Steel Structural Shapes - I-Beam, Channel & Round Bar Diagram #176566 (License: Personal Use)

This vector illustration depicts three fundamental steel structural profiles: a wide-flange I-beam at the center, flanked by C-shaped channels, with two round bars positioned beneath. The clean linework and shading emphasize cross-sectional geometry and dimensional relationships critical for load-bearing design in buildings, bridges, and industrial frameworks.

Used on engineering education sites, manufacturer catalogs, or construction resource pages to explain structural steel types; matches user intent for learning about beam selection, material specs, or drafting standards.
