What is the problem of choosing a corner

The corner is made in different ways, which gives it very specific properties. For example, a hot-rolled steel corner (by rolling a square steel billet) is more durable than a bent corner made by bending or forging.
Depending on the length of the shelves, the corner is classified into equal and unequal. The first is considered more reliable, therefore, the most popular when used. The second option is often used in the construction of various frame structures, while in critical structures they prefer, again, a hot-rolled profile that can withstand serious loads.
