Steel doors are a perfect way to create a more seamless boundary between the inside and outside of a home. When the weather is nice they can be installed to swing outward if you have a decent overhang. One caveat, they never seal quite like the French doors you might be replacing. Design over function definitely wins the battle. The design aesthetic lends itself to many different interior design styles. Several great companies include Portella, Durango, and Santiago Iron Works.
