The new security door is too big and wants to remove the edges, what should I do? If you want to cut

The new security door is too big and I want to remove the edges. If you want to cut, how should you pass the new security door, if you want to remove the edge of this cut, it should be some small, this should be the average edge of the re-cut those irrelevant places.

It's better to find a professional, otherwise, you won't get it, and if you ruin it, it's ruined.

First, it is necessary to measure the actual data, such as the width and length of the door, and then take a good position on the security door, draw the width and length of the entire door, and then draw each line parallel to this frame, and then draw a frame about 5-8 cm from the distance, so that there are two frames, and then cut along the large frame with a chainsaw, after cutting, cut it with a chainsaw at the corner between the two frames, the distance is the distance between the large frame and the small frame, and then move the excess small frame with pliers. 90 degrees, feel too long, just move the steel piece to the inside, and then 90 degrees, pay attention, do not install the security door to those fixed points, otherwise, it can not be installed, you can properly move the two frames to the installation point.

It's best to find a professional, because it's a big project.

Start by marking the part you want to cut with a pen, then use a portable metal cutter to cut it by wire! (Please be safe, it is best to call a professional, and wear flat glasses so that the chips do not get into the eyes), and finally use a polisher to sharpen the burr.

It's best to hit the wall and enlarge the door opening.
