Xi'an traffic signage production and processing, how is a city's traffic language developed?

Walking on the streets of Xi'an, from the ancient city walls to the new high-tech zones, you will always see various traffic signs. They either guide the direction, warn safety, or regulate order. They stand silently and constitute the city's clear and orderly "traffic language". But have you ever thought about the rigorous and even "serious" production and processing process that these seemingly ordinary signs went through from design to final erection on the roadside? Let's put aside those lofty theories and talk about the real methods in the production and processing of local traffic signs in Xi'an.

You have to know that traffic signs are not ordinary billboards. Behind them are the national standards (GB) and a series of industry standards. In Xi'an, the first thing a regular manufacturer does after receiving a job is not to open the machine, but to "pick out the standards", such as size, shape, color (especially the specific blue, green, red and yellow). Should the reflective film be engineering grade, super engineering grade or diamond grade? There are strict regulations, and even the slightest difference may affect the night recognition effect. This is no joke. Some small factories have cheap pictures, use inferior reflective films or have inaccurate colors. They look similar during the day but become "blind" at night. This is not only a quality problem, but also a safety hazard. Reliable Xi'an manufacturers often start competing when materials are put into storage. Their seriousness is no less than that of making precision instruments.

The design process is becoming more and more demanding now. Xi'an is a very special city, with both a profound historical heritage and a modern urban context. On the signboards in some specific areas (such as around scenic spots and historical districts), in addition to ensuring accurate information and clear hierarchies, sometimes it is also necessary to consider the relationship with the city. For the coordination of style and appearance, although the main body must comply with national standards, in some auxiliary designs or signs in cultural landscape areas, small ideas such as Tang patterns and city wall elements can also be seen, giving the cold instructions a touch of Chang'an charm. This requires designers to not only understand the standards, but also understand the temperament of the city.

Next comes the core production and processing, which is not just simple cutting and printing. Taking the most common aluminum signage as an example, the plate must be cut, punched, and folded first. This work requires skilled craftsmen and precise equipment. The corners must be rounded and the dimensions must be precise. Otherwise, it will be troublesome if the holes are not aligned during installation. Surface treatment is the key. Grinding, cleaning, and drying must be done in one step, in order to make the substrate clean, so as to ensure that the subsequent film or spraying effect is strong.

The most technical aspect is the application of reflective film. This is a manual job and the environment must be clean and dust-free. ； The technique must be steady and there should be no bubbles or wrinkles. Large signs often need to be spliced. The processing of seams is particularly demanding and must be so smooth that it is almost invisible. Xi'an is hot in summer and cold in winter, and materials expand and contract with heat. Master craftsmen have to take this into consideration and leave a subtle margin when applying the film. The concentration of experienced workers when doing this work is like making handicrafts.

Printing or silk-screening pattern text is even more precise. There are strict regulations on the fonts, arrows, and numbers of traffic signs, and the thickness and spacing of strokes are all standardized. Nowadays, many manufacturers use computer lettering and automated printing, which are highly efficient and consistent. However, some special specifications or emergency filling still require the hand-made silk screen printing of master craftsmen. The thickness and uniformity of the ink depend entirely on the feel of the hand, and machines cannot really replace it.

Do you think installation is just a matter of driving a few screws? It’s not that simple. In Xi’an, when erecting a pole and installing a sign, you have to consider the position, height, and angle to ensure that the driver can clearly and timely identify it from a dynamic perspective. You also need to consider wind load, anti-theft, and anti-collision. The construction team often has to work at night when there are few cars and coordinate with the traffic police to ensure safety. It is very hard work. A sign stands there and has been exposed to the sun and rain for many years. To be stable, the solidity of the installation is crucial.

You see, a traffic sign on the streets of Xi'an, from the time it was just a drawing and an aluminum plate, has condensed the care of standards, design, materials, processes, and installation in all aspects. It is not just an industrial product, but more like a "guardian" of public safety and order in the city. Its production and processing process combines strict regulations and standards, constantly improving technology, and the simple ingenuity of local master craftsmen.

Next time you see those silently guiding signs on the streets of Xi'an, you may feel that they are not just cold metal and reflective films. Behind them is a set of rigorous systems and a group of people who silently contribute to the city's traffic safety. They use professionalism and meticulousness to forge the city's "traffic language", making it clear, accurate and reliable, and protecting everyone's travel safety. This may be the most real value of Xi'an's traffic sign production and processing industry.
