Are antique street lights prone to fading, cracking or corrosion after long-term outdoor use?

Factors affecting fading, cracking and corrosion
Antique street lights are important decorative elements of urban landscape and traditional cultural atmosphere, and are widely used in outdoor places such as parks, scenic spots, historical districts and cultural squares. Because they are exposed to the natural environment of wind, sun, rain and snow all year round, their weather resistance has gradually become an important consideration in purchase and maintenance. Whether fading, cracking and corrosion will occur after long-term use is also directly related to their aesthetics and service life.

Causes and control methods of surface fading
Antique street lights can present a classical appearance, usually relying on spraying imitation copper, imitation wood, imitation stone and other color effects. Long-term exposure to ultraviolet rays, high temperatures and acid rain environments may cause aging reactions in coating materials, causing the surface color to gradually lose its original gloss or depth, and even appear mottled. Especially in high sunlight or humid and hot environments, this process may be accelerated.
In order to slow down the fading, a specially treated anti-ultraviolet coating is generally used in the manufacturing process, or a transparent protective layer is added after painting to enhance surface stability. In addition, choosing a coating with a higher light resistance level is also a way to improve color retention. For users, regular cleaning of dust and pollutants and avoiding strong corrosive substances from contacting the coating can also help delay fading.

The cracking problem is related to material stability
The poles and lampshades of antique street lights are usually made of metal materials such as aluminum alloy, cast iron or stainless steel. Some products also use glass fiber reinforced materials as structural parts. When the temperature difference changes frequently or the material is damp and dried repeatedly, tiny cracks may appear on the surface of some materials, especially when the coating and the metal are not firmly bonded, cracking is more likely to occur.
Low-quality casting or inferior spraying process can also bury hidden dangers for cracking. If the metal cannot effectively release stress during the process of shrinking and expanding, it may also cause the paint layer to crack. Improving the density of raw materials and enhancing the adhesion between the surface and the substrate are the key to controlling cracking. When purchasing, users should pay attention to whether the product has been tested for thermal expansion and contraction cycles, and whether it has a certain degree of ductility and deformation resistance.

The risk of corrosion is closely related to the protection process
The humidity, pH and industrial pollution factors of the outdoor environment may accelerate the metal corrosion of antique street lights. Acid rain, water mist, salt spray and other factors are particularly likely to cause corrosion to metals that have not been properly treated on the surface, causing them to gradually rust or peel off, which not only affects the appearance, but also threatens the structural strength.
To improve corrosion resistance, manufacturers usually use multiple processes such as hot-dip galvanizing, plastic spraying, and electrostatic coating to treat the metal surface to form a dense protective film layer. Some products also add sealing rings or waterproof covers at key nodes to prevent water or moisture from entering the structure. Even so, when used in corrosive environments such as seaside or industrial areas, the protective layer should be checked regularly to see if it is intact. If the coating peels off, it should be repaired in time.

Antique street lights have taken into account the various challenges of the outdoor environment during design and manufacturing, but their long-term performance is still affected by factors such as the climate of the area of ​​use, maintenance frequency and installation specifications. If you can pay attention to the selection of craftsmanship and materials during the procurement stage, keep it clean during daily use, prevent human scratches, and inspect and maintain it on schedule, the risks of fading, cracking and corrosion on the surface can be effectively controlled, and the service life will be relatively extended. For places with high requirements for landscape aesthetics, it is recommended to use products with certain UV resistance and rust resistance certification, and choose matching protection treatment solutions according to the local climate environment. Through scientific selection and reasonable maintenance, antique street lights can retain their ancient charm and functional value for a longer time.
