Surface Condition: The surface condition of galvanized sheets varies due to different processing methods during the coating and galvanizing process, such as ordinary zinc flower, fine zinc flower, flat zinc flower, no zinc flower, and surfaces treated with phosphatization. German standards also specify surface grades.
Galvanized Sheet
