澳大利亚采购需求：气缸管

I'm looking for detailed specifications and pricing for a 100mm diameter Bore Aluminum Pneumatic Cylinder tubing. Could you provide information on your minimum order quantity? Additionally, I'd like to know more about the internal finish—are these honed? Also, what type of surface finish can I expect, particularly for the bore? Importantly, I want to confirm if the material can be anodized after you've supplied and machined it. This info will help me move forward with our project. Looking forward to your prompt response!
