Signal light pole lamp material is introduced

Commonly used is high-quality steel factory plate manufacturing led lamps and lanterns, hot dip galvanized processing, polishing again after coating. This kind of product is very popular, but it can also be due to the price is expensive, and selects the cold-rolled strip steel Q235 and Q195, this does not recommend the government use. Although hot dip galvanized anti-corrosion, but also



the commonly used is high quality steel factory plate manufacturing led lamps and lanterns, hot dip galvanized 【 Hot dip galvanized, 镀锌) Also called hot dipping zinc and hot galvanizing, is an effective way of metal corrosion, mainly used for metal structure industry facilities. 】 After processing, polishing again after coating. This kind of product is very popular, but it can also be due to the price is expensive, and selection of cold rolled strip steel 【 Cold-rolled strip steel refers to hot rolled strip steel and steel plate as raw material, at room temperature by the cold mill rolling into a strip and sheet. 】 Q235【 Also known as A3 steel Q235 plain carbon structural steel. 】 And Q195 【 Q195 is a kind of carbon structural steel, yield strength of 195 mpa. 】 , this does not recommend the government use. Although hot dip galvanized anti-corrosion, but also can present problems of internal and external wall rust and scars, in daily protection, using ultrasonic and magnetic particle inspection Using the workpiece defect magnetic powder flaw detection of leakage magnetic field and the interaction of magnetic powder, it USES the steel surface and near surface defects ( Such as cracks, slag inclusion, hair lines, etc. ) Permeability and steel permeability difference, these materials after magnetization of the magnetic field discontinuity distortion will occur, forming part of the magnetic flux leak occurs on the surface of workpiece leakage magnetic field, so as to attract the magnetic powder form of defect magnetic powder - — Magnetic mark, under the condition of appropriate lighting, showing defects location and shape, observation and interpretation on the accumulation of these magnetic powder and magnetic powder flaw detection is realized. 】 To exploration and high lamp' Light, generally refers to more than 15 meters steel conical light pole and high-power modular fixtures are composed of new type of lighting. 】 Surface side, is now commonly used way of cleaning. 【 The above articles released by traffic signal lamp post sorting 】
