Steel and aluminum are not interchangeable; they answer different questions.
Steel wins on stiffness and presence. Long spans, slender profiles that still feel solid, welded connections that read as one material — steel is the metal of structure. It needs a coating system to survive outdoors, and that system must be specified properly: preparation, primer, powder, thickness.
Aluminum wins on weight and corrosion resistance. It suits moving parts, coastal exposure and large sliding elements. But it dents, it flexes, and its extruded profiles carry a different visual language — crisp, but lighter in every sense.
At FORGIA the rule is simple: where the work is structural and permanent, steel. Where it moves or faces salt, aluminum considered honestly. The wrong metal, beautifully finished, is still the wrong metal.
