What it is made

Do not think that by choosing the most protected door is unnecessary to pay attention to its appearance. Mainly pay attention to the finish, more precisely what it is made of — metal, wood or other materials. In addition, you need to determine what thickness the metal has, because the reliability of the entire structure depends on it. The thicker the metal, the more protected the door, and you can protect you from distortions. Inspect the door well and pay attention to everything — so that welding seams are of high quality, and the metal is of good quality.
