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.

　　做車庫門時,組成百葉窗結構大致相同,但在制作的過程中包括材料會有不同的選擇,車庫門的門的身體主要應用材料一般低碳鋼概要文件,如方形管和圓管,大多數是使用不銹鋼門的身體,生產過程分為以下幾方面:

　　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:

　　門體框架及管件出料后應旋轉放置在焊接平臺上，并對尺寸進行焊接驗證。

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

　　采用手工電弧焊，保證焊接質量，不得有不熔透、不熔透、熔渣和燒穿等缺陷，焊后要清除焊接、修磨，不能影響焊接件的強度。

　　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.

　　為了減少焊接變形，應特別注意焊接順序。

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

　　表面處理、門體及附件焊接后，除銹、去污，然后噴涂防銹漆和面漆各兩次，不得有漏噴的缺陷。

　　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.

　　我們走在大街上特別是在晚上,我們可以看到從大型的購物商場個體商店,基本上有各種百葉門,有些普通,一些看美麗的,但有一個受歡迎的價值特征,也就是說,安全,這一點不用多說,材料的選擇嗎?市場上有那么多種類，有那么多選擇，對于選擇綜合癥的人來說不知道如何去好，其實看的就是物質。目前市場上常見的卷簾門材料大致可分為鋁合金、彩鋼和不銹鋼。

　　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.
