For our textile printers we use the 1.5" profile that hold up very well. Our aluminum frames  are manufactured with welded corners for the best screen-printing stability. Each frames corners are completely sealed to prevent any possible leaks during the cleaning process.  We also sand one side of our frames to insure the best possible results during the fabric adhesion process. Our aluminum frames hold up to water and solvents without any concern of warping or distortion. With aluminum frames you can expect a long, trouble free screen life.
