Solid Shape
Round bars/rods: Cylindrical shapes that can be used in structural applications, as well as for machining parts. Square bars: Used in both structural and decorative applications. Rectangular bars: Often used for framing, support structures, and machine parts.
Hollow
Square tubes: Have applications in construction, architectural projects, and automotive frameworks. Rectangular tubes: Frequently used in structural components for buildings and machinery. Round tubes: Common in plumbing, irrigation, and outdoor equipment like bike frames. Oval and elliptical tubes: Used in aesthetic applications, such as furniture and architectural features.
Semi-Hollow
C-channels: Typically used in construction, framing, or for supporting loads, particularly in the automotive and building industries. Z-sections: Used in cladding, roofing, and structural bracing. I-beams (H-beams): Known for high strength and are widely used in construction and structural framing.
