Generally speaking, iron gate should be installed with electric lock. Electronic lock is a mechanical lock device controlled by relay. At present, a series of products with different structures have been formed, including electric plug lock (male lock), cathode lock (electric lock port), magnetic lock, electric control lock, etc. Now I'd like to introduce how to install the electric control lock of iron gate.
                                           

鐵藝大門的挑選專家總結一下三點：1、你要選擇好鐵藝店看他們店內鐵藝模型的銹蝕程度，還要查看焊的花葉子是否結實，以此來評定他們工藝的好壞。2、鐵藝門盡量不要選擇鍍鋅管的（如果你真的喜歡也沒辦法）因為鍍鋅管原料很便宜（比起方鋼還不行）我們還是賣方鋼的門比較多。3、鐵藝門盡量選擇小巧一點的，小巧的更顯雅道，好看  如果是小門就選擇黑色的，大門就選擇古銅吧，至于紅古銅還是黃古銅或綠古銅就隨你喜歡了。鐵藝門其實沒有什么特別要注意的，就是好看、結實、防腐程度高。

The selection experts of the iron gate summed up three points: 1. You should choose a good iron shop to see the corrosion degree of the iron model in the shop, and also check whether the welded flowers and leaves are strong, so as to evaluate the quality of their technology. 2. Try not to choose galvanized pipe for Tieyi door (if you really like it, you can't do it) because the raw material of galvanized pipe is very cheap (not as good as square steel). We still have more steel doors from the seller. 3. Iron door as far as possible to choose a small point, small more elegant road, good-looking, if it is a small door to choose black, the door on the choice of bronze bar, as for red bronze or yellow bronze or green bronze as you like. In fact, there is nothing special to pay attention to, that is, good-looking, strong, high degree of anti-corrosion.

別墅鐵藝大門在一般的情況下，的別墅入戶門因生產成本高，價格比劣質的別墅門要高許多。有些壁厚僅0.6--0.8mm的鋁板制作的別墅入戶門，抗拉強度和屈服強度大大低于國家有關標準規定。使用很不安全。

Villa iron gate in general circumstances, because of the high production cost, the price of the villa door is much higher than that of the inferior villa door. The tensile strength and yield strength of some villa entrance doors made of aluminum plate with wall thickness of only 0.6-0.8mm are much lower than the relevant national standards. It's not safe to use.
