Want to know the life of zinc steel guardrail, first need to understand the characteristics of cold galvanizing, cold galvanizing, soft and thin, relative to phosphating and bare plate rust prevention effect is much better, this is a lot of iron guardrail manufacturers say for a long time does not rust truth

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？

In order to make the zinc steel guardrail have more colors, we will spray on the surface of the iron guardrail. The quality of spraying directly leads to the anti-corrosion ability of the zinc steel guardrail. If the spraying is relatively good, the anti-corrosion, weatherability and adhesion of the zinc steel guardrail will be greatly improved. Then, what is our standard to measure these indicators of the 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，將會出現脫漆現象，這樣與直接使用鍍鋅管沒有任何區別。

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.
