Component II: Regularly Requested Questions
one. MOQ: 
CZPTly Min Purchase Amount can be two-3 tons/measurement for tubes with OD underneath 250mm, and ten tons/dimensions for tubes with OD previously mentioned 250mm. Often, it is dependent on metal grade you want. If you require specific quality like E410, E470 or alloy metal tube, MOQ must be 10 tons/size at minimum. 
2. Shipping and delivery Time: CZPTly, our delivery time for honed tubes is around 40-sixty days based on the measurements and portions. It will consider us 15-30 times to get uncooked material. For illustration, if you need 3 tons of small dimension honed tubes 50mm*40mm with roughness of Ra0.25um max, it will consider us at least thirty times to hone this size. 
3. Warranty&Ensure: Warranty&ensure period of time is 6 months considering that we produce the tubes, and we are not dependable for high quality dilemma induced by improper unloading or storage after cargo. We welcome customer’s inspection prior to cargo.
