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.

如果想知道鋅鋼鐵藝護欄的壽命，需要了解冷鍍鋅的特性，冷鍍鋅，質軟而薄，相對于磷化和裸板的防銹效果要好很多，這也就是很多鐵藝護欄廠家說的很久不生銹的道理，為了讓鋅鋼護欄有更多的色彩，我們便在鐵藝護欄的表面做噴涂，噴涂的質量直接導致鋅鋼護欄的防腐能力，如果噴涂做的相對較好的情況下，將對鋅鋼護欄的防腐，耐候性以及附著力將有很大的提升，那么，我們以什么為標準來衡量鋅鋼鐵藝護欄的這些指標呢？

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，在安裝的時候鋅鋼護欄的切口位是個致命的大問題，如果鋅鋼護欄的切口位處理不當，將直接導致切口位短時間生銹，就是正常雨天過后，會從鋅鋼護欄的管里面流黃水出來，這樣就到會降低鋅鋼護欄的使用壽命。

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、就是鋅鋼護欄的噴涂附著力的測試，如果噴涂的附著力差了，不僅影響美觀，而且還直接影響鋅鋼護欄的防腐能力，如果防腐能力較好，將對鋅鋼護欄的使用年限會延長一些，相對比傳統(tǒng)的黑鐵皮護欄使用年限少長4-5倍時間，如果鋅鋼護欄的防腐能力不好，將會出現(xiàn)脫漆現(xiàn)象，這樣與直接使用鍍鋅管沒有任何區(qū)別。

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.
