Steel angles L (AISC): L4x4x1/4, L3x3x1/4, L2x2x1/4, L5x3x1/4 dimensions + STEP/STL

What are the dimensions of an L4x4x1/4 steel angle? · Standard part · basis: AISC Shapes Database (v15.0 values): d, b, t, k for every equal and unequal angle

Also called: l4x4x1/4, l 4 x 4 x 1/4, l4x4x1/4 dimensions, l2x2x1/4, l2x2x1/4 dimensions, l3x3x1/4, l3x3x3/8, l5x3x1/4, l6x4x1/2, l6x6x1/2, l8x8x1/2, l3-1/2x3-1/2x1/4, angle iron dimensions, steel angle dimensions, angle iron step file, equal angle dimensions, unequal angle dimensions, angle iron sizes

Exact dimensions. True size, with no printing tolerance added.

Notes

  • Single angles L(long leg) x (short leg) x thickness: L4x4x1/4 has two 4 in legs 1/4 in thick, L5x3-1/2x3/8 a 5 in leg and a 3-1/2 in leg. The long leg is d and the short leg b in the AISC database; both legs have the same thickness t.
  • The thickness is taken from the designation (the database prints it rounded to two decimals). The root fillet is not printed: it is derived from the printed k (back of the leg to the toe of the fillet), r = k - t. The toe radius is not printed either, so toes are square.
  • The files put the heel at the origin: the long leg runs along +y, the short leg along +z. 4 in (101.6 mm) long. Drawn area is within 4 % of the printed area on all of them.
  • 31 of the 137 sizes (equal and unequal) have files; all sizes are in the table.
