The weight of shrink film packaging is 25±5 Kg/ton, and the weight of paper packaging is 50±5 Kg/ton. 1. Extruded or blank aluminum profiles, plus packaging, the actual weight = theoretical order weight * 1.025 (shrink film); 2. Anodized or electrophoretic paint, the actual weight per ton after integration = theoretical order weight * 1.03 (shrinkage film) film); 3. Powder coating: the weight of the powder is based on the section size and wall thickness difference, the content of the powder is 45±5 Kg/ton, the actual weight per ton after integration = theoretical order weight * 1.07 (shrink film); 4. Thermal insulation Bridge 20mm width insulation strip: weight 105 Kg/ton; 25mm width insulation strip: weight 140 Kg/ton. After integration, the actual weight per ton = theoretical order weight * (1.14~1.18) (shrink film). The measurement of aluminum alloy profiles is based on actual accounting. Except for the large difference in the weight of the thermal insulation broken bridge, other surface treatments must be inquired about the customer's purchase details in detail. Use the deposit to lock the price of aluminum ingots on the day or lock the average price of the week
The aluminum profile is settled according to the actual situation. When the mold is opened, the negative tolerance is taken. The weight belongs to the manufacturer's control index. The density of aluminum is 2.7. Tolerance measurement, after adding the weight of the package and powder, is slightly higher than the theoretical weight of the aluminum profile
The foreign trade export of aluminum alloy profiles is based on the weight of the actual machine. The weight cannot be higher than 3% of the theoretical weight, nor can it be lower than 3% of the theoretical weight.
