Component II: Frequently Asked Questions
1. MOQ: 
CZPTly Min Purchase Amount can be two-3 tons/measurement for tubes with OD below 250mm, and 10 tons/measurement for tubes with OD over 250mm. Sometimes, it is dependent on steel quality you need to have. If you need particular grade like E410, E470 or alloy metal tube, MOQ must be ten tons/size at the very least. 
2. Delivery Time: CZPTly, our delivery time for honed tubes is about 40-60 times based on the sizes and portions. It will consider us 15-thirty days to get uncooked materials. For case in point, if you need 3 tons of little size honed tubes 50mm*40mm with roughness of Ra0.25um max, it will consider us at minimum thirty days to hone this dimension. 
three. Guarantee&Guarantee: Guarantee&ensure period is 6 months given that we provide the tubes, and we are not responsible for good quality dilemma caused by incorrect unloading or storage after shipment. We welcome customer’s inspection prior to cargo. 
four. Payment Approach: We settle for payment approach like T/T, L/C, or D/P, but it is dependent on our investigation about buyers. We have a solution to assess the credit history of customers from all over the planet, and time and amount of D/P we can release is decided by the analysis. 
5. Top quality Manage: 90% of the tubes are produced from sizzling rolled seamless pipes. So, good quality of uncooked substance decided quality of concluded tubes. We obtain raw substance from secure suppliers who are leading steel mills, and we inspect the raw material as for every the technical specs. In the course of our production procedure, there is inspection and high quality manage in each stage.
