Weights come only from Metals Depot. A 1-5/16 in size is listed by Online Metals without an across-flats value; it is shown from its name.",
   "Flat bar: Continental Steel's hot rolled flat bar list (A36, square edge, 20 ft lengths) has 280 sizes; only the first 25 were readable, all 1/8 in and 3/16 in thick. Rows below are those, plus Online Metals' 3/8 x 3 in (3.84 lb/ft). Continental's page has two apparent typos: 1/8 x 1 is printed 4.250 lb/ft (its own 20 ft weight, 8.50 lb, gives 0.425, which is used) and 3/16 x '1 5/8' has the decimal 1.375 and the weight of a 1-3/8 in bar, so that row is omitted. Steel weighs about 3.4 lb per foot per square inch of section, which reproduces the listed weights to rounding.",
   "Most distributors cut flat bar to length; Online Metals states custom cuts up to 240 in. Other widths and thicknesses (1/4, 3/8, 1/2 in and up to 12 in wide) exist in the 280-size list but were not readable.",

Steel weighs about 3.4 lb per foot per square inch of section, which reproduces the listed weights to rounding.\n- Most distributors cut flat bar to length; Online Metals states custom cuts up to 240 in. Other widths and thicknesses (1/4, 3/8, 1/2 in and up to 12 in wide) exist in the 280-size list but were not readable.\n- Aluminum and stainless flat bar are on their own pages (aluminum-flat-bar-and-round-bar-sizes, stainless-steel-round-and-flat-bar-sizes); round and square steel bar on bar-stock-sizes-round-square-steel-aluminum.\n- No files: a flat bar is a rectangle and a hex bar a prism, which a table already describes at every size and length.\n\nshape  size  decimal, in  mm  weight, lb/ft  source\nhex 1018 cold finished  1/4 in AF  0.2500  6.35  0.20  Online Metals + Metals Depot\nhex 1018 cold finished  5/16 in AF  0.3125  7.94  0.30  Online Metals + Metals Depot\nhex 1018 cold finished  3/8 in AF  0.3750  9.52  0.42  Online Metals + Metals Depot\nhex 1018 cold finished  7/16 in AF  0.4375  11.11  0.60  Online Metals + Metals Depot\nhex 1018 cold finished  1/2 in AF  0.5000  12.70  0.74  Online Metals + Metals Depot\nhex 1018 cold finished  5/8 in AF  0.6250  15.88  1.15  Online Metals + Metals Depot\nhex 1018 cold finished  11/16 in AF  0.6875  17.46  1.39  Online Metals + Metals Depot\nhex 1018 cold finished  3/4 in AF  0.7500  19.05  1.66  Online Metals + Metals Depot\nhex 1018 cold finished  7/8 in AF  0.8750  22.22  2.25  Online Metals + Metals Depot\nhex 1018 cold finished  1 in AF  1.0000  25.40  2.94  Online Metals + Metals Depot\nhex 1018 cold finished  1-1/8 in AF  1.1250  28.57  3.75  Online Metals + Metals Depot\nhex 1018 cold finished  1-1/4 in AF  1.2500  31.75  —  Online Metals\nhex 1018 cold finished  1-5/16 in AF  1.3125  33.34  —  Online Metals\nhex 1018 cold finished  1-1/2 in AF  1.5000  38.10  —  Online Metals\nhex 1018 cold finished  1-3/4 in AF  1.7500  44.45  —  Online Metals\nhex 1018 cold finished  2 in AF  2.0000  50.80  12.00  Online Metals + Metals Depot\nhex 1018 cold finished  5 mm AF  0.1969  5  —  Online Metals (60 in length)\nhex 1018 cold finished  6 mm AF  0.2362  6  —  Online Metals (60 in length)\nhex 1018 cold finished  7 mm AF  0.2756  7  —  Online Metals (60 in length)\nhex 1018 cold finished  8 mm AF  0.3150  8  —  Online Metals (60 in length)\nhex 1018 cold finished  10 mm AF  0.3937  10  —  Online Metals (60 in length)\nhex 1018 cold finished  12 mm AF  0.4724  12  —  Online Metals (60 in length)\nhex 1018 cold finished  13 mm AF  0.5118  13  —  Online Metals (60 in length)\nhex 1018 cold finished  15 mm AF  0.5906  15  —  Online Metals (60 in length)\nhex 1018 cold finished  18 mm AF  0.7087  18  —  Online Metals (60 in length)\nflat bar A36 hot rolled  1/8 x 1/2 in  0.1250 x 0.5000  3.17 x 12.70  0.213  Continental Steel\nflat bar A36 hot rolled  1/8 x 5/8 in  0.1250 x 0.6250  3.17 x 15.88  0.266  Continental Steel\nflat bar A36 hot rolled  1/8 x 3/4 in  0.1250 x 0.7500  3.17 x 19.05  0.319  Continental Steel\nflat bar A36 hot rolled  1/8 x 1 in  0.1250 x 1.0000  3.17 x 25.40  0.425  Continental Steel (page prints 4.250;
