Structural Steel Spec Table
6 types of spec data
Structural steel — including H-beams, I-beams, angles, channels, and CT sections — achieves high structural rigidity through cross-sectional geometry. Widely used in building steel frames, industrial equipment structures, and machine bases. KS D 3502 (SS400) is the most common standard; section modulus selection based on load and span is critical.

Frequently Asked Questions
What does H200×100×5.5×8 beam notation mean?
Height 200mm, flange width 100mm, web thickness 5.5mm, flange thickness 8mm.
What is the second moment of area (I) used for in structural steel?
It is used to calculate bending stiffness and deflection of beams. Higher I values mean greater resistance to bending.
