The left and right sides of aluminum alloy door and window hardware accessories are not as simple as we imagined. Even the old birds in the door and window hardware industry sometimes become confused. It can be imagined that an ordinary consumer is forced to face the left and right. In fact, as early as 2008, China National Standardization Management Committee released the national standard GB/T5823-2008 "terminology of building doors and windows". Among them, the left and right sides of door and window hardware accessories are clearly defined. However, eight years after the release of the national standard, a large number of practitioners still know little about it. Among them, business personnel directly facing consumers have once again become the hardest hit area.
I don't know how many times my friends explained the difference between left and right to the customer before the phone call. It took a lot of effort. The customer still seemed to understand it. After the customer came, let me have a try. Every time I see my friend's expression in his throat, I always laugh at him. I can't tell the left and right. What's the use of you, haha. In fact, it's not that my little friend's professional knowledge is not solid, but he didn't find a suitable way of communication, making those raw and difficult professional terms more vernacular.
