Part II: Frequently Requested Inquiries
1. MOQ: CZPTly Min Order Amount can be 2-three tons/dimension for tubes with OD under 250mm, and 10 tons/dimension for tubes with OD above 250mm. Occasionally, it relies upon on steel quality you need to have. If you want special quality like E410, E470 or alloy steel tube, MOQ must be 10 tons/dimensions at the very least. 
two. Shipping and delivery Time: CZPTly, our shipping time for honed tubes is about forty-60 days depending on the sizes and portions. It will consider us fifteen-30 days to get raw materials. For example, if you require 3 tons of small dimension honed tubes 50mm*40mm with roughness of Ra0.25um max, it will just take us at minimum thirty times to hone this size. 
3. Warranty&Ensure: Guarantee&guarantee period is 6 months since we produce the tubes, and we are not liable for high quality problem triggered by wrong unloading or storage soon after shipment. We welcome customer’s inspection before shipment. 
4. Payment Method: We acknowledge payment approach like T/T, L/C, or D/P, but it depends on our investigation about buyers. We have a solution to appraise the credit history of customers from all above the globe, and time and amount of D/P we can release is established by the analysis. 
5. Top quality Handle: ninety% of the tubes are produced from hot rolled seamless pipes. So, good quality of raw material decided top quality of completed tubes. We obtain uncooked substance from secure suppliers who are major metal mills, and we inspect the uncooked substance as for every the technical specs. For the duration of our generation process, there is inspection and good quality handle in each and every stage.
