The power steel pipe is a new type of power line pole and tower, which has the advantages of small area, beautiful appearance, high strength and easy installation.

 

It is usually made of polygonal steel pipe, round steel pipe and other steel, using hot dip galvanized or hot spray zinc (and zinc alloy) coating anti corrosion treatment. It is mainly used for the erection of power lines and is an alternative to traditional cement poles.

 

The power steel pipe is a new type of power line tower, suitable for various environments and occasions. Its application helps to improve the safety and reliability of power lines, while also decorating urban landscapes.The power steel pipe has less impact on the environment during use.

 

On the one hand, the service life of the power steel pipe pole is long, which can reduce the waste of traditional wood poles, reduce the demand for wood, and help protect forest resources. On the other hand, the power steel pipe rod is treated with anti-corrosion during the production process, which can reduce the possibility of waste caused by metal corrosion, and the impact on the environment is relatively small
