What’s the difference between Structural and Bar Stock?

Structural Steel vs Bar Stock

Feature Structural Steel Bar Stock
Primary Use Load-bearing, support, construction Machining, fabrication, components
Common Shapes Beam, Channel, Angle Flat, Round, Square
Strength Focus Designed for structural loads Material strength varies by application
Precision Standard tolerances Available in tight tolerances (CF)
Surface Finish Mill scale, rougher finish Smooth (cold finished) or scaled (hot rolled)
Typical Work Frames, buildings, supports Shafts, brackets, plates, parts
Fabrication Weld, bolt, assemble Cut, machine, drill, weld
