There are many factors affecting the price difference of doors and windows:
1 aluminum surface treatment material
铝合金门窗的铝材表面处理不一样价格也不一样，有的烤漆的50元左右一个平方，粉末喷涂200元左右一个平方，氟碳喷涂400元左右一个平方 木纹大概500元左右一个。单位面积的铝材用量随着截面厚度不一样，价格成本也不一样，1.4的截面和2框格护坡模具 箱体护坡模具 华尔街铜牛 电阻柜 接地电阻柜 电缆保护接地箱 隔离墩模具 化粪池模具.0的截面可能相差100多元钱。好的表面处理用10-20年都不会变色，而有的加入了断桥隔热的设计又会增加300-500元的成本。
The aluminum surface treatment of aluminum alloy doors and windows is different, and the price is also different. Some baking paint is about 50 yuan per square, powder spraying is about 200 yuan per square, fluorocarbon spraying is about 400 yuan per square, and wood grain is about 500 yuan per square. The aluminum consumption per unit area varies with the section thickness, and the price and cost are also different. The section of 1.4 and the section of 2.0 may differ by more than 100 yuan. Good surface treatment will not change color for 10-20 years, while some adding the design of broken bridge insulation will increase the cost of 300-500 yuan.
