The zinc steel guardrail of Tieyi guardrail factory is made of black pipe, hot-dip galvanizing after pickling, so the anti-corrosion effect has the anti-corrosion performance of power accessories. In order to reduce the cost, the zinc steel guardrail of many small factories is made of cold galvanized iron plate by high-frequency welding, and then made into iron guardrail by punching, cutting according to size, assembling and other processes.

如果想知道锌钢铁艺护栏的寿命，需要了解冷镀锌的特性，冷镀锌，质软而薄，相对于磷化和裸板的防锈效果要好很多，这也就是很多铁艺护栏厂家说的很久不生锈的道理，为了让锌钢护栏有更多的色彩，我们便在铁艺护栏的表面做喷涂，喷涂的质量直接导致锌钢护栏的防腐能力，如果喷涂做的相对较好的情况下，将对锌钢护栏的防腐，耐候性以及附着力将有很大的提升，那么，我们以什么为标准来衡量锌钢铁艺护栏的这些指标呢？

If you want to know the service life of zinc steel guardrail, you need to understand the characteristics of cold galvanizing. Cold galvanizing is soft and thin, which is much better than phosphating and bare board. This is the reason that many iron guardrail manufacturers say that it does not rust for a long time. In order to make zinc steel guardrail have more colors, we spray on the surface of iron guardrail, The quality of spraying directly leads to the anti-corrosion ability of zinc steel guardrail. If the spraying is relatively good, the anti-corrosion, weather resistance and adhesion of zinc steel guardrail will be greatly improved. So, what is our standard to measure these indexes of zinc steel guardrail?

1、切口位，在安装的时候锌钢护栏的切口位是个致命的大问题，如果锌钢护栏的切口位处理不当，将直接导致切口位短时间生锈，就是正常雨天过后，会从锌钢护栏的管里面流黄水出来，这样就到会降低锌钢护栏的使用寿命。

1. Notch position, when installing, the notch position of zinc steel guardrail is a fatal problem. If the notch position of zinc steel guardrail is not handled properly, it will directly cause the notch position to rust for a short time, that is, yellow water will flow out from the pipe of zinc steel guardrail after normal rainy days, which will reduce the service life of zinc steel guardrail.

2、就是锌钢护栏的喷涂附着力的测试，如果喷涂的附着力差了，不仅影响美观，而且还直接影响锌钢护栏的防腐能力，如果防腐能力较好，将对锌钢护栏的使用年限会延长一些，相对比传统的黑铁皮护栏使用年限少长4-5倍时间，如果锌钢护栏的防腐能力不好，将会出现脱漆现象，这样与直接使用镀锌管没有任何区别。

2. The first is the test of the coating adhesion of the zinc steel guardrail. If the coating adhesion is poor, it will not only affect the appearance, but also directly affect the anti-corrosion ability of the zinc steel guardrail. If the anti-corrosion ability is good, the service life of the zinc steel guardrail will be extended, which is at least 4-5 times longer than that of the traditional black iron guardrail, There will be paint stripping, which is no different from the direct use of galvanized pipe.
