波形护栏的分类

Classification of wave barrier

波形梁护栏一般按设置地点和防撞等级来分类。

Wave beam barrier is generally set according to the location and collision level to classify.

按设置地点可以分为路侧护栏和中央分隔带护栏。

According to the location can be divided into the roadside guardrail and the median divider.

按防撞等级可分为A级和S级。S级护栏属于加强型，适用于路侧特别危险的路段使用，A级用于专用公路。

According to the collision avoidance rating can be divided into class A and S. The S level is enhanced barrier, suitable for use in the roadside especially dangerous road, a highway for special.

按防撞等级一般可分为A级和B级。A级护栏属于加强型，适用于路侧特别危险的路段使用，B级用于专用公路。

According to the level of collision avoidance can be divided into class A and B. A fence is enhanced, especially suitable for use in the roadside dangerous sections, B grade for special highway.

波形梁护栏产品介绍：常用路侧波形梁护栏按防撞等级可分为B、A、SB、SA、SS五级，高速公路防撞护栏是典型的冷弯型钢产品；二

W-beam guardrail products introduction: common roadside guardrail according to the level of anti can be divided into five class B, a, Sb and SA, SS, guardrail of highway is typical of cold-formed steel products; second
