The pure copper door has a long service life and fine workmanship, which is naturally welcomed by many people. However, with the development of technology, a series of fake copper doors have appeared in the market, so how can we identify the true and the false? Shandong copper door summarizes three opinions for you to identify the true and the false pure copper doors.

一、看是否变色：铜门是通过化学反应来自然变色的，所以真纯铜门不会褪色。但是假的就恰恰相反了。

1、 See if it changes color: copper doors change color naturally through chemical reaction, so pure copper doors will not fade. But fake is the opposite.

二、看是否有锈迹，真纯铜门只要不把保护漆破坏掉，就不会生锈。从工艺来说：真铜门是一种纯手工拼接的工艺门，采用更好的黑胶来粘接，内衬镀锌钢管龙骨，这是其它非标门都没有的一大优势,所以真的纯铜门一般是不易生锈的。相反的，假的铜门就不会这样了。

2、 See if there is rust, as long as the pure copper door does not damage the protective paint, it will not rust. From the perspective of Technology: the real copper door is a kind of pure manual splicing process door, which is bonded with the best black glue and lined with galvanized steel pipe keel. This is a big advantage that other non-standard doors do not have, so the real pure copper door is generally not easy to rust. On the contrary, fake copper doors will not be like this.

三、看是否会褪色，铜跟其它化学药水反应来改变铜本身的颜色，再通过烘干罩光漆来保护铜皮表面不被外界腐蚀,所以真的纯铜门具有不褪色优点。

3、 To see if it will fade, copper reacts with other chemicals to change the color of copper itself, and then the surface of copper skin is protected from external corrosion by drying varnish, so the real pure copper door has the advantage of non fading.
