Part II: Usually Asked Questions
1. MOQ: CZPTly Min Get Amount can be 2-3 tons/measurement for tubes with OD under 250mm, and ten tons/size for tubes with OD earlier mentioned 250mm. Sometimes, it depends on steel grade you want. If you need special grade like E410, E470 or alloy steel tube, MOQ must be ten tons/dimension at the very least.
two. Delivery Time: CZPTly, our delivery time for honed tubes is around forty-60 days based on the dimensions and quantities. It will get us fifteen-thirty times to get raw content. For example, if you want 3 tons of small measurement honed tubes 50mm*40mm with roughness of Ra0.25um max, it will consider us at minimum 30 times to hone this dimension.
3. Guarantee&Promise: Warranty&ensure interval is 6 months since we supply the tubes, and we are not liable for high quality dilemma triggered by incorrect unloading or storage soon after cargo. We welcome customer’s inspection before shipment.
4. Payment Approach: We accept payment method like T/T, L/C, or D/P, but it relies upon on our investigation about buyers. We have a solution to consider the credit history of customers from all above the planet, and time and amount of D/P we can release is identified by the evaluation.
5. Top quality Handle: ninety% of the tubes are manufactured from very hot rolled seamless pipes. So, good quality of raw materials established top quality of finished tubes. We acquire raw substance from secure suppliers who are major metal mills, and we examine the uncooked materials as for each the technical specs. During our creation method, there is inspection and quality handle in each and every stage.
