The production of aluminum profile frame is the frame profile produced by extrusion of aluminum bar.
Corrosion resistance: the density of aluminum profile is only 2.7g/cm3, about 1 / 3 of that of steel, copper or brass (7.83g/cm3, 8.93g/cm3, respectively). In most environmental conditions, including air, water (or salt water), petrochemistry and many chemical systems, aluminum can show excellent corrosion resistance.http://www.yanghe1al.com/aluminum-profiles/
