The guardrail is widely used in public works such as municipal engineering, transportation, community, port, airport, warehousing, garden, green space, etc. It can be used for the division of different use areas, or a security facility specially designed for personal safety considerations. The guardrails generally need to be assembled on site by the installation workers. For this reason, the convenience of the installation of the guardrails is particularly important, and since the guardrails are generally used in open-air public places, it is inevitable to withstand external forces from all parties during use. The support strength of the guardrail cannot be ignored.
