First remove the chain and press the button "-" to turn the motor to the automatic stop position, then close the door to install the chain, otherwise press the button "+" to the automatic stop position to install the chain when it is fully open. Your problem will occur when you do not install at the lowest or highest price. Click here to debug.

　　做车库门时,组成百叶窗结构大致相同,但在制作的过程中包括材料会有不同的选择,车库门的门的身体主要应用材料一般低碳钢概要文件,如方形管和圆管,大多数是使用不锈钢门的身体,生产过程分为以下几方面:

　　When making a garage door, the structure of the louver is basically the same, but there are different choices in the manufacturing process, including materials. The body of the garage door is mainly made of general low-carbon steel profiles, such as square and round pipes, most of which are made of stainless steel doors. The production process is divided into the following aspects:

　　门体框架及管件出料后应旋转放置在焊接平台上，并对尺寸进行焊接验证。

　　The door frame and pipe fittings shall be placed on the welding platform after discharging, and the size shall be verified by welding.

　　采用手工电弧焊，保证焊接质量，不得有不熔透、不熔透、熔渣和烧穿等缺陷，焊后要焊接、修磨，不能影响焊接件的强度。

　　Manual arc welding shall be adopted to ensure the welding quality, and there shall be no defects such as non penetration, non penetration, slag and burn through. After welding, the welding and grinding shall be removed, and the strength of the weldment shall not be affected.

　　为了减少焊接变形，应特别注意焊接顺序。

　　In order to reduce welding deformation, special attention should be paid to welding sequence.

　　表面处理、门体及附件焊接后，除锈、去污，然后喷涂防锈漆和面漆各两次，不得有漏喷的缺陷。

　　After surface treatment, door body and accessories are welded, derusting and decontamination shall be carried out, and then anti rust paint and finish paint shall be applied twice respectively, without any missed spraying.

　　我们走在大街上特别是在晚上,我们可以看到从大型的购物个体商店,基本上有各种百叶门,有些普通,一些看美丽的,但有一个受欢迎的价值特征,也就是说,,这一点不用多说,材料的选择吗?市场上有那么多种类，有那么多选择，对于选择综合症的人来说不知道如何去好，其实看的就是物质。目前市场上常见的卷帘门材料大致可分为铝合金、彩钢和不锈钢。

　　When we walk on the street, especially in the evening, we can see that there are basically all kinds of shutter doors in the individual stores of large shopping malls, some of which are ordinary, some of which are beautiful, but there is one most popular value feature, that is, safety, needless to say, Is there a choice of materials? There are so many kinds and choices in the market. For people with choice syndrome, they don't know how to do well. In fact, the most important thing is materials. At present, the common rolling shutter door materials in the market can be roughly divided into aluminum alloy, color steel and stainless steel.
