Cold Rolled Mild Steel Tube | CR250

Cold Rolled Mild Steel Tube | CR250 Specifications

New Zealand made, manufactured from Australian made, high grade cold rolled and batch-annealed steel coil.

CR250 tube provides an exceptional surface finish, superior dimensional accuracy, and a high level of formability across a wide range of thinner walled profiles.
Well suited to furniture components, healthcare, lightweight frames, brackets, and fabricated assemblies that depend on predictable formability, accurate fit-up, and stable dimensions to support efficient downstream manufacturing.
As an uncoated product, it is perfect for finishing processes such as powder coating, high-gloss painting, zinc and chrome plating.
