德国采购需求：气缸管

I'm reaching out regarding your profile with a diameter of 125 mm. I'm currently planning to construct two pressure vessels and have a specific interest in this profile for the project. Could you confirm if it's possible to order shorter cut pieces, like 250 mm in length? Additionally, do you offer STEP files or any technical drawings for this profile? Your assistance on these points would be greatly appreciated. Looking forward to your prompt response!
