What is the general wall thickness of the lamp pole?

Street lamp pole wall thickness standard: the service life should not be less than 20 years, thickness ≥80um, in line with ASTMD339-83 standards.

Street lamp pole is divided into: high pole street lamp, street lamp, monitoring pole, new shaped tube street lamp, stainless steel landscape lamp, shaped landscape lamp, sculpture landscape lamp, garden lamp, cast aluminum garden lamp, cast iron garden lamp, stainless steel garden lamp, shaped garden lamp, new shaped tube garden lamp, iron lamp, spotlight, lawn lamp, stainless steel lawn lamp, outdoor wall lamp, fireworks lamp, etc.

First, the type of street lamp pole

 

1, stainless steel light pole, China's way is to carry out hot galvanizing surface treatment, hot galvanizing in line with international standards of product life can reach 15 years. Otherwise, it is far from being achieved. Most of them are used in courtyards, residential areas, parks and other places.

 

2, iron light pole: most of our country is this kind of light pole, only the surface to do a spray (paint or powder treatment), the life is 3 to 5 years. General road lighting uses more iron light poles

 

3, aluminum alloy light pole: high-strength aluminum alloy manufacturing, not only humanized to protect the safety of personnel, but also high strength, do not need any surface treatment also has more than 50 years of corrosion resistance, and very beautiful. It looks more upscale.

 

4, China's current status: China's current status is that iron light poles account for most of the market share, aluminum alloy light poles are mostly exported to foreign countries. Especially developed countries.

 

Second, street lamp pole technical requirements

 

1, the double-arm road street lamp is a double-pick single fire lamp, the motor vehicle road lamp is 11.5 meters from the ground, the sidewalk lamp is 8.5 meters from the ground, the bilateral cross arrangement, the spacing is 50 meters. The light source of the fast lane street lamp is the three-light source 120WLED street lamp, and the sidewalk street lamp is the three-Fengyuan 80WLED street lamp. On the road, 12m high-pole lights are generally used, and the cantilever has single and double cantilevers, and 400W high-pressure sodium lamps.

 

2, the light pole material is made of high-quality Q235A steel (the silicon content of steel is not higher than 0.04%, refer to the brand Shanghai Baosteel, Masteel, Shougang, etc.) bending shaped cone rod, a molding, the light pole is made of 4mm thick steel plate, the wall thickness of the light pole does not include the thickness of galvanized layer. The main rod of the lamp pole is a conical rod, the diameter of the upper mouth is about 85mm, and the diameter of the lower mouth is about 200mm. The lifting rod is made of 60mm diameter steel pipe, the lifting length is 1.6 meters for the motor road, 1.2 meters for the sidewalk, and the wall thickness is 3mm.

 

3, the light pole surface is smooth, there must be no cracking, leakage welding, continuous porosity, edge bite, inequality phenomenon. The linear error of the center line of the light pole does not exceed 0.02% of the length of the pole, the appearance of the pole body has no bumps and marks, and the appearance of the light pole has no obvious defects.

 

4, the lamp pole welding mode is automatic sub-arc welding, ultrasonic inspection, welding GBl1345 II standard requirements. The socket of the light pole is fixed with nails and top wire.

 

5, the lamp pole adopts hot-dip galvanizing anticorrosive treatment, the zinc layer is not less than 75 microns, the surface is practical and smooth, the color is basically the same, the skin is not peeling after the hammer test, and the galvanizing life is not less than 20 years.

 

6, the pole should be sprayed with high-quality outdoor pure polyester plastic powder, color to be agreed, the surface is smooth and smooth, the quality of the plastic layer is stable, does not fade, does not fall off, strong adhesion, strong ultraviolet resistance, the service life should not be less than 20 years, thickness ≥80um, in line with ASTMD339-83 standards.
