Element II: Frequently Requested Concerns
one. MOQ: CZPTly Min Order Amount can be 2-3 tons/size for tubes with OD below 250mm, and 10 tons/size for tubes with OD over 250mm. Sometimes, it depends on metal grade you need. If you need particular quality like E410, E470 or alloy metal tube, MOQ ought to be 10 tons/size at least.
2. Shipping and delivery Time: CZPTly, our shipping time for honed tubes is close to 40-60 times depending on the dimensions and portions. It will consider us 15-thirty times to get raw material. For case in point, if you need 3 tons of tiny dimension honed tubes 50mm*40mm with roughness of Ra0.25um max, it will get us at the very least thirty times to hone this dimensions.
three. Warranty&Assure: Guarantee&assure interval is 6 months considering that we deliver the tubes, and we are not liable for top quality problem brought on by mistaken unloading or storage following shipment. We welcome customer’s inspection before cargo.
4. Payment Strategy: We take payment method like T/T, L/C, or D/P, but it depends on our investigation about buyers. We have a solution to appraise the credit rating of clients from all over the globe, and time and amount of D/P we can release is identified by the evaluation.
five. Quality Management: ninety% of the tubes are created from hot rolled seamless pipes. So, quality of raw substance established quality of completed tubes. We acquire raw content from stable suppliers who are leading metal mills, and we examine the raw materials as for every the requirements. During our generation process, there is inspection and high quality manage in each stage.
