How to choose pre-engineered building manufacturers?

For me, the internet was the solution. I searched on the Internet about the local

Pre-engineered building manufacturers (PEBs). I got many results. I personally spoke to them over the phone and went to their websites. I had listed down the criteria before selecting a manufacturer. The criteria were:

1. I understood what kind of process and the dedication they put into creating the pre-engineered metal buildings.

2. My focus was mainly opting for the manufacturer who can create accurately sized PEBs.

3. I wanted someone who could provide a better option when compared to the traditional structured steel buildings.

4. I would like to choose a manufacturer who would resolve my doubts about the components before I buy them.
