The sigma post as a support for the crash barrier and usually determines the performance of the guardrail during the collision. Proper installation of the sigma post will maximize the performance of the guardrail. The guardrail post has a long service life and the surface is usually hot-dip galvanized or spray-coated to provide rust and corrosion resistance.
Choosing the right guardrail post will have a strong ability to absorb collision energy of motorway barriers, and can be coordinated with the road line shape and various facilities. The sigma post can be installed and used on a small radius curve in motorway barriers, the connection is simple and convenient, and the damage is easy to replace.
