High-Speed Guardrail Product Details
High-speed guardrail is a critical safety barrier designed for highways, expressways, bridges, ramps, and other high-speed traffic areas. It is mainly used to prevent vehicles from rushing out of the road, reduce accident severity, and protect drivers and passengers.
Our guardrail is manufactured from high-strength hot-dip galvanized steel through professional rolling forming, bending, and welding processes. The surface is treated with hot-dip galvanizing or plastic spraying, which provides excellent corrosion resistance, weather resistance, rust prevention, and long service life even in harsh outdoor environments.
With high structural strength and good impact absorption performance, the guardrail can effectively buffer impact force and guide vehicles back to normal driving direction. It features stable performance, simple construction, convenient installation and maintenance, and is widely used in highway construction, traffic safety engineering, municipal roads, and large-scale infrastructure projects.
All products comply with relevant national and international standards, with reliable quality and complete specifications to meet different engineering requirements.

Advantages of Roll Forming A Metal Part
There are several advantages of using roll forming for your projects:
- The roll forming process allows operations such as punching, notching, and welding to be performed in-line. Labor cost and time for secondary operations are reduced or eliminated, reducing part costs.
- Roll form tooling allows for a high degree of flexibility. A single set of roll form tools will make almost any length of the same cross-section. Multiple sets of tools for varying length parts are not required.
- It can provide better dimensional control than other competing metal forming processes.
- Repeatability is inherent in the process, allowing easier assembly of roll formed parts into your finished product, and minimizing problems due to “standard” tolerance build up.
- Roll forming is typically a higher speed process.
- Roll forming offers customers a superior surface finish. This makes roll forming an excellent option for decorative stainless steel parts or for parts requiring a finish such as anodizing or powder coating. Also, texture or pattern can be rolled into the surface during forming.
- Roll forming utilizes material more efficiently than other competing processes.
- Roll formed shapes can be developed with thinner walls than competing processes
Roll forming is a continuous process which converts sheet metal into an engineered shape using consecutive sets of mated rolls, each of which makes only incremental changes in the form. The sum of these small changes in form is a complex profile.
