How to remove powder coating and anodize instead

[1] How to remove powder coating done on Aluminum round tubes. I have asked this question as I want to remove powder coating already applied and now I want to send those tubes for anodizing matte finish.

[2] What surface finishes are available for MS ERW round tubes, so that it will look cosmetically good as well as it will add life of tube.

Dear Mr. Sakhare,

The cheapest method to strip powder coating from Aluminium substrate is dipping coated component in conc. sulfuric acid. Ensure that water does not get mixed in sulfuric.
