Development history of aluminum guardrails

Colored aluminum alloy guardrails originated in European and American countries. They were widely used and industry standards were established as early as the 1970s. However, the use of colored aluminum alloy guardrails in China is still in its infancy. Due to the unfamiliarity of consumers with colored aluminum alloy guardrails, they do not recognize the essential perfection of colored aluminum alloy guardrails. Therefore, from the design unit to the user unit, they still follow the route of traditional wrought iron guardrails, cast iron guardrails, plastic steel guardrails, wooden guardrails, and inferior stainless steel guardrails. In daily life, we can see the adverse phenomena of brittle, rotten guardrails, continuous rust stains, and yellow robes everywhere, which seriously pollute the construction of civilized cities and constantly threaten people's health and the safety of life and property. Therefore, the repeated dismantling and replacement of guardrails is a common problem. The phenomenon of investment is very frequent. For example, when consumers buy a new house and decorate it, the guardrails look either rusty or cold. According to incomplete statistics, more than 85% of homeowners replace or cut off guardrails during new house decoration. Urban road isolation guardrails have also been replaced every few years, resulting in repeated financial investments. With the rapid development of the national economy and the needs of people's lives, the upgrading of guardrails is imperative and has broad development prospects.
