Premium ASTM material 6063-T5 aluminum alloy has excellent corrosion resistance and is easy to process, allowing it to meet various appearance and size requirements.

Precision extruding the aluminum profile has high strength and durability, conforming to European standard, and can be freely assembled as needed.

The anodizing process enhances the durability and lifespan of metal, increases metal hardness, and creates a smooth metal surface.

Professional cutting ensures a small tolerance range of ±0.5 mm, a smooth edge without burr, and precise dimensions.
