自动玻璃门钢架的安装
Installation of automatic glass door steel frame
门体较窄较低的时候，钢架直接打在土建的门洞上方墙体上，用膨胀螺丝吃紧;门体较宽较高的时候，分为门洞上方电焊角铁拉近槽钢，或者立个门中门，重新烧个门洞。钢架烧好之后，需要用油漆把钢架全部粉刷一遍，防止钢架生锈。然后确定玻璃尺寸。
When the door body is narrow and low, the steel frame is directly hit on the wall above the door opening of civil engineering and tightened with expansion screws; when the door body is wide and high, it can be divided into welding angle iron above the door opening to draw near the channel steel, or erect a middle door and burn the door opening again. After the steel frame is burnt, it needs to be painted once to prevent the steel frame from rusting. Then determine the glass size
