镀锌板理论重量计算公式

1、 镀锌彩钢板理论重量计算公式w=7.85×[D-（W1△50）×7.1△1000]W1，其中D为镀锌板的标称订货厚度，单位为mm；W1为镀层标称重量，单位为克/平方米。

2、 镀锌彩钢板理论重量计算方法计算顺序计算方法四舍五入基体基本重量[kg/（mm·m2）]7.85（厚度为1mm，面积为1m2）-基体单位重量（kg/m2）基本重量[kg/（mm·m2）×[订货标称厚度（mm）-标称镀层厚度（mm）]四舍五入至有效数字，镀锌后单位重量（kg/m2）底板单位重量（kg/m2）镀锌层标称重量（kg/m2）四舍五入至有效数字镀锌钢板四位数面积（m2）宽度（m）×长度（m）四舍五入至有效数字镀锌钢板四位数重量（kg）单位重量（kg/m2）×面积（M2）四舍五入至有效数字四位数字镀锌钢板重量（kg）镀锌钢板重量（kg）×钢板数量约为kg整数值总重量（kg）每捆钢板重量之和kg整数值3。 镀锌彩钢板层名义厚度计算方法D1=（W1△50）×7.1△1000，式中D1为镀层标称厚度，单位为mm；W1为镀层标称重量，单位为g/m2【50g/m2镀层厚度约为7.1μM】。

Calculation formula of theoretical weight of galvanized sheet

1、 The theoretical weight calculation formula of galvanized sheet w = 7.85 × [D - (W1 △ 50) × 7.1 △ 1000] W1, where D is the nominal ordering thickness of galvanized sheet, in mm; W1 is the nominal coating weight, unit: g / m2.
2、 Calculation method of theoretical weight of galvanized sheet calculation sequence calculation method rounding off basic weight of substrate [kg / (mm · m2)] 7.85 (weight of thickness of 1 mm, area of 1 m2) - unit weight of substrate (kg / m2) basic weight [kg / (mm · m2)] × [ordering nominal thickness (mm) - Nominal plating thickness (mm)] rounded to significant figures, unit weight after galvanizing (kg / m2) Base plate unit weight (kg / m2) nominal zinc coating weight (kg / m2) rounded to significant figure 4-digit area of galvanized steel sheet (M2) width (m) × length (m) rounded to significant figure 4-digit weight of a galvanized steel sheet (kg) unit weight (kg / m2) × area (M2) rounded to significant figure 4-digit weight of single bundle of galvanized steel sheet (kg) weight of a galvanized steel sheet (kg) × number of steel plates About to kg integer value total weight (kg) the sum of the weight of each bundle of steel plates kg integer value 3. Calculation method of nominal thickness of zinc coating D1 = (W1 △ 50) × 7.1 △ 1000, where D1 is the nominal coating thickness, unit is mm; W1 is the nominal coating weight, unit is g / m2 [plating thickness of 50 g / m2 is about 7.1 μ M].
