The most difficult thing for iron railings is the treatment of paint. How to make them durable and rust-free and prolong their service life? So today we will talk about how to make the greatest extension of the service life of iron railings - paint treatment:

　　首先讓我們來談談鐵的生產工藝:以前我們沒有用鍍鋅管，我們用的都是黑鐵管，這種管的表面沒有經過任何處理，俗稱:黑鐵，這種材料容易氧化生銹，一般需要經過酸洗磷化、砂光拋光處理，然后再進行底漆防銹處理。這個過程既復雜又耗時、成本高，隨著鍍鋅管和靜電噴涂的出現，大大節省了時間和成本。

　　First let's talk about the production process of iron: before we did not use galvanized pipes, we used black iron pipes, the surface of this kind of pipe has not been treated, commonly known as: black iron, this material is easy to oxidize and rust, generally need to be treated by acid pickling, phosphating, sanding and polishing, and then anti-rust treatment of primer. This process is complex, time-consuming and costly. With the emergence of galvanized tubes and electrostatic spraying, time and cost are greatly saved.

　　現在讓我們來談談這款鍍鋅管:鍍鋅管分為普通市場管和專門用來制作護欄管的護欄管，護欄管常規規格:16*16 19*19 32*32 40*40 45*45 50*50 50* 60 60* 70 60*60 80*80，以此類推。這種管一般用于鋅鋼護欄的沖壓裝配，雖然這種護欄管被稱為電鍍鋅護欄，但這一過程應稱為冷鍍鋅，近年來環保方面的努力，熱鍍鋅廠已基本停工整頓，基本上改用這種冷鍍鋅管代替。

　　Now let's talk about this kind of galvanized pipe: galvanized pipe is divided into ordinary market pipe and guardrail pipe specially used for making guardrail pipe. The conventional specification of guardrail pipe is 16*16*19*19*32*32*40*40*45*45*50*50*60*70*60*60*80*80, and so on. This kind of pipe is usually used for stamping and assembling of galvanized steel guardrail. Although this kind of guardrail pipe is called galvanized guardrail, this process should be called cold galvanizing. In recent years, efforts in environmental protection, hot galvanizing plants have basically stopped working and rectified, basically replaced by this kind of cold galvanized tube.

　　然后我們來談談鐵藝護欄的生產工藝:切割-焊接-拋光-除銹處理-靜電噴涂-成品包裝。防銹處理和靜電噴涂是更關鍵的。

　　Then we will talk about the production process of iron guardrail: cutting - Welding - polishing - rust removal treatment - electrostatic spraying - finished product packaging. Anti-rust treatment and electrostatic spraying are the most critical.

　　嗯，鐵藝欄桿更大的問題之一是它們會生銹。當然，不能讓它們生銹，面對這一個問題，這就需要我們對鐵銹底漆和靜電漆進行更多的上光處理，這樣我們才能使鐵藝欄桿長時間不受天氣的影響生銹。

　　Well, one of the biggest problems with iron railings is that they rust. Of course, they can not be rusted. Faced with this problem, we need to polish more rust primer and electrostatic paint, so that we can make iron railings rusty for a long time without the influence of weather.
