[0002] Beach guardrails need to be exposed to the seaside for a long time and are subject to the erosion of sea breeze and seawater. Therefore, beach guardrails need to withstand the test of harsh environments. However, most of the existing beach guardrails are made of metal or gravel structures, which are prone to rust or weathering in harsh environments and cannot meet the requirements.

[0003] Fiber Reinforced Plastics, commonly known as FRP (Fiber Reinforced Plastics), are fiber reinforced composite plastics. Due to the addition of high-performance fibers, FRP materials have good strength and modulus, can withstand greater loads and deformations, and have excellent mechanical properties. Moreover, fiber reinforced plastics can be used for a long time in harsh environments and have excellent corrosion resistance. They can also be molded through molds to produce various complex structures, with excellent plasticity. However, it is still rare to use FRP materials as beach guardrails. In view of the above deficiencies, there is a need for a beach anti-corrosion and wear-resistant FRP safety guardrail and an installation method thereof, which are not only convenient to install and firmly fixed, but also have excellent corrosion resistance and mechanical properties.
