Component II: Often Requested Questions
one. MOQ: CZPTly Min Get Quantity can be 2-3 tons/dimensions for tubes with OD beneath 250mm, and 10 tons/dimensions for tubes with OD over 250mm. Sometimes, it relies upon on steel quality you need to have. If you need to have special quality like E410, E470 or alloy steel tube, MOQ ought to be 10 tons/measurement at least.
2. Delivery Time: CZPTly, our shipping and delivery time for honed tubes is around forty-sixty times dependent on the sizes and quantities. It will take us fifteen-30 days to get uncooked substance. For illustration, if you require 3 tons of modest dimensions honed tubes 50mm*40mm with roughness of Ra0.25um max, it will take us at minimum 30 times to hone this measurement.
3. Guarantee&Ensure: Warranty&assure period is 6 months because we produce the tubes, and we are not responsible for quality dilemma caused by improper unloading or storage right after shipment. We welcome customer’s inspection before shipment.
4. Payment Strategy: We accept payment technique like T/T, L/C, or D/P, but it is dependent on our investigation about consumers. We have a solution to assess the credit history of buyers from all over the planet, and time and volume of D/P we can launch is identified by the analysis.
five. Quality Manage: 90% of the tubes are made from scorching rolled seamless pipes. So, high quality of uncooked materials identified quality of completed tubes. We buy raw content from stable suppliers who are foremost steel mills, and we inspect the uncooked content as per the specs. Throughout our manufacturing method, there is inspection and high quality control in each stage.
