断桥铝门窗市场价格的确很乱，乱的什么程度呢？就拿55断桥门来说吧，便宜的仅300到400左右一平方，而贵的呢，700到800一平方，甚至还有1000多一平方的，这之间差别到底在哪里？从外表看它们并没有什么区别，那问题到底在那呢？今天老狼从材料、工艺和窗型三个方面来给大家做一个比较。
The market price of bridge cutoff aluminum doors and windows is indeed very disorderly, to what extent? Take 55 Broken Bridge Gate as an example. The cheap one is only 300 to 400 square meters, while the expensive one is 700 to 800 square meters, or even more than 1000 square meters. What's the difference between them? From the outside, there is no difference between them. What's the problem? Today, Laolang will make a comparison from three aspects: materials, technology and window type.

1，型材
1. Profile
a、55断桥型材现在市场上厚度从1.2mm到1.8mm毫米都有，仅一根6米长型材仅因厚度不同，差价就有几十元之多。

b，大厂小厂之分：因设备，工北京纯水设备 保定网站制作 排水槽模具艺方面的原因，小作坊生产的型材，加工费每吨在2000多到3000之间，而大厂的每吨加工费达到5000到6000元，这也是个不小的差别哦！
b. The difference between large factories and small factories: due to equipment and technology, the processing cost of profiles produced by small workshops is more than 2000 to 3000 yuan per ton, while that of large factories is 5000 to 6000 yuan per ton, which is also a big difference!
