As an important carrier of urban lighting systems, street light poles' material selection and processing technology are directly related to product performance, lifespan, and urban landscape effects. Currently, street light pole materials are mainly divided into three categories: iron, stainless steel, and aluminum alloy. Among them, iron poles still dominate the market, particularly Q235B high-quality steel, which is widely used in various road environments due to its high strength, moderate cost, and excellent processing performance.
With a diameter-to-thickness ratio of 90 or 1:100, the cross-section can be circular, hexagonal, or octagonal, which not only improves wind resistance but also enhances overall aesthetics. The wall thickness typically ranges from 2.5mm to 6mm, and is differentially designed based on the pole height and wind pressure requirements of the installation area, ensuring structural safety and reliability.
In terms of processing technology, welding quality is the key link. The welding of each section of the lamp pole must strictly follow national standards, with uniform welds and no defects such as pores or slag inclusions, to ensure overall strength and durability. After welding and forming, surface treatment technology is particularly crucial, mainly using hot-dip galvanizing and spray plastic coating for anti-rust and corrosion resistance. The hot-dip galvanized zinc layer thickness is controlled at 65-90 microns, which can effectively resist atmospheric corrosion and extend the service life to more than 15 years; the outer layer is then treated with spray plastic coating, which not only enhances corrosion resistance but also provides a variety of color options to improve urban landscape coordination.
Moreover, the spray plastic coating should have a smooth surface, free from sagging, cracks, with strong adhesion, excellent weather resistance, and adaptability to various climatic conditions. Some high-end products have introduced advanced technologies such as electrostatic spraying and fluorocarbon spraying to further enhance the protection level and visual texture.
In summary, the material and processing technology of street lamp poles are the core factors determining their performance and lifespan. In the future, with the development of new materials and intelligent manufacturing technologies, street lamp poles will evolve towards lightweight, intelligent, and eco-friendly directions. Against the background of urban infrastructure upgrades, optimizing material selection, improving processing precision, and enhancing anti-corrosion levels will become the continuous professional goals of the industry.
