Please note: Black mild steel round bar is supplied in an as-rolled condition and is not precision finished. As a result, variations in diameter, roundness and surface finish can occur during manufacturing. If your application requires a consistent, accurately controlled diameter, we recommend using our bright mild steel round bar, which is manufactured to tighter dimensional tolerances.
Our 25mm mild Steel round bar is available in 3 m and 6 m lengths as standard, or can be supplied in custom cut lengths up to 6 m with the metals4U free custom cutting service.

- Is black mild steel truly black in colour?
- Will this pole dip in the middle if I attach it to 2 ceiling brackets to hold a large curtain on a 110in long window?
