Portion II: Frequently Questioned Concerns
1. MOQ: CZPTly Min Purchase Quantity can be two-three tons/measurement for tubes with OD under 250mm, and 10 tons/size for tubes with OD over 250mm. Occasionally, it is dependent on metal grade you want. If you need particular quality like E410, E470 or alloy steel tube, MOQ ought to be 10 tons/measurement at the very least.
2. Supply Time: CZPTly, our delivery time for honed tubes is all around 40-sixty times relying on the dimensions and quantities. It will consider us 15-30 times to get raw substance. For example, if you need to have 3 tons of little measurement honed tubes 50mm*40mm with roughness of Ra0.25um max, it will take us at least thirty times to hone this dimension.
three. Warranty&Assure: Guarantee&guarantee time period is 6 months since we supply the tubes, and we are not accountable for high quality problem induced by wrong unloading or storage after cargo. We welcome customer’s inspection prior to shipment.
four. Payment Method: We take payment technique like T/T, L/C, or D/P, but it relies upon on our investigation about consumers. We have a solution to appraise the credit score of consumers from all above the world, and time and quantity of D/P we can launch is identified by the evaluation.
5. Top quality Handle: ninety% of the tubes are manufactured from hot rolled seamless pipes. So, top quality of uncooked material established quality of finished tubes. We purchase raw substance from stable suppliers who are foremost metal mills, and we examine the raw content as per the specifications. For the duration of our manufacturing procedure, there is inspection and quality control in every single stage.
