• 6063 Square Aluminum Profile: Al-Mg-Si alloy with outstanding extrusion performance, fine and uniform surface texture, excellent anodizing, spraying and coloring effect. Moderate strength, good toughness and cost performance, ideal for decoration, furniture structure and conventional industrial frames.
• 6061 Square Aluminum Profile: Heat-treatable high-strength alloy, balanced tensile strength, hardness and machinability. Higher load-bearing capacity and structural rigidity, perfect for high-precision mechanical parts, automation equipment and heavy-duty support structures.
• Virgin Raw Material: Made of high-purity primary aluminum ingot, low impurity content, compact internal grain structure, no pores, no inclusions, stable chemical composition and consistent batch quality.

• Adopt precision hot extrusion forming process, dense internal organization, strong compression resistance and impact resistance.
• High straightness and right-angle verticality of square profile, no distortion, no bending, neat edge angle.
• Uniform wall thickness, strict dimensional tolerance on side width, height and wall thickness, fully meet precision assembly and splicing requirements.
• Stable internal stress treatment, not easy to deform after cutting, drilling and assembling.

• Smooth flat surface with no burrs, scratches, oxidation spots or defects.
• Excellent surface uniformity, suitable for anodizing, electrophoresis, powder coating, fluorocarbon spraying, polishing and wood grain transfer.
• Good texture and high appearance grade, can be directly applied to visible decorative and exposed structural parts without secondary grinding.

• Lightweight & High Rigidity: Low density, light weight for easy handling, transportation and installation; maintain high structural rigidity to reduce overall project load and construction cost.
• Super Corrosion & Weather Resistance: Great anti-oxidation, rust-proof and salt spray resistance. Adapt to indoor, outdoor, humid and coastal environments, long service life with low maintenance.
