These beams have flanges in which the planes are nearly parallel. WIDE FLANGE BEAM

In the United States, the most commonly mentioned I-beam is the wide-flange (W) shape.

Other I-beams include American Standard (designated S) shapes, in which flange surfaces are not parallel。

Wide-flange shapes are available in grade ASTM A992,^[4] which has generally replaced the older ASTM grades A572 and A36.

Ranges of yield strength:

A36: 36,000 psi (250 MPa)
A572: 42,000–60,000 psi (290–410 MPa), with 50,000 psi (340 MPa) the most common
A588: Similar to A572
A992: 50,000–65,000 psi (340–450 MPa)
