Under normal circumstances, the separation distance of highway guardrail posts is between 2 and 4 meters. Under normal circumstances, a highway column with a spacing of 4 meters is combined with a highway guardrail baffle to form a highway guardrail. In the accident-prone areas, highway guardrail columns with a distance of 2 meters are usually selected to ensure the suitability of highway guardrail guards.

The gap between the highway column and the guardrail baffle. It is fastened with large screws, and some road sections may be fixed with anti-theft screws to prevent artificial disassembly damage.

When the installation method of expressway guardrail needs to be customized from cold bending equipment, its installation method and hole location are designed. There are different installation methods for different highway sections. This should be taken into consideration when customizing cold bending equipment.

The anti-impact level of highway guardrail is divided into A, B ~ SS level (a total of five levels). The grade starting with S is a guardrail baffle with a thickness of 4.0 to 6.0mm. It is usually used for highway guardrails on high-risk sections such as coastal highways and mountain highways.

The bending radius of the highway guardrail roll forming machine of the two-waveform guardrail can improve the overall aesthetics of the guardrail baffle and the anti-impact twisting strength. In the process of production equipment for cold-bending machinery of highway guardrails, a roll forming cold bending process is adopted to keep the guardrail in its curved arc shape with the most resilient shape, thereby ensuring its application in highway guardrail facilities To reduce the serious harm caused by vehicle accidents to the highest degree.
