3.

Next, I would like to introduce the steel you are interested.

Generally speaking, we can provide

Hot-rolled steel bar: diameter/side length: 16mm-300mm

Forged bar:        diameter/side length: 150mm-800mm

Cold-drawn steel bar: diameter/side length:≤50mm

The size tolerances of hot-rolled steel bar on our standard conform to the tables in the attachment.

You can also send us your standard if you want more precise products.
