The materials of street lamps are rich and diverse, mainly including metal materials, glass materials, plastic materials and composite materials, etc. The following is a detailed introduction

- "Metal material

- ** Steel material ** : The iron street lamp poles in the steel material are generally made by rolling high-quality Q235 steel, and after hot-dip galvanizing treatment and plastic spraying, they can remain rust-free for 30 years. They are hard and have high strength, capable of withstands considerable external forces and pressure, and have relatively low costs, making them suitable for large-scale application. However, they are heavy and not easy to install and move.

- ** Aluminum alloy material ** : Made of high-strength aluminum alloy, it has over 50 years of corrosion resistance without any surface treatment. It is of high strength, light weight, easy to transport and install. The surface can undergo various coating treatments to enhance the aesthetic appeal and can also well adapt to environments such as coastal cities.

- ** Stainless steel material ** : It has excellent corrosion resistance, is not prone to rust, can be used for a long time in harsh environments, has relatively high mechanical strength, and has a relatively beautiful and clean appearance, but the cost is relatively high.

- "Glass material"

- ** Ordinary glass ** It features high transparency and soft light, which can make the light emitted by street lamps scatter more evenly, creating a comfortable lighting environment. It has various shapes and can be made into lampshades of different shapes and colors, suitable for decorative occasions such as parks and squares. However, it is fragile, has relatively low safety, and is relatively heavy, thus having certain limitations in its application range.

- ** Tempered glass ** : It has a much higher strength than ordinary glass, good impact resistance, and is not easy to break. Even if it breaks, it will form obtuse Angle particles, reducing the harm to the human body. It has good thermal stability and can withstand large temperature changes without cracking. It is often used in street lamp covers with high safety requirements.

- "Plastic material

- **ABS material ** : It features excellent impact resistance, high-temperature resistance and corrosion resistance. It is easy to process and form, can be made into various complex shapes, has a high surface finish, an attractive appearance, and a relatively low price. It is widely used in the production of street lamp shells for urban roads, residential areas and other places.

- **PC material ** : It has high transparency, comparable to glass, and extremely strong impact resistance, effectively resisting external force impacts. It also has good weather resistance and UV resistance, and is not prone to aging or discoloration when exposed outdoors for a long time. However, its cost is relatively high.

- **PVC material ** : It has good corrosion resistance and insulation, low cost, light weight, and is easy to process. It can be formed through various processes such as injection molding and extrusion. However, it has poor heat resistance and is prone to deformation in high-temperature environments. Its mechanical strength is relatively low.

- "Composite materials

- ** Aluminum-plastic composite material ** : It is made by combining aluminum alloy and plastic materials, integrating the advantages of both. It features light weight, corrosion resistance, UV resistance, etc. It has a long service life in outdoor environments, an attractive appearance, and can be designed in various colors and shapes as needed.

- ** FRP Composite material ** : That is, glass fiber reinforced plastic (FRP), with strength comparable to that of high-grade alloy steel, low density and light weight, being 1/4 to 1/5 of carbon steel. For lamp poles of the same specification, its weight is about 1/3 of that of steel poles. It has good insulation performance and will not cause electric shock accidents due to leakage during use. Its surface is very smooth and more aesthetically pleasing than ordinary steel poles.
