1. Stainless steel lamp pole, the way our country takes is to hot-dip galvanized surface treatment, hot-dip galvanized in line with international standards of product life can reach 15 years. Otherwise, it is far from being achieved. Mostly used in courtyards, residential areas, parks and other places.
2. Iron qualitative lamp post: our country is this kind of lamp post mostly, just the surface does spraying (brush lacquer or gush powder to handle), life is 3~5 years. The iron lamp pole used for general road lighting is more
3. Aluminum alloy lamp post: high strength aluminum alloy manufacturing, not only humanized to protect the safety of personnel, but also high strength, do not need any surface treatment has more than 50 years of corrosion resistance, and very beautiful. It looks more upscale.
China's current situation: China's current situation is the iron lamp pole market share, aluminum alloy lamp pole most exports to foreign countries. Especially in developed countries.
1. The road lamps with double arms are double single fire lamps. The motor vehicle lane lamps are 11.5 meters away from the ground, and the sidewalk lamps are 8.5 meters away from the ground. The two sides are arranged crosswise and the spacing is 50 meters. The street light source of the expressway is three-light 120WLED street light source, and the street light source of the sidewalk is Sanfengyuan 80WLED street light source. Highway generally uses 12m high bar lamp, single cantilever double cantilever, 400W high pressure sodium lamp.
2. Light pole material is made of high quality Q235A steel (the silicon content of steel is not higher than 0.04%, reference brand Shanghai Baosteel, Maanshan Iron and Steel, Shougang, etc.) bending conical rod, forming once, light pole is made of 4mm thick steel plate, lamp pole wall thickness does not include galvanized layer thickness. The main rod is conical rod, the upper diameter is about 85mm, the lower diameter is about 200mm. Steel pipe with a diameter of 60mm is adopted for the lifting rod, and the outer length of the lifting rod is 1.6m for the motorway, 1.2m for the pavement, and the wall thickness is 3mm.
3. Light pole surface smooth, shall not have any cracks, leakage welding, continuous porosity, edge bite, inequality phenomenon. The straight line error of the center line of the lamp pole shall not exceed 0.02% of the length of the rod. The appearance of the rod body shall have no uneven marks and the appearance of the lamp pole shall have no obvious defects.
4. The welding mode of lamp pole is automatic subarc welding and ultrasonic flaw detection, which can meet the requirements of GBl1345 ⅱ standard. Lamp post sleeve is fixed by threading nail and top wire.
5. The lamp pole adopts hot-dip galvanized anticorrosive treatment, zinc layer is not less than 75 microns, the surface has practical smooth, the color is basically the same, after the hammer test does not peel, not peeling, galvanized life is not less than 20 years.
6. Lamp post spraying should be made of high-quality outdoor pure polyester plastic powder, color to be agreed, smooth surface, stable quality of plastic layer, do not fade, do not fall off, strong adhesion, strong uv resistance, service life should not be less than 20 years, thickness ≥80um, in line with ASTMD339-83 standard.
