Sigama post

Highway guardrail sigma post is the best choice for secure highway and road applications. They are engineered and manufactured from the best quality materials to ensure top performance, resistance to corrosion and long lasting durability. The sigma guardrail post, also known as a "crash post" or "W-Beam", is designed to absorb and redirect vehicle impact energy and mitigate human injury in roadside protection systems. It also works to physically separate vehicles from potential sources of danger, such as deep ditches, trees, and utility poles.

The robust sigma post design is engineered to meet the American Association of State Highway and Transportation Officials (AASHTO) standards. This standard requires guardrail systems to have a minimum post spacing of 24 inches and a maximum post spacing of 72 inches. The posts are also designed to withstand a vehicle impact of up to 120 kmph (75 mph). The tremendous strength of the posts ensures that the guardrail is able to absorb a high amount of impact energy during a crash.

The sigma post is designed for long-term durability, with no regular maintenance required. As a result, it can provide effective roadside protection for years to come. When it comes to installation, the sigma post can be set in either ground or concrete and comes with pre-drilled holes for the guardrail connection. This makes installation quicker and easier.
