Colored aluminum alloy railings originated in Europe and America, where they were widely used as early as the 1970s and industry standards were established. In China, however, the use of colored aluminum alloy railings is still in its infancy. Because many consumers are unfamiliar with colored aluminum alloy railings and do not recognize their inherent advantages, both design and user units are still following the traditional path of using wrought iron, cast iron, PVC, wooden, and inferior stainless steel railings. As a result, we see railings everywhere that are brittle, rotten, covered in rust, and yellowed, seriously polluting urban construction and constantly threatening people's health, lives, and property. Therefore, the phenomenon of repeated investment in railing removal and replacement is very frequent.
For example, when consumers buy new houses and renovate, the railings often appear rusty or cold. According to incomplete statistics, more than 85% of homeowners replace or cut off their railings when renovating their new homes. Urban road guardrails are also being replaced every few years, resulting in repeated government investment. With the rapid development of the national economy and the increasing demands of people's lives, the upgrading of guardrails is inevitable and has broad development prospects.
