The materials of street lamps are mainly divided into the following types, which are selected according to the application scenarios and performance requirements:
Iron lamp pole (Q235 steel)
The most common material, hot-dip galvanizing anti-corrosion treatment, with a service life of more than 15 years.
The cost is low, but regular maintenance is required to prevent rust, and it is widely used in ordinary road lighting.
Aluminum alloy lamp pole
Lightweight and corrosion-resistant, it can be used for more than 50 years without complex surface treatment.
It has high aesthetics and is mostly used for landscape lighting or exported to developed countries.
Stainless steel lamp pole
Strong chemical resistance, suitable for high humidity or corrosive environments (such as coastal areas).
It has a high cost and is commonly used in places such as courtyards and squares that require long-term durability.
Other materials
Fiberglass (FRP): Corrosion-resistant but brittle, it is rarely used.
Plastic: Mostly used for lamp heads or decorative parts, light but low strength.
Concrete lamp poles: They have been basically eliminated due to their bulkiness and safety hazards.
