6063 T5 Architectural Grade Aluminum Square Bar Description
It has processability, excellent workability, and an excellent anodizing effect.
Unlike the structural 6061 alloy, the 6063 Aluminum Square Bar is engineered for aesthetics and surface finish. At GNEE, we specialize in "Architectural Grade" 6063 bars, offering superior extrudability and a flawless surface ideal for anodizing.
Whether you are manufacturing window frames, modular assembly systems, or electronics heat sinks, our 6063 bars ensure precision assembly with sharp corners and zero visible die lines.
Why Choose GNEE's 6063 Square Bars?
Surface Ready for Anodizing:
Our extrusion dies are polished to minimize "die lines." The surface is smooth and uniform, perfect for Clear, Black, or Color Anodizing without streaking.
Sharp Corners (Precision Extrusion):
We know that assembly requires precision.
Standard: Sharp Corners (Radius < 0.5mm) for tight fitting.
Custom: Radius corners are available upon request.
Scratch-Free Packaging:
Interleaving Paper/Film is placed between every layer of bars to prevent friction during ocean freight. Your bars arrive as shiny as they left the factory.

6063-T5 (Air Cooled):
Characteristics: Excellent surface finish, minimal distortion.
Application: Architectural trim, window frames, furniture. (Most Popular)
6063-T6 (Water Cooled):
Characteristics: Higher hardness and strength.
Application: Load-bearing structures, brackets, high-stress fasteners.

Packaging & Shipping
GNEE's Export Standard Packaging for Aluminum Square Rods
We understand that 6063 aluminum is often used for visible architectural parts. A single scratch during sea freight can ruin the value. Therefore, we use a "4-Layer Protection" system:
Interleaving Layer: Paper or Plastic Film is placed between every layer of square bars to prevent friction scratches (Fretting Corrosion).
Moisture Protection: Desiccants are placed inside the package to prevent "White Rust" caused by humidity changes at sea.
Bundle Protection: Bars are wrapped in thick plastic and woven bags, with Edge Protectors on corners.
Wooden Crating: All export orders are loaded into ISPM 15 Fumigated Wooden Cases, secured with steel straps to prevent bending.
Your aluminum bars arrive at your warehouse in the exact same pristine condition as they left our factory.
