Each scenic image is raised 3/4 of an inch and welded back to the steel frame, giving it a dimensional framed look when hanging on the wall. Each scenic metal wall art masterpiece is plasma cut from 16 gauge cold rolled steel, then finished using several techniques that create a stunning visual effect when the art reflects natural light. The variety of tone and color forged from these techniques ensure that each work of art is unique from one another. To finalize the process the steel art piece is coated with a clear powder coat finish. This industrial process then enables the metal art to be impervious to rust and corrosion by the elements making this wall-hung art piece great for home decorating inside and outside.
