Why are the steel structure ceilings of gas stations mostly flat roofs?

Because the steel structure canopy of the gas station has no enclosure on three sides except the station building, and the surrounding area is relatively open, the steel structure ceiling system needs to meet the wind-proof design requirements.
Since the products operated by gas stations are inflammable and explosive materials such as diesel, gasoline, and liquefied petroleum gas, the steel structure ceiling system needs to meet the fire protection requirements.
The steel structure canopy of the gas station is exposed to the outdoors for a long time, and the ceiling material needs to meet the requirements of good weather resistance, high structural strength, and easy cleaning.
For the steel structure ceiling, it is also necessary to meet the requirements of convenient disassembly and standardization of replication.
The steel structure flat roof is the most material-saving and cost-saving in the construction and laying of panels.
Due to the long-term exposure to wind and sun, daily protection and maintenance or timely replacement of damage is required. The flat-topped type has an advantage which is very convenient for installation that only need to list the panels as sequence, but the disassembly is more crucial. The ceiling will dust accumulation in the daily use, it makes it feel older. Therefore, removing the panel as sequence to scrub in necessary time, after that install it.
