DSTU 8806:2018 - Cold-formed equal-flange steel channels - Dimensions

Automatically build standard products in SOLIDWORKS with TSFP.

Cold-formed equal-flange steel channels, roll-formed from coil with one wall thickness and rounded bends, unlike hot-rolled channels. ДСТУ 8806:2018 replaces ГОСТ 8278-83 in Ukraine. Steel categories have separate dimension tables, and R is the maximum inner bend radius.
