Quick answer
Steel is stronger per dollar, easier to wind-rate and better insulated; aluminium resists corrosion and suits modern full-view designs but costs more. For most Florida homes, coastal-coated steel is the practical default — see garage door installation.
Material choice decides how the door copes with wind, salt and sun.
Steel
Insulated sandwich steel takes wind ratings easily and is the most cost-effective. Specify a marine-grade finish near the coast.
Aluminium
Will not rust, suits glass and contemporary styles, but dents more easily and needs careful rating.
