Description

Technical Field

[0001] The utility model relates to a corrosion-resistant aluminum alloy railing, belonging to the technical field of aluminum alloy railings. Background Art

[0002] An aluminum alloy railing is a kind of fence structure, and its main construction material is aluminum alloy. It is made through professional processing techniques and is widely used in the periphery of buildings, garden scenic areas, and various public places. Its core function is to provide clear space separation and area demarcation to ensure the orderliness of the space layout. This kind of railing, with the material characteristics of aluminum alloy, meets the basic usage requirements and plays an important role in different environments.

[0003] Since the aluminum alloy railing is directly exposed to the external environment, if its corrosion resistance is poor, it is easily damaged by corrosion factors such as the atmosphere, moisture, acid-base substances, etc., resulting in surface corrosion, oxidation, and even structural damage, greatly shortening its service life. If the structural strength of the aluminum alloy railing is weakened due to corrosion, it may cause the railing to loosen, deform, or even break, increasing the potential safety hazards during use, while destroying its original aesthetics, affecting the overall visual effect, and may cause a burden on the environment due to improper waste treatment.

[0004] Therefore, a corrosion-resistant aluminum alloy railing is proposed. Content of the Utility Model
