Q195 Q235 Carbon Steel Round Bar, 10 40 and 60 mm Requirements
Carbon steel round bar has actual length options of 1–12 m and as required. Described diameter is 6–1200 mm, with hot rolled, cold drawn and forged alternatives.
Confirm the exact 10, 40 or 60 mm diameter because no fixed diameter variants are provided. Choose Q195 or Q235 material explicitly; the broader S, SS, A36, A572 and SCM model references are not automatic equivalents. Define the required manufacturing condition and surface.
Black, bright and galvanized finishes are described alternatives requiring selection. No numerical strength, cutting performance or heat treatment result is supplied. A shipbuilding or offshore plate application does not establish marine approval for a round bar. Agree dimensional inspection and material evidence for the selected grade and diameter before fabrication.
