Light pole manufacturers for street light poles Technical requirements: 1. The two-way road street light is double-selected single fire light, the motorway light fixture is 12 meters away from the ground, the sidewalk light fixture is 8.5 meters away from the ground, and the two sides are arranged at a distance of 50 meters. The expressway road light source is a three-light source 120W LED street light, and the pedestrian road light source is a Sanfengyuan 80W LED street light. The road is generally 12m high pole light, the cantilever has a single pick and double pick, 400W high pressure sodium lamp.

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, Maanshan Iron and Steel, Shougang, etc.) to form a tapered rod, one time forming, lamp The rod is made of 4mm thick steel plate, and the wall thickness of the pole does not include the thickness of the galvanized layer. The main pole of the pole is a tapered rod with a diameter of about 85 mm and a diameter of about 200 mm. The poles are all made of 60mm diameter steel pipe, the outer motorway is 1.6 meters, the sidewalk is 1.2 meters, and the wall thickness is 3mm.

3. The surface of the pole is smooth, and there must be no cracking, missing welding, continuous venting, undercutting or inequality. The linear error of the center line of the pole is not more than 0.02% of the length of the rod. The appearance of the rod has no unevenness and no trace, and the appearance of the pole has no obvious defects.

4. The welding method of the lamp post is automatic sub-arc welding, ultrasonic flaw detection, and the welding standard GBl1345II. The socket of the pole is fixed by nailing and top wire.

5. The lamp post is treated with hot-dip galvanizing and anti-corrosion treatment. The zinc layer is not less than 75 microns. The surface is practical and smooth, the color is basically the same. After the hammering test, the skin is not peeled off, no peeling, galvanizing life. Not less than 20 years.

6, the light pole manufacturer's light rod spray should use high quality outdoor pure polyester plastic powder, the color is to be agreed, the surface is smooth and smooth, the plastic layer quality is stable, no fading, no falling off, strong adhesion, Resistant to strong ultraviolet rays, the service life should not be less than 20 years, thickness ≥ 80um, in line with ASTM D339-83 standard.
