Ametco's Phoenix Design fixed louver aluminum fence and gates were used as a dumpster enclosure at Northwestern University. The Phoenix Design aluminum fence is manufactured from 1/2 x 4 inch extruded aluminum tube. It is recommended that the fixed louver runs horizontally with either 80 or 100 percent direct visual screening. Ametco manufactures dumpster enclosures, equipment enclosures, and gates at our plant in Willoughby, Ohio.
