彩钢门窗为什么用冷轧镀锌为基板？

Why do color steel doors and Windows use cold-rolled galvanized as the substrate?

彩钢门窗是指以冷轧镀锌板为基板，涂敷耐候型高抗蚀面层，由现代化工艺制成的彩色涂层建筑外用卷板（简称“彩板”）作为生产门窗的原材料。我国只有宝钢、武钢以及广东、北京等少数企业能够生产这种专用材料。由于这种门窗以彩板为原料所以称为彩板门窗。防火门生产工艺为：镀锌板（冷板）→压型→前处理（酸洗、磷化）→涂装→ 固化→冷却→组装。

Color board doors and Windows refer to the cold-rolled galvanized plate as the substrate, weather resistant high corrosion resistance coating, color coated building coil (referred to as "color board") as the raw material for the production of doors and Windows.Only Baosteel, Wuhan Iron and Steel, and a few enterprises such as Guangdong and Beijing can produce such special materials.Because this kind of doors and Windows with color plate as raw material, so called color plate doors and Windows.The production process of fire door is: galvanized plate (cold plate) pressure before treatment (pickling, phospholation) coating curing and cooling assembly.

彩涂镀锌卷材经专用机组分剪制成带材，再用冷弯成型连续轧制成封闭的门窗专用异型管材，然后再经深加工制成彩板门窗。

Color coated galvanized plate is cut into strips by special machine components, and then with cold bent continuous rolling into closed doors and Windows, and then through deep processing into color plate doors and Windows.

马钢彩涂板的基板可以分成冷轧基板、热镀锌基板、电镀锌基板。马钢彩涂板的种类可以分成：聚酯、偏聚二氟、马钢彩涂板的颜色可以按用户的要求分成很多种类如桔黄、奶黄、深天蓝、海蓝、绯红、马钢彩涂板的表面状态可以分成板、压花板、印花板。马钢彩涂板钢板市场用途主要分为建筑、家电和交通运输等三分，其中建筑领域所占比例大，家电业次之，交通运输业只占较少一分。建筑用马钢彩涂板一般以热镀锌钢板和热镀铝锌钢板为基板，主要加工成瓦楞板或与聚氨酯复合夹芯板后，用于建造钢结构厂房、库房、冷冻库等工业和商业建筑的屋顶、墙面、门。 

The substrate of Maanshan color coating can be divided into cold rolled substrate, hot galvanized substrate and galvanized substrate.The types of steel color coating plate can be divided into: polyester, pole difluoride, steel color coating plate can be divided into many kinds of orange, cream, dark blue, sky blue, navy blue, crimson, steel color coating surface state can be divided into plate, embossed plate, printing plate.The market use of Maanshan steel color coated plate is mainly divided into three points of construction, home appliances and transportation, among which the construction field accounts for a large proportion, home appliance industry, and transportation industry only accounts for a small point.Building horse steel color coating plate generally with hot galvanized steel plate and hot aluminum galvanized steel plate as the substrate, mainly processed into corrugated plate or composite sandwich plate with polyurethane plywood, for the construction of steel structure roof, warehouse, freezer and other industrial and commercial buildings, walls, doors.
