Aluminum traffic sign blanks

Feb 21, 2023

On the road, we often see road traffic signs, traffic signs, and safety signs. These signs have different colors such as blue, yellow, red, etc. Different colors and shapes have different meanings. For example, a red inverted triangle street sign is generally a prohibition sign, and a yellow inverted triangle is generally a warning sign. The guide signs we often see are generally set as rectangular blue signs, and the direction signs are set as round blue signs. Do you know what material these signs are made of?

Bottom plate materials: There are many kinds of materials for the bottom plates of traffic signs, but most manufacturers use aluminum alloys. Aluminum traffic sign blanks are widely used because of their light weight and corrosion resistance. There are also extruded aluminum alloy profiles and aluminum composite panels on the market. The convenient manufacturing method is to use the molten electrode MIG gas shielded welding technology for spot welding. There is also a traditional riveting method, that is, there are many riveting processes and low efficiency.

Reflective material
Highway traffic sign boards should be made of reflective film materials that meet the requirements of the current "Highway Traffic Sign Reflective Film". When using reflective film materials on traffic sign boards, one and two reflective films should be used on highways and first-class highways, namely imported 3M diamond grade and imported 3M strong reflective film, but the cost is relatively high. Class II and Class III highway traffic signs should use Class III and Class IV reflective films, that is, imported 3M engineering-grade reflective film, which has a relatively low cost. Grade 4 highways should adopt Grade 4 and Grade 5 reflective films, that is, Grade 5 reflective films for domestic projects.

Aluminum Co., Ltd. specializes in the production of various special aluminum traffic sign blanks, which are processed from 1100, 3003, and 5052 aluminum plates, which are easy to shape and surface treatment; the surface has fine lines and has a refraction effect. The three-dimensional metal feel is quite strong; customized aluminum signs It also has the characteristics of temperature resistance, corrosion resistance, sun protection, water resistance and oxidation resistance; it is durable and widely applicable.

Product thickness: The thickness is 1.5mm, 2.0mm, 2.5mm, 3.0mm, 4.0mm and other specifications. The maximum size of custom cut aluminum sign blanks can reach 1500x7000mm.
