The film is available in different classes. Each class is made use specifically intended. Some classes contain a combination of alloys that improve strength and / or chemical resistance; While other species are structurally heat-treated to maintain their resistance to corrosion. In trade a pure aluminum foil is generally considered the most resistant to chemicals and weathering, but not as strong as sign boards models alloy.

The aluminum foil is supplied in different thicknesses. In the manufacturing process, the pretreated sign boards models ingots undergo heavy rolls under massive pressure. The higher the pressure, the thinner and more aluminum. Ingots can pass through several rows of cylinders to achieve the desired level or thickness. The foil of aluminum or alloys of any kind may have a thickness of 0.006 inches to 0.080 inches. A counter, which is thinner than 0.006 is considered aluminum foil; Though something thicker than 0.080 is considered a metal plate.

In addition, it is possible to produce sign boards models foils in a wide range of ladders and gauges, the aluminum material that can be molded, pressed, stamped and anodized for almost all colors of the rainbow . It can also be combined finishes - matte, glossy and even a number of textures can be etched into foil to create a unique look. With the low price of sign boards models and high deformability is ideal for home appliances such as toys, signs and equipment.
