be classified in various ways depending on the intended use, the most commonly used among them is the insect screen (防蟲網) or security screen (防 犯 網).

Insect screen refers to a net with tight eyes to prevent invasion of insects and rats at the opening for air circulation, and it has a form similar to that of a insect screen and is not easily damaged by external intruders. Refers to nets processed from materials.

As such a insect screen and a method network, stainless steel, iron, brass, copper, saran and the like are used. These metal insect screens and method nets (hereinafter referred to as 'metal nets') are exposed to the exterior of buildings and are very susceptible to salinity due to contamination or corrosion depending on polluted air or temperature or extreme climatic conditions (rain or snow). . In order to solve this problem, the metal mesh manufactured is painted and used.

However, when paint is applied to a metal net, various problems arise. That is, the worker paints or paints with a spray or the like and then dries in a natural state. However, if a worker paints every day, a lot of time is required for painting, an unnecessarily large amount of drying time after painting is required, and the painting work has to go through the hands of the worker. In addition, in the form of spraying, even though there is a slight time-saving effect, the drying time after painting is also unnecessary unnecessarily, and above all, the paint particles sprayed from the spray are sucked into the worker's hopper and are very good for worker's health. It's bad. In addition, the painted surface of the metal mesh thus painted is very uneven, and over time, the paint is easily released and corrosion occurs easily. These problems eventually lead to a decrease in productivity and an increase in costs, leading not only to economic waste, but also to environmental pollution.

Therefore, the present invention has been made to solve the problems described above as a metal mesh that can improve the environment-friendly manufacturing process, increase the work efficiency, prevent unevenness of the coating, beautiful appearance and excellent corrosion resistance due to the variety of coloring range The main purpose is to provide a metal mesh coating apparatus and its manufacturing process for producing a.
