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(hù)欄有更多的色彩，我們便在鐵藝護(hù)欄的表面做噴涂，噴涂的質(zhì)量直接導(dǎo)致鋅鋼護(hù)欄的防腐能力，如果噴涂做的相對(duì)較好的情況下，將對(duì)鋅鋼護(hù)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(biāo)準(zhǔn)來(lái)衡量鋅鋼鐵藝護(hù)欄的這些指標(biāo)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(shí)候鋅鋼護(hù)欄的切口位是個(gè)致命的大問(wèn)題，如果鋅鋼護(hù)欄的切口位處理不當(dāng)，將直接導(dǎo)致切口位短時(shí)間生銹，就是正常雨天過(guò)后，會(huì)從鋅鋼護(hù)欄的管里面流黃水出來(lái)，這樣就到會(huì)降低鋅鋼護(hù)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(hù)欄的噴涂附著力的測(cè)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(hù)欄的防腐能力，如果防腐能力較好，將對(duì)鋅鋼護(hù)欄的使用年限會(huì)延長(zhǎng)一些，相對(duì)比傳統(tǒng)的黑鐵皮護(hù)欄使用年限少長(zhǎng)4-5倍時(shí)間，如果鋅鋼護(hù)欄的防腐能力不好，將會(huì)出現(xiàn)脫漆現(xiàn)象，這樣與直接使用鍍鋅管沒(méi)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.
