鍍鋅鋼板也叫（白鐵皮）是為防止鋼板表面遭受腐蝕延長其使用壽命，在鋼板表面涂以一層金屬鋅，這種涂鋅的鋼板稱為鍍鋅板。鍍鋅板由于涂鍍工

藝中處理方式不同，表面狀態也不同，如普通鋅花、細鋅花、平整鋅花、無鋅花以及磷化處理的表面等。切成定尺長度的鍍鋅板及鍍鋅卷板不得存在

影響使用的缺陷（以下詳述），但卷板允許有焊接部位等若干不正常部分。鋅花大小由液態鋅的成分來控制的同時，采用強制冷卻的方法來控制,小鋅

花產品在鋅花開始擴散之前,用小鋅花設備進行急冷防止鋅液繼續擴散,形成小鋅花。

Galvanized steel plate is also called (white iron sheet) is to prevent the steel plate surface from suffering corrosion to prolong its service life, in the steel plate

surface coated with a layer of metal zinc, this kind of zinc coated steel plate is called galvanized plate. Galvanized plate due to the different treatment methods in

the coating process, the surface state is also different, such as ordinary zinc flower, fine zinc flower, flat zinc flower, no zinc flower and phosphating treatment

surface. The galvanized plate and galvanized coil plate cut into fixed length shall not have defects affecting the use (detailed below), but the coil shall have several abnormal parts such as welding parts. The size of zinc flower is controlled by the composition of liquid zinc, and the forced cooling method is adopted. Before the product of zinc flower begins to spread, the small zinc flower equipment is used to prevent the zinc liquid to continue to spread and form a small zinc flower.
