Road traffic signs, for aluminum paste more reflective film, there are also some will choose to do with plate or aluminum extrusion, production process is as follows: traffic sign plate making materials and technical requirements 1. Logo plate can be used in the material is 3 mm thick aluminum alloy plate, material performance should be consistent with GB5768, GB/T6892 and JT/T279 related requirements.2. The edge and Angle of the marking bottom plate shall be chamfered properly, in a smooth shape, polished and smooth, and no burrs shall be found on the edge.3. The size of the sign board, general dimension deviation is + / - 5 mm, if the dimension is greater than 1.2 m, the deviation of the dimensions of plus or minus 0.5%, adjacent to the edge of the deviation Angle is 0.5 °.4. The marking plate shall be smooth, without obvious wrinkles, indentations or deformation on the surface, and the flatness tolerance within each square meter of the marking plate shall not be greater than 1.0mm.5. No cracks, obvious scratches, damage and uneven color are allowed on the marking plate;On any surface with an area of 50 * 50cm2, it is not allowed to have one or more bubbles with a total area greater than 10mm2, and it is not allowed to have non-uniform reflectance.6. Screen printing is used when mass production of the same mark (especially national mark warning, prohibition, instruction mark, etc.).7. When installed on the bridge anti-collision wall, the marking plate shall be made according to the arc of the side of the anti-collision wall.Most of the road signs produced by us are aluminum plate mark thickness: 1.5mm, 2mm, 2.5mm, and 3mm.Acid and alkali resistance, corrosion resistance, in the field through wind and rain, will not fade design description: can be made to order, or national standard special style.
