⚙️ 20 mm steel round bar - heavy-duty axles, kingpins, and heavy forging
20 mm steel round bar is hot-rolled long product between small turning stock and heavy-duty structural metal. At almost 2.5 kg per metre, it is a cross-section for load-bearing parts such as trailer kingpins, wheel axles, and hinge pins for machinery. Grades 20 and 45 structural steel are available for demanding machining applications.
🏗️ Main applications:
- Heavy-duty axles and kingpins: connecting pins for trailers, attachments, and heavy machinery.
- Loaded shafts: drive and support shafts made from grade 45 steel and hardened.
- Heavy hot forging: massive fence elements, balusters, and forged components.
