This 2020 aluminum profile is the standard classic model of the 20 series, featuring a 20×20mm square cross-section design, 6mm slot width, and a 6063-T5 aluminum alloy body with standard anodized surface treatment for a smooth, corrosion-resistant finish. Commonly used for constructing light equipment enclosures, instrument frames, display panels, small door frames, and assembly line barriers, making it one of the most widely used profiles in lightweight frame structures. Matching connections typically use M5 dedicated T-slot nuts and hex socket bolts, providing flexible and reliable connection methods.
