Quality grade of galvanized sheet quality requirements including size, appearance, quantity of galvanized mechanical properties, chemical composition, shape, and packing and so on several aspects. Packaging can be divided into cut into specified length of galvanized sheet and coil galvanized sheet packing two kinds. Relevant product standard size ( And in the following) All listed recommended standard of galvanized sheet thickness, length and width and allowable deviation. In addition, the plate width and length, the width of the roll can be determined according to the requirements of customers. Exterior surface state: due to the plating process of galvanized sheet processing in a different way, different surface state, such as ordinary zinc flowers, fine zinc, zinc zinc flowers, no flowers and phosphating treatment surface, etc. Cut into specified length of galvanized sheet and galvanized coil plate may not have any influence to use defects ( The following details) But rolled plate welding parts and so on a number of abnormal parts are allowed.

There are two sides to galvanized the same amount ( The thickness of galvanized) And two different galvanized ( The poor thick galvanized) Two kinds. Galvanized quantity unit is g/m2. Mechanical properties ( 1) Tensile test: generally speaking, only structure, stretching and deep drawing with galvanized sheet tensile performance requirements. （ 2) Bending test: is the main measure of process performance of sheet project. But the national standard requirement for all kinds of galvanized sheet is not consistent. General requirements galvanized sheet bending after 180 o, the lateral surface can not have the zinc layer from, plate base can not have crack and fracture. Chemical composition of the chemical composition of a galvanized substrate requirements, to the different standards. As Japan is not request, the United States. Generally does not make the finished product inspection. Flatness measured strip shape quality, there are two indicators, namely, straightness and rocker. The straightness and maximum allowed standard has certain provisions of the rocker. Below is a list of the galvanized sheet major foreign standards to reference [ 4, 5) : JISG3302 galvanized steel JISG3313 electric galvanized steel plate and steel belt ASTMA525 the general requirements of hot dip galvanized steel sheet ASTMA526 commercial grade hot dip galvanized steel sheet ASTM527 bite molding grade hot dip galvanized steel sheet ASTM528 level deep drawing hot dip galvanized steel sheet ASTMA361 roof and wall panel with hot dip galvanized steel sheet ASTMA444 ditches with hot dip galvanized steel sheet ASTMA446 level structure of hot dip galvanized steel sheet.
