    现在随着经济的发展，国家对高速公路周边的安全越来越重视，但是公路铁丝网护栏使用寿命相对较短。造成这些铁丝护栏网损害的原因有哪些呢？
一、是铁丝网护栏本身的质量问题，随着铁丝网护栏的市场也随之不断扩大，市场大了，铁丝网护栏的生产厂家多了，难免生产出来的铁丝护栏网质量各不相同，厂家在生产的时候工艺技术达不到一定的标准。如果使用了这样的防护产品，本来使用年限应该在十几年的，可能在三四年之内就会生锈、破损，大大缩短了防护栏的使用期限。
二、根据当地环境的不同，高速公路两侧的围栏受影响的程度也会不同。比如在污染严重的地区，还有有酸雨的地区，铁丝护栏网还不到使用年限质量就大打折扣。
三、就是人为因素了。有些不法分子偷盗、毁坏公路护栏网，至使他人安全受到严重的威胁。这已经属于盗窃使用中的交通设施罪，已经构成犯罪。
