No Flange Channel Screed
Flannery’s No Flange Channel Screeds create an aesthetic reveal in any stucco wall system. Channel Screeds break up plaster or stucco walls by creating horizontal and vertical reveal lines. No Flange Channel Screeds are unique in that they come without the traditional attachment flanges. By removing the flanges from the channel screed, it reduces the amount of raw aluminum used in the production of the trim, which reduces the overall cost. Flannery’s No Flange Channel Screeds are also available with fastening clips at an additional charge.
Flannery’s No Flange Channel Screeds are standard extruded aluminum alloy 6063 T5 and have a .050” nominal wall thickness. Aluminum Plaster trims come in 10′ lengths and shall have a standard Clear Anodized Finish. Mill Finish (for field priming & painting), Chem-film finish or other factory finishes and custom paint orders are available. Click on Info Tab above for Factory Finishes.

Flannery offers prefabricated intersections and corners for intricate building designs that utilize intersecting lines and bands on exterior walls. Prefabricated intersections and corners are mitered and then welded together at their attachment flanges, then vinyl tape is applied to the back of the reveal to prevent water intrusion.
