F、 Core advantages of hot-dip galvanized street Light Poles
1. Unparalleled anti-corrosion performance:
Physical barrier: The dense zinc layer isolates the steel from contact with air and moisture.
Cathodic protection: When the zinc layer is partially damaged, zinc will act as a sacrificial anode to preferentially corrode, protecting the exposed steel substrate from corrosion (self-healing ability).
Strong weather resistance: It can effectively resist erosion from different atmospheric environments such as urban, industrial, and marine environments (especially those containing salt and acid rain).
Good wear resistance: The zinc layer has a certain hardness and can resist slight scratches during transportation and installation.
2. Long service life:
Under standard atmospheric conditions, the design service life of hot-dip galvanized Lamp Poles is usually required to be over 20 years, but in actual use, many can reach 30 years or even longer. This significantly reduces the frequency and cost of replacing and maintaining Street Light Pole.
3. Excellent adhesion and toughness:
The metallurgical bonding layer integrates the zinc layer with the steel substrate, making it less likely to peel off due to impact or bending during processing (such as drilling, zinc replenishment after welding), transportation, installation, or use.
4. Overall protection: The inner and outer surfaces (including the inner wall of the lamp tube), corners, and gaps of the Light Pole can be covered with zinc solution, providing comprehensive protection. This is something that spraying technology cannot fully achieve.
5. Lower long-term maintenance costs: Although the initial investment is higher than painting or cold galvanizing, its ultra long maintenance free period greatly reduces the cost of subsequent anti-corrosion treatment (such as painting and refurbishment) and labor costs, making it highly advantageous in terms of full life cycle cost.
6. Good economy: Considering its long service life and extremely low maintenance requirements, hot-dip galvanizing is a cost-effective anti-corrosion solution.
7. Environmental friendliness: Zinc is a naturally occurring element, and the hot-dip galvanizing process is relatively controllable. Longevity reduces resource consumption and waste generation. The discarded zinc layer can be recycled and reused.
