D28 tubular series is a system consisting of two basic round profiles and a series of connectors. The tubes and connectors are made of aluminum alloy. The profiles can be easily cut even with a hand-held hacksaw, which makes it possible to quickly rearrange the structure even on site. The D28 system is used in production lines (primarily where manual assembly is involved), as well as in light industry (in the production of electronics, small household appliances or automotive parts).
