The main raw material of Tieyi guardrail is iron. We all know that iron is very easy to rust. In order to ensure its service life, the guardrail needs to be sprayed with a layer of protective paint to isolate oxygen and avoid oxidation and rust.

鐵藝護欄

Wrought iron guardrail

做好防腐蝕工作可以有效的防止鐵藝護欄外層生銹，防護漆的使用時間也會更長，盡量避免與一些化學物質，例如酸性、堿性物質混合，都能產生化學反應。

Good anti-corrosion work can effectively prevent the outer layer of iron guardrail from rusting, and the use time of protective paint will be longer. Try to avoid mixing with some chemical substances, such as acidic and alkaline substances, which can produce chemical reaction.

大部分鐵藝護欄的安裝使用是在戶外的，戶外的環境沒法控制，防潮這點很難做到，盡可能的在雨水天氣過后擦拭一遍，雖然很麻煩，工程量比較大，但是比較有效的一種防腐蝕方法。

Most of the iron guardrails are installed and used outdoors. The outdoor environment can't be controlled, so it's difficult to prevent moisture. Try to wipe it again after the rain weather as much as possible. Although it's very troublesome and the engineering quantity is relatively large, it's a more effective anti-corrosion method.

防護漆經過長時間的陽光照射也會有脫落的情況出現，因此定期的給鐵藝護欄補漆，發現就及時做修補，這樣才能有效的避免被侵蝕腐蝕。

After a long time of sunlight, the protective paint will fall off. Therefore, we should repair the Tieyi guardrail regularly and repair it in time when we find it. Only in this way can we effectively avoid erosion and corrosion.
