What are the forms and material classifications of signs?

Signs are very common in our daily life, but signs can be divided into wooden signs, plastic signs and metal signs because of the different production materials, which is dazzling, so how is the sign classified? And what forms does it take?

Material classification:

(1), smooth identification signs: the picture or board surface has oil, very smooth.

(2), acrylic identification signs: acrylic material as the main material of the board.

(3) Luminous material signs: luminous material signs (that is, we usually say neon lights)

(4), electro-optical plate identification signs: with light-emitting diodes or luminous tubes to achieve monochrome or color performance effects.

(5), metal signs: in the absence of a specially specified board surface, use metal as the main material of the board or text of the sign and use metal as the main carrier of the sign.

Morphological classification:

(1) Vertical: The whole proportion is relatively long vertically, and the whole face is generally used as a sign.

(2) Ground column: horizontal, vertical and three-dimensional identification signs marked on some fixed structures on the ground

(3) Horizontal: The whole proportion is relatively long horizontally, and the whole face is used as a sign, which can be seen on the walls of small shops and large buildings.

(4), protrusion: protrusion on the wall of the building, in addition to the back of the whole face or there are two sides of the wall, both sides are used as advertising carriers of identification signs, such as three side flip signs.

(5) Roof type: refers to the setting of some fixed structures on the roof of a building, and the plate-shaped living cube or magic identification signs hung or affixed on it.
