　　一看用料。优质的铝合金门窗设备所用的铝型材，厚度、强度和氧化膜等，应符合有关的国家标准规定，壁厚应在1。

　　A look at materials. High quality aluminum alloy doors and windows equipment used aluminum profiles, thickness, strength and oxide film, should comply with the relevant national standards, the wall thickness should be 1.

　　2毫米以上，抗拉强度达到每平方米毫米157牛顿，屈服强度要达到每平方毫米108牛顿，氧化膜厚度应达到10微米。如果达不到以上标准，就是劣质铝合金门窗设备，不可使用。

　　2 mm or more, the tensile strength reaches the Newton per square millimeter of 157, the yield strength to reach the per square millimeter of 108, the thickness of the oxide film should reach up to 10 microns. If you can not reach the above standards, is the poor quality of aluminum alloy doors and windows equipment, not to use.

　　二看加工。优质的铝合金门窗设备，加工精细，安装讲究，密封性能好，开关自如。

　　Two see processing. High quality aluminum alloy doors and windows equipment, fine processing, installation, good sealing performance, switch freely.

　　劣质的铝合金门窗设备，盲目选用铝型材系列和规格，加工粗制滥造，以锯切割代替铣加工，不按要求进行安装，密封性能差，开关不自如，不仅漏风漏雨和出现玻璃炸裂现象，而且遇到强风和外力，容易将推拉部分或玻璃刮落或碰落，毁物伤人。

　　Aluminum Alloy and equipment quality, choose aluminous profile series and specifications, processing by saw cutting instead of crudely made, milling, no installation required, poor sealing performance, the switch does not freely, not only air leaks and glass burst phenomenon, and encountered strong winds and force, easy to blow push-pull part or glass or fall fall, destroy the thing.

　　公司铝门窗加工机器可完成铝型材的切割，组角，钻孔，冲孔，弯圆等工序，塑钢门窗设备可 完成型材切割，焊接，铣削，清理等工序。十大系列，四十余个品种设备，均得到了广大新老客户的一致好评。
