It has developed in the direction of efficient production.

Materials corresponding to raw materials are usually transported from the production site before processing and stored until processing, and there are quite a lot of cases in which the material is stored in the air.

In this case, if processed as it is, the two parts made of wires such as insect screens are rapidly oxidized or the strength of the part is remarkably weakened by contaminants, causing problems such as breakage.

In addition, in the case of the screw, the surface is formed to be curved, so that it is difficult to remove foreign substances on the surface or to process the surface by polishing.
