Portion II: Frequently Questioned Inquiries
one. MOQ: 
CZPTly Min Buy Amount can be two-3 tons/dimensions for tubes with OD under 250mm, and 10 tons/dimension for tubes with OD previously mentioned 250mm. Often, it is dependent on metal grade you need to have. If you need special quality like E410, E470 or alloy steel tube, MOQ must be ten tons/dimensions at least. 
2. Shipping and delivery Time: CZPTly, our supply time for honed tubes is around 40-60 times based on the dimensions and portions. It will consider us fifteen-30 days to get raw content. For illustration, if you require 3 tons of little dimension honed tubes 50mm*40mm with roughness of Ra0.25um max, it will take us at minimum thirty days to hone this measurement. 
three. Warranty&Assure: Guarantee&ensure interval is 6 months considering that we produce the tubes, and we are not accountable for quality problem induced by wrong unloading or storage following shipment. We welcome customer’s inspection before shipment.
