First of all, to determine the customer requirements is a flower galvanized sheet or hot sale galvanized steel coil without zinc flowers, flowers to be used a little. The thickness of 0.18-3.0mm is commonly used, and the width is mainly concentrated in 1000mm or 1250mm. The relevant product standards all list the recommended standard thickness, length, and width of galvanized sheet and its allowable deviation. The thickness deviation is generally 0.05mm, the length and width deviation is generally 5mm, and the thickness of the plate is generally between 0.4-3.2. Generally speaking, the thicker galvanized steel coil allows greater error, rather than fixed 0.02-0.04mm, thickness deviation is also based on yield, tensile coefficient, and other different requirements, the width of the deviation is generally in 5mm, the thickness of the galvanized steel coils generally between 0.4-3.2. Common galvanized sheet thickness in 0.4~2.0 is generally less than 0.4mm state-owned big steel mill production, as a private small steel mill production, the general specification is 0.35, 0.30, 0.28, 0.25, generally the thinnest to 0.15 more than 2.0mm due to straightening difficulty is very large, so more than 2.0 with the increase in thickness of the price is also rising.
