公路护栏网常常采用直径48mm的圆形钢管立柱进行安装固定，而铁路护栏网一般采用水泥构件作为立柱。即便同样是钢管立柱，铁路上采用的立柱壁厚也要相对厚些，一般在2.0左右，公路上则多为1.0左右。
2. The column is different. The 48 mm diameter circular steel pipe column is often used for the installation and fixation of highway guardrail, while the cement component is generally used as the column for railway guardrail. Even if it is the same steel pipe column, the wall thickness of the column used on the railway should be relatively thick, generally around 2.0, while on the highway it is mostly about 1.0.
3、质量不同。同样是框架护栏网，公路和铁路上使用的却是不同，一般铁路上财大气粗，用的框架护栏网比较重，质量也就要好一些，每套的价格大概在200元左右。反观公路上使用的框架护栏网，质量比较轻薄，价格相对也便宜，75元左右的价格就能购买。可见同是框架护栏网，但是质量却是相差甚远。
3. Different quality. It's the same frame fence, but it's different between the highway and the railway. Generally, the railway has a lot of money. The frame fence used is heavier and the quality is better. The price of each set is about 200 yuan. On the contrary, the quality of the frame fence used on the highway is relatively light and the price is relatively cheap. It can be purchased at a price of about 75 yuan. It can be seen that the same is the frame fence, but the quality is quite different.
4、种类不同。通常公路护栏网是指高速公路护栏网，高速公路护栏网经常使用的就三种：双边护栏网、框架护栏网、高速公路防眩网，且前面两网的顶部一般都带有30度的角度折弯。铁路护栏网通常选用框架护栏网作为防护产品，偶尔也使用三角折弯护栏网或是荷兰网、铁艺护栏网等，不过应用很少，也不普遍，而且多数情况下顶部没有30度的折弯。
4. Different types. Generally, highway guardrail net refers to highway guardrail net. There are three kinds of highway guardrail net often used: bilateral guardrail net, frame guardrail net and highway anti glare net. The top of the two kinds of guardrail nets in front generally has an angle bending of 30 degrees. The railway guardrail net usually uses frame guardrail net as the protection product, and occasionally uses triangular bent guardrail net or Dutch net, iron guardrail net, etc., but the application is rare and not common, and in most cases, there is no 30 degree bending at the top
