Our contemporary door handles, Morphic and Ergo are usually seen in a polished or satin or 2 tone finish. Each finish can give a different aesthetic to the same handle allowing the same handle to be employed in different areas to different effect.
These 2 modern collections of door handles can be cast either in bronze or in stainless steel and the appearance and mood is very different. When you add the textural layer from smooth, to satin to brushed you achieve even greater scope of use.
Consider the Ergo heroic pull as shown here.
The Ergo pull shown on the left is cast 316 stainless steel while the image on the right is silicon bronze. Both were cast using the same mold and by means of the lost wax method of casting. Both metals are resistant to corrosion but the stainless steel is more easy to maintain without the need for any type of sealant. By comparison the bronze unless sealed will tend to become more yellow over time.
As the Ergo handle is extremely fluid with deep recessed areas it lends itself to a sophisticated 2 tone finish. In the detail photo shown below different facets of the handles have been polished or sand blasted to create contrast and depth.
Compare the top sand blasted section of the steel wave to the same section of the bronze version.
