如何辨别螺塑钢门窗型材

2017-04-20

1、海螺型材分型号,比如60、88、95,这些型号实际就是塑钢的宽度。自己测量一下,问清具体型号就可分清
2、检查塑钢表面的贴膜,上面写着海螺塑钢蓝色字样。正品海螺是工厂出厂时机器贴膜,平整无皱。假的贴膜不平整,中间有气泡。
3、海螺型材每隔一段距离有海螺的logo后面的一长串数字就是生产的时间和其他信息;
4、真海螺是白中带青、假的是发黄的;
5、拿本海螺手册来看看,看完塑钢的知识差不多就够了,再找本塑钢窗的国家标准手册来看看,那就没有问题了。
6、海螺推荐的厂家,这样的厂家真伪有很大保证。
7、型材几何尺寸达到标准要求。四周几何图形垂直,型材四角达到90度。
8、型材表面光滑平整、发亮、有光泽、无纹路。 
9、型材大、小面均有海螺牌专用保护膜,保护膜文字清晰,有规律。 
10、型材背面的压码标识,清楚有规律。
11、型材几何尺寸达到标准要求。四周几何图形垂直,型材四角达到90度。
12、型材内筋直、腔体光滑无气泡,专用衬钢穿得进。
13、型材厚度分布均匀达到标准厚度无明显颁布不均现象。

14、型材破坏试验应符合行业标准,无裂纹、无气泡,弯曲在一定长度内,有弹性。
