路灯灯杆是路灯系统中的“支架”，主要起“承载”作用，灯杆的质量决定了路灯的整体质量和耐用性。

Street lamp pole is the "support" in the street lamp system, which mainly plays the role of "bearing". The quality of the lamp pole determines the overall quality and durability of the street lamp.

那么路灯灯杆为什么要用Q235热镀锌板卷？

So why should the street lamp pole use Q235 hot plated galvanized coil?

因为路灯长期处于户外环境，为了防止灯杆路灯杆不容易被腐蚀。镀锌板卷具有防腐蚀作用，所以路灯灯杆用镀锌板卷，常见的镀锌板卷有冷镀锌和热镀锌。

Because the street lamp is in the outdoor environment for a long time, in order to prevent the lamp pole is not easy to be corroded.Galvanized plate coil has anti-corrosion effect, so the street lamp lamp pole with galvanized plate coil, the common galvanized plate coil has cold galvanized and hot galvanized.

冷镀锌外表比较光滑、明亮，采用彩色钝化工艺的电镀层也黄绿色为主色，呈七彩。采用白色钝化工艺的电镀层呈青白色或白色呈绿光，白色钝化工艺的镀层与阳光呈一定角度下略显七彩。在复杂工件的角棱部位容易产生“电烧”而成灰暗，该部位锌层较厚。在阴角部位易形成电流死角而产生欠电流灰暗区，该区域锌层较薄。工件整体无锌瘤、结块等现象。

Cold galvanized appearance is smooth and bright, the electroplating layer of color passivation process is also yellow-green as the main color, colorful.The electroplating layer of white passivation process is green white or white green light, and the plating layer of white passivation process is slightly colorful at a certain Angle.In the corners of the complex workpiece is easy to produce "electric burning" and gray, where the zinc layer is thick.In the negative Angle part, it is easy to form a current dead corner and produce an undercurrent gray area, where the zinc layer is thin.The whole workpiece without zinc tumor, lumps and other phenomena.

热镀锌外观较电镀锌稍微粗糙，呈银白色，外观容易产生工艺水纹和少许滴瘤，尤其是在工件的一端较为明显。但热镀锌的锌层比电镀锌厚几十倍，防腐蚀性能是冷镀锌的几十倍。

The appearance of hot galvanized is slightly rough than that of galvanized, silver white, the appearance is easy to produce process water lines and a little drip, especially at one end of the workpiece.However, the zinc layer of hot galvanizing is dozens of times thicker than electrogalvanizing, and the corrosion resistance is dozens of times that of cold galvanizing.

路灯杆为了保证其质量可靠性、耐用性，所选择的钢材主要是Q235钢，Q235钢所具有的良好的延展性和刚性是灯杆生产要求中最好的。Q235钢虽然有良好的延展性和刚性，但还是要进行表面热镀锌喷塑防腐蚀处理。热浸镀锌确保灯杆具有良好的耐腐蚀性，不易腐蚀，灯杆寿命可达15年。热镀锌喷塑均匀地将塑粉喷洒在灯杆上，并在高温下均匀地将塑粉附着在灯杆上，以确保灯杆的颜色不会因长时间而褪色。

In order to ensure its quality, reliability and durability, the selected steel is mainly Q235 steel, Q235 steel has good ductility and rigidity is the best production requirements of the lamp rod.Although Q235 steel has good ductility and rigidity, but still to surface hot galvanized plastic anti-corrosion treatment.Hot dip galvanizing ensures that the lamp rod has good corrosion resistance, not easy to corrosion, lamp rod life up to 15 years.Hot dip galvanized spray spray the plastic powder evenly on the lamp pole and attach the plastic powder evenly to the lamp pole at high temperature to ensure that the color of the lamp rod will not fade for a long time.
