H-Beam STEP Files

Hot-rolled H-beams to KS D 3502 with full section geometry (H, B, web/flange thickness, fillet r). For steel-frame layout, connection detailing, and take-off models.

Free 3D CAD models (STEP AP214). Built to real standard dimensions; threads are simplified (plain shank) per free-library convention.

Standard: KS D 3502

Using these STEP files in CAD

STEP AP214 format opens directly in SolidWorks, Inventor, Fusion, CATIA, NX, FreeCAD, and most CAD systems.
Per free-library convention, threads are not modeled (plain shank). These are for layout, clearance, and drawings — not fastening simulation.
All dimensions use the standard's nominal values. For tolerance-critical use, check the allowances in the spec table.
