1. Anti-corrosion process of street lamp poles: Please pay attention to whether the solar street light pole is hot-dip galvanized or cold-dip galvanized. The difference between hot-dip galvanizing and cold-dip galvanizing is the cutout. Hot-dip galvanizing still has a coating on the cut and cold-dip galvanizing on the cut. Uncoated. Half of the lamp head is 60 and the wall thickness is about 2.8. The lower end is height related and has a conic ratio and a wall thickness of about 4. The life of hot dip galvanized light poles is usually more than 20, while the life of cold dip galvanized light poles is more than 20. The life of a light pole is usually about 1 year.
2. Solar cells: Check whether the solar street light battery is a dedicated energy storage battery. Today, the street light market is uneven, and many small companies use ordinary power batteries, which greatly damages the service life of solar street lights.
