Modern society requires a large number of large, wide, high precision and complex cross section of the thin-walled aluminum alloy profiles, but it is possible to provide Wellste materials. "Cylinder aluminum extrusion" we strictly control the process of extruding the extrusion speed, the use of CNC machining method, using the hard anodized/powder coating/painting/printing, grinding and other surface treatment and high quality material to produce high quality products.
