My little discussion about portable garages
The S series has high, straight sidewalls and curved arch roof that resists heavy rain and snow accumulation. You have 100 percent usable vertical and floor space by virtue of the high sidewalls; this design grants you the ability to house small manufacturing, industrial and commercial operations or fire and airport fueling stations within its walls. You can even fit your recreational vehicle in an S series industrial steel building. We now come to the Q series industrial steel building. Also known as Quonset huts, Q series buildings with their rounded corrugated arch design are some of the strongest structures in architecture.
