JIS H-beams (JIS G3192)

Standard: JIS G3192 (dimensions, mass and tolerances)

Japanese H-sections are designated by nominal depth × flange width (H 300 × 150) and specified by the actual H × B × t1 × t2 — depth, flange width, web thickness and flange thickness. One nominal size often has several weights, which share the inside dimensions and differ in thickness.

The same series is rolled across East and South-East Asia and is widely traded into the GCC. Grades are usually SS400 (JIS G3101) or SM490 (JIS G3106).

H-beam cross-section: depth H (h), flange width B (b), web thickness t1 (tw), flange thickness t2 (tf) and root radius r

Notes

The drawing uses the European letters: H = h, B = b, t1 = tw and t2 = tf.
Plastic moduli are not given for the heaviest 600 × 300 sizes.
