   "Aluminum tee bar is mostly sold as 6063-T52 'architectural tee' in 1/8 in thickness and as 6061-T6 structural tee. Continental Steel lists four 6063-T52 items (3/4 x 3/4, 1 x 1, 1-1/4 x 7/8, 2 x 3/4, all 1/8 in thick, 16 ft stock) with an estimated weight per foot and states sharp inside and outside corners. Alcobra Metals lists 3/4 x 3/4 x 1/8 and 1 x 1 x 1/8 (6063-T52) and 1-1/2 x 1-1/2 x 1/8 (6063-T5); the 1 x 1 x 1/8 page names ASTM B221 and lengths of 12 to 94 in. Metals4U and Online Metals list 1 x 1 x 1/8, 1-1/2 x 1-1/8 and a 6061-T6 1-1/2 x 1-1/2 x 1/4. The two dimension sources agree on the sizes they share. The Aluminum Association also publishes structural tees (with stem radii and taper); no table of them was read, so those are not covered.",
   "Check: a tee of flange width W, height H and uniform thickness t has area W t + (H − t) t. Recomputed at 0.0975 lb/in³ (aluminum 2.70 g/cm³) the weights come within 1 % of Continental's printed weights for all four sizes, which confirms the flange and stem are the same thickness and the corners are sharp (no radius adds area).",
   "The sources print sizes as 'A x B x t' and the two numbers cannot be told apart by weight alone (a 2 x 3/4 and a 3/4 x 2 tee have the same area). Industrial Metal Supply's tee page defines W (width), H (height) and T (thickness) in a diagram but its sizes are in an image. So only the two square tees are drawn; the 1-1/4 x 7/8 and 2 x 3/4 sizes are numbers only.",
