■Flat PanelBack side of a typical sign13Flat back panel prevents dirt, corrosion and snowThis panel has a flat structure and parts made of extruded aluminum (Grooved Upper Flat, Flat, Grooved Lower Flat) are firmly fitted together. Because the panel and bolt groove are integrated, there is no danger of coming off, and because of the double structure of the aluminum plate made of extruded material and the strong fitting structure, there is no danger of coming off or slipping. Anti-corrosion surface finish prevents dirt, suppresses corrosion and oxidation, and is not affected by salt damage. In addition, because the back is flat and it is hard to get snow, it is also suitable for regions where it snows a lot.
