1. Steel: generally, some corrosion-resistant steel is selected for prefabricated house, which is generally called weathering steel; the weathering steel contains phosphorus, copper, nickel, chromium, titanium and other metals, which will form a high protective effect on the steel surface, so as to improve the corrosion resistance of the steel; the movable plank house is directly facing the natural climate of sunlight, rain, frost and snow, and the low-temperature impact toughness of the weathering steel is also It is superior to ordinary structural steel.

2.高溫鋅：熱浸鋅是一種耐高溫產(chǎn)品；其制作工藝達(dá)到600度高溫浸泡。鋼構(gòu)件表面有這樣一層鋅層，而且鋅層的厚度已經(jīng)達(dá)到了5微米，而且附著在鋼構(gòu)件表面的鋅層也有詳細(xì)規(guī)定，薄板不得小于65微米，厚板不得小于86微米。從而耐高溫，耐腐蝕。這種工藝的優(yōu)點(diǎn)是高溫不易變化，周期長，質(zhì)量有保證。因此，本產(chǎn)品廣泛應(yīng)用于戶外大型鋼結(jié)構(gòu)，然后清洗；對于鋼結(jié)構(gòu)的設(shè)計，我們應(yīng)避免設(shè)計有粘結(jié)面的構(gòu)件，以避免粘結(jié)面縫隙中酸洗不徹底或酸洗；導(dǎo)致鍍鋅表面出現(xiàn)黃水。熱浸鋅是在高溫下進(jìn)行的。

2. High temperature zinc: hot dip galvanizing is a kind of high temperature resistant product; its production process reaches 600 ℃ high temperature immersion. There is such a layer of zinc layer on the surface of steel member, and the thickness of zinc layer has reached 5 μ m, and the zinc layer attached to the surface of steel member is also specified in detail. The thin plate shall not be less than 65 μ m, and the thick plate shall not be less than 86 μ M. Therefore, it is resistant to high temperature and corrosion. The advantages of this process are that the high temperature is not easy to change, the cycle is long and the quality is guaranteed. Therefore, this product is widely used in outdoor large-scale steel structure, and then cleaning; for the design of steel structure, we should avoid the design of components with bonding surface, so as to avoid incomplete pickling or pickling in the gap of bonding surface, resulting in yellow water on galvanized surface. Hot dip galvanizing is carried out at high temperature.

3.涂層方法：涂層的耐蝕性一般不如高溫鋅，所以室外鋼結(jié)構(gòu)多用在室內(nèi)鋼結(jié)構(gòu)或相對容易維護(hù)。這種涂料的特點(diǎn)是成本低，更多地用于室內(nèi)鋼結(jié)構(gòu)。這種涂料防銹，不需要耐高溫，也不需要直面大自然的氣候。涂裝法施工的步是除銹，涂裝比高溫鋅除銹要求更高，所以要求高的涂裝一般采用噴砂噴丸去除全部鐵銹和油污。野外施工的涂料可以手工除銹。涂層對環(huán)境要求更高。涂料施工環(huán)境要少揚(yáng)塵，構(gòu)件表面不能有灰塵，涂裝后四小時內(nèi)不能下雨。不同的涂層對不同的腐蝕條件有不同的抵抗能力。

3. Coating method: the corrosion resistance of coating is generally not as good as that of high temperature zinc, so outdoor steel structure is mostly used in indoor steel structure or relatively easy to maintain. This kind of coating is characterized by low cost and is more used in indoor steel structure. This kind of coating is rust proof and does not need to be resistant to high temperature and natural climate. The first step of coating method is rust removal, which requires more than high temperature zinc rust removal. Therefore, sandblasting and shot peening are generally used to remove all rust and oil stains. The paint applied in the field can be derusted by hand. The coating has higher environmental requirements. There should be less dust in the coating construction environment, there should be no dust on the surface of the components, and there should be no rain within four hours after coating. Different coatings have different resistance to different corrosion conditions.

4.熱噴涂鋁(鋅)復(fù)合涂層：該涂層的優(yōu)點(diǎn)是對構(gòu)件尺寸具有較強(qiáng)的適應(yīng)性，幾乎可以制成零件的形狀和尺寸。另一個優(yōu)點(diǎn)是，該涂層的高溫是局部的，因此不會因高溫而發(fā)生變化。

4. Thermal spraying aluminum (zinc) composite coating: the advantage of the coating is that it has strong adaptability to the size of components, and can almost be made into the shape and size of parts. Another advantage is that the high temperature of the coating is local, so it will not change due to high temperature.

與此相結(jié)合，鋼結(jié)構(gòu)活動板房的耐蝕性越來越強(qiáng)，現(xiàn)代工藝處理也越來越完善。活動板房的主要結(jié)構(gòu)是鋼，活動板房的質(zhì)量取決于鋼的質(zhì)量和涂層的質(zhì)量。

Combined with this, the corrosion resistance of steel structure movable plank house is more and more strong, and the modern process treatment is also more and more perfect. The main structure of prefabricated house is steel. The quality of prefabricated house depends on the quality of steel and coating.
