Add rounded corners in metal plate Angle place, make it not sharp, increase their sexual contact.
In order to remove the parts because of the machining burrs, also in order to facilitate part assembly, generally at the end of the parts made of Chamfering is 45 ° more, also can be made into 30 ° and 60 °.

It is more difficult to bend rectangular tube than round tube. The tighter the bend, the more difficult it is to do correctly. The same holds true for wall thickness: thinner walls are more difficult. Most commonly, rectangular tube is bent either the "hard way" (x-x axis) or the "easy way" (y-y axis). It is usually the case however, that even though more pressure is required to bend a tube the hard way, the resultant curved member is less likely to distort precisely because it is more rigid than a section curved the easy way. Easy way bending more likely will result in the inside diameter becoming somewhat concave.
