Element II: Usually Asked Queries
1. MOQ: 
CZPTly Min Purchase Amount can be 2-3 tons/measurement for tubes with OD underneath 250mm, and ten tons/measurement for tubes with OD above 250mm. Often, it depends on metal quality you need. If you want particular quality like E410, E470 or alloy steel tube, MOQ need to be 10 tons/size at minimum. 
two. Delivery Time: CZPTly, our shipping and delivery time for honed tubes is around forty-sixty days depending on the measurements and portions. It will consider us fifteen-thirty times to get uncooked content. For instance, if you want 3 tons of little measurement honed tubes 50mm*40mm with roughness of Ra0.25um max, it will consider us at least thirty days to hone this dimensions. 
three. Warranty&Guarantee: Guarantee&promise period of time is 6 months considering that we provide the tubes, and we are not dependable for top quality problem triggered by wrong unloading or storage right after shipment. We welcome customer’s inspection prior to shipment. 
four. Payment Strategy: We settle for payment technique like T/T, L/C, or D/P, but it relies upon on our investigation about consumers. We have a solution to assess the credit score of buyers from all above the entire world, and time and sum of D/P we can release is identified by the analysis. 
5. Good quality Management: ninety% of the tubes are produced from hot rolled seamless pipes. So, good quality of uncooked substance identified top quality of concluded tubes. We obtain uncooked content from stable suppliers who are major metal mills, and we inspect the uncooked materials as for each the requirements. Throughout our generation process, there is inspection and good quality handle in each and every phase. 

We are a manufacturer of cold drawn, cold rolled, and hydraulic chilly drawn metal tubes with OD upto 356mm considering that 2002. Masking an region of about 32000M2, we have twelve regular workshops with 2 hydraulic chilly drawing benches, 4 chain cold drawing benches, and 2 ERW mills. Our services handles all the creation procedures from pickling, chilly drawing, warmth dealing with, saw chopping, straightening, inspection, packing to further machining &turning, cold drawing die fabrication, and products repairation&servicing.
