Aluminum alloy guardrails use high-strength aluminum alloy as the main material, which is extruded into standardized profiles and then assembled into a complete structure. Its core advantages are:
Corrosion resistance: A natural oxide film forms on the aluminum alloy surface, resisting corrosion from humid, acidic, and alkaline environments, extending its service life;
Lightweight: Its density is only 1/3 that of steel, facilitating transportation and installation while reducing the load on the supporting structure;
Diverse colors: Through anodizing or spraying processes, high-saturation colors such as red, yellow, and blue can be achieved to meet the warning needs of different scenarios.
Structurally, they typically consist of posts, horizontal bars, and vertical bars. Some models add reflective strips or warning signs to further enhance nighttime safety.
Compared to traditional metal railings, aluminum alloy exhibits superior corrosion resistance, lightweight design, and aesthetic appeal, making it suitable for various applications such as road separation, bridge protection, and park fencing.
