Square Bar (Radiused): 1/4" Width x 1/4" Thickness - 1/16" Radius - 6063-T5 Aluminum Product Information

Aluminum Radiused Square Bars feature a solid square profile with softened, rounded corners, combining structural strength with improved handling and a refined appearance. Often specified as radiused square aluminum bar stock, these extrusions are used in structural, architectural, and fabrication applications where sharp edges are undesirable.

The radiused corners reduce edge sharpness while maintaining the strength and clean geometry of a square bar. This makes radiused square bars easier to handle, safer in exposed applications, and well-suited for machining, cutting, drilling, tapping, and welding. Manufactured from corrosion-resistant aluminum, they perform reliably in both indoor and outdoor environments.

Highlights

• Radiused Square Aluminum Bar Stock – Square profile with rounded corners for safer handling and cleaner finishes.
• Improved Edge Profile – Reduced sharp edges ideal for exposed, touch-facing, or decorative applications.
• Strong, Lightweight Aluminum – Excellent strength-to-weight ratio for structural and functional builds.
• Fabrication Friendly – Easily cut, drilled, tapped, welded, or machined to meet project requirements.
• Corrosion Resistant – Suitable for interior, exterior, and high-humidity environments.
• Versatile Across Industries – Commonly used in architectural frameworks, equipment frames, guards, fixtures, and custom fabrication projects.
