The importance of traffic light signal bar hot galvanizing

we all know that the signal light pole is galvanized through two process: galvanized and spraying. The two most important is in the process of galvanizing process. Now, some signal light pole manufacturers have adjusted the antirust technology to control the cost and cancel galvanizing technology. After spraying the signal light pole, can't see from the outside pole is galvanized. It will make a lot of people confused. Let's make a brief introduction of the role and importance of light galvanized process. Galvanized before must remove light pole by sulfuric acid process, make the light pole into hot galvanized trough without rust, after reaching a certain temperature and time of hot dip galvanized processing. From here we can see rust removal process is critical. If there is no clear signal lamp itself rusty spot, best galvanized is going to be a drop of the barrels, because the rusty spot will slowly corrosion under the zinc layer, until the top of the galvanized layer. We are not the key to galvanized, than rust removal is the key. That is to say, everyone should know the truth. Yes, that is to say, no galvanized signal light pole will never be used. Say this type of street light can't use an exaggeration. If it does not fear the use of ugly lamp light crossroads, it may not be a problem. Injected directly into the black did not respond in a short time, but can ensure the whole lamp can produce irregular explosion in a year. It is becoming more and more serious, until the two poles is full of white, black and yellow. The reason is very simple. There are both oil and rust galvanized signal lamp itself. Spray can override it, but can not eliminate it. At this time, the rust corrosion off naturally. As long as the coating layer is broken, and will accelerate the expansion of the stem all rusty spot. Identify the galvanized paint signal lamp is very simple. Find a small place, with a blunt gently scrub. Only remove the spray layer. That's no problem, if the color is silver. If it is black, and come back directly, don't use it. All the same. I would rather spend more money to buy a good, also do not want to buy cheap. The quality must be good enough.
