The 20 series aluminum strut profile, such as 2020 and 2040, features a 20mm base dimension with a 6mm slot width. It is lightweight (1.5 kg/m) and corrosion-resistant due to sandblasting and silver anodizing. Designed for light-duty structures like equipment shields, small frames, and scientific models, it requires specialized fasteners for assembly and offers modular flexibility but lower load capacity compared to larger series.
