We fabricate PVC elbows in sizes up to 24' diameter from extruded PVC or CPVC duct. All pvc ductwork over 24' diameter is fabricated from Type II or Type I extruded PVC sheet. Longitudinal joints are joined together with a Wegener automatic butt welding machine. Our method of reinforcing often exceeeds SMACNA specifications. Square to round transitions are heat-formed over a cardboard form (no cold breaking), trimmed and welded together. This method insures a stronger part while providing a more efficient, smoother airflow. Rectangular duct corners are heat formed on an automatic strip heating machine. All parts are cut on a 4' x 8' CNC router for precise fit.
