Component II: Regularly Questioned Inquiries
1. MOQ: 
CZPTly Min Order Quantity can be 2-three tons/size for tubes with OD below 250mm, and ten tons/dimensions for tubes with OD earlier mentioned 250mm. At times, it depends on steel quality you need to have. If you need to have special quality like E410, E470 or alloy metal tube, MOQ should be ten tons/measurement at minimum. 
2. Delivery Time: CZPTly, our supply time for honed tubes is about forty-sixty times relying on the measurements and portions. It will take us fifteen-30 days to get raw substance. For case in point, if you need 3 tons of little dimension honed tubes 50mm*40mm with roughness of Ra0.25um max, it will just take us at least thirty days to hone this measurement. 
3. Guarantee&Guarantee: Warranty&promise time period is 6 months given that we produce the tubes, and we are not liable for high quality dilemma triggered by wrong unloading or storage after shipment. We welcome customer’s inspection prior to shipment. 
4. Payment Technique: We settle for payment strategy like T/T, L/C, or D/P, but it relies upon on our investigation about buyers. We have a solution to assess the credit score of clients from all more than the globe, and time and sum of D/P we can release is established by the evaluation. 
five. Good quality Management: 90% of the tubes are manufactured from scorching rolled seamless pipes. So, good quality of uncooked substance decided top quality of finished tubes. We obtain uncooked substance from secure suppliers who are top steel mills, and we examine the raw material as per the specs. For the duration of our generation procedure, there is inspection and quality manage in each phase. 

Part III: Firm INTRODUCTION
We are a manufacturer of chilly drawn, cold rolled, and hydraulic cold drawn steel tubes with OD upto 356mm considering that 2002. Masking an region of about 32000M2, we have twelve common workshops with 2 hydraulic chilly drawing benches, 4 chain chilly drawing benches, and 2 ERW mills.
