建筑用金屬薄板是指在建筑中使用的金屬薄板，包括鋁板、不銹鋼板、鍍層鋼板和彩涂板等。在建筑中應(yīng)用的產(chǎn)品主要是壓型金屬板。

Metal sheet for construction refers to the metal sheet used in construction, including aluminum plate, stainless steel plate, coated steel plate and color coating plate, etc. The main products used in the construction are the pressed metal plates.

目前，彩涂板鍍層板主要是鍍鋅板，主要用于樓板(包括混凝土板底板)。鋁板和不銹鋼板應(yīng)用不多，可用于建筑屋面、墻面、幕墻和室內(nèi)裝飾。

At present, the color coated plate coated plate is mainly galvanized plate, mainly used for floor plate (including concrete plate bottom plate). Aluminum and stainless steel panels are not used much, and can be used for building roof, walls, curtain walls and interior decoration.

彩涂板包括彩涂鋁板和彩涂鋼板，彩涂鋼板國際上定名為“預(yù)涂層鍍鋅薄鋼板”。彩涂鋼板是在基板經(jīng)過預(yù)處理后，涂覆一層或者多層有機涂料，再經(jīng)過烘烤之后形成的復(fù)合材料。因其多呈卷裝供貨，也可稱為彩涂卷板。

Color coated steel plate includes color coated aluminum plate and color coated steel steel plate, color coated steel steel plate is internationally named as "pre-coated galvanized thin steel plate". Color-coated steel plate is a composite material formed after the substrate is coated with one layer or multilayer of organic coating and then after baking. Because of its more coil supply, can also be called color coated roll board.

耐銹蝕性差是鋼材屬性的重要特點之一。鋼材的銹蝕會嚴(yán)重影響鋼結(jié)構(gòu)構(gòu)件的安全性，并減少其使用壽命。鋼材需要采取長效防護措施實現(xiàn)長期使用的效果。目前，鋼結(jié)構(gòu)構(gòu)件的防腐主要采取防腐涂層的方法。由于常用彩涂鋼板的壓型鋼板厚度僅0.5～3.0 mm，對銹蝕造成的安全性影響更為敏感。因此彩涂鋼板的耐久性是用戶非常關(guān)注的問題。彩涂鋼板一般采取鍍層加涂層的防護措施。

Poor corrosion resistance is one of the important characteristics of steel properties. The corrosion of steel will seriously affect the safety of steel structure members, and reduce its service life. Steel needs to take long-term protective measures to achieve long-term use effect. At present, the anticorrosion of steel structure members mainly adopts the method of anticorrosion coating. Because the thickness of the commonly used color-coated steel plate is only 0.5~3.0 mm, it is more sensitive to the safety impact caused by corrosion. Therefore, the durability of the color-coated steel plate is a very concerned problem of users. Color-coated steel plate generally adopts the protective measures of coating and coating.
