随着热轧工艺技术的发展，热轧产品质量不断提高，厚度逐渐减薄，采用热轧薄板为原料生产热轧镀锌板替代了原来传统的单张镀锌，不仅拓宽了热轧镀锌板的使用范围，而且也挤占了以冷轧板为基板的热镀锌板市场份额。在国际上，热轧镀锌板已经得到广泛的采用。

With the development of hot rolling technology, the quality of hot rolled products is constantly improved, and the thickness is gradually thin. Using hot rolled sheet as raw material to produce hot rolled galvanized plate replaces the original traditional sheet galvanized, which not only broadens the scope of hot rolled galvanized plate, but also occupies the market share of hot rolled galvanized plate with cold rolled plate as the substrate.Internationally, hot-rolled galvanized sheet has been widely adopted.

热轧镀锌板是以热板为基板经过酸洗后直接镀锌，与传统镀锌板相比，由于少了冷轧这道工序而有着明显的价格优势，在建筑、汽车制造、钢板仓制造、铁路客车制造、高速公路护栏板、制造等行业有着良好的发展前景。

Hot-rolled galvanized plate is hot plate as the substrate after pickling directly galvanized, compared with the traditional galvanized plate, due to the lack of cold-rolled this process and has obvious price advantages, in the construction, automobile manufacturing, steel plate warehouse manufacturing, railway bus manufacturing, highway guard plate, manufacturing and other industries has a good development prospect.

热轧镀锌在钢结构行业主要用于轻钢结构房屋和厂房，其主要建筑骨架均采用镀锌冷弯型钢，主要是C型钢、Z型钢、楼层承重板及钢天沟的制造，厚度规格主要为1.5-3.5mm。由于钢结构建筑自重轻、强度高、造型美、施工快、污染少、防风抗震性能好，是环保型的“绿色建材”。在发达国家厂房、民用住宅等使用钢结构已成为建筑发展的潮流，在我国建筑钢结构还处于起步阶段，有很大的发展窨和潜力。根据台湾地区的数据显示，彩涂板和热基板镀锌在建筑方面的使用比例一般为5：1。以此计算，我国热基板镀锌板市场的需求量约在60万吨。

Hot rolled galvanizing in the steel structure industry is mainly used in light steel structure houses and factories, its main building skeleton are galvanized cold bending steel, mainly C-shaped steel, Z-shaped steel, floor bearing plate and steel gutter manufacturing, the thickness specification is mainly 1.5-3.5mm.Because the steel structure building weight is light, high strength, beautiful shape, fast construction, less pollution, good wind and seismic performance, is an environmentally friendly "green building materials".In the developed countries workshop, civil housing and other use of steel structure has become the trend of building development, in China's building steel structure is still in the initial stage, there is a great development of scenting and potential.According to the data from Taiwan region, the proportion of color coating plate and thermal substrate galvanizing used in construction is generally 5:1. Based on this calculation, China's hot substrate galvanized plate market demand is about 600,000 tons.
