Material properties of galvanized steel lamp posts:

1.High strength: The main body of the galvanized steel lamp pole is crafted from high-quality steel, boasting high strength and rigidity. It can bear the weight of the lamp and resist potential external forces like wind and seismic forces, ensuring the stability and safety of the lamp pole under various environmental conditions.
2.Corrosion resistance: Via the hot-dip galvanizing process, a thick zinc coating is formed on the steel surface. This zinc coating can effectively block air and moisture, preventing the steel from rusting and corroding. Even in severe outdoor environments—such as humid coastal areas or heavily polluted industrial zones—it can maintain excellent corrosion resistance for an extended period, prolonging the service life of the lamp pole.

The manufacturing process of hot-dip galvanized lamp posts:

1.Cutting and blanking: In accordance with design specifications, steel is sliced to specific lengths and dimensions to produce the raw blanks for each component of the lamp post.
2.Forming operations: Through methods like bending and rolling, the cut steel is shaped into the desired forms of lamp posts, such as circular or polygonal structures. For lamp posts with unique shapes or specific requirements, additional processes like welding and polishing may be required to ensure their appearance and dimensional precision.
3.Hot-dip galvanizing treatment: The formed lamp posts undergo surface pre-treatment to eliminate contaminants like oil and rust, then are submerged in molten zinc for hot-dip galvanizing. During this process, the zinc liquid forms a uniform, dense zinc coating on the lamp post surface, with a thickness typically ranging from several tens to hundreds of microns—specifically determined by the usage environment and design criteria.
4.Surface finishing: After hot-dip galvanizing, the lamp post surface generally exhibits a silver-gray metallic sheen. To cater to varied aesthetic needs and further boost corrosion resistance, surface spraying is sometimes applied—such as coating with paints or powder coatings in various colors—endowing the lamp posts with enhanced decorative appeal and weather resistance.

Maintenance and care:

1.Cutting and blanking: Following design requirements, steel is cut into specific lengths and sizes to create the raw materials for each part of the lamp post.
2.Shaping processes: Using techniques such as bending and rolling, the cut steel is formed into the intended shapes of lamp posts, including circular or polygonal ones. For lamp posts with special shapes or particular demands, extra procedures like welding and buffing may be needed to guarantee their look and dimensional accuracy.
3.Hot-dip galvanizing treatment: The shaped lamp posts go through surface pre-processing to get rid of impurities like oil and rust, then are dipped into molten zinc for hot-dip galvanizing. In this process, the zinc liquid forms a uniform and tight zinc layer on the lamp post's surface, with a thickness usually ranging from tens to hundreds of microns—the exact thickness depends on the usage environment and design specs.
4.Surface handling: After hot-dip galvanizing, the lamp post's surface usually has a silver-gray metallic shine. To meet different aesthetic needs and further improve corrosion resistance, surface spraying is sometimes done on the lamp posts, such as applying paints or powder coatings of various colors, which gives the lamp posts better decorative features and weather resistance.
