Part II: Often Asked Questions
1. MOQ: 
CZPTly Min Purchase Amount can be 2-3 tons/dimensions for tubes with OD underneath 250mm, and ten tons/measurement for tubes with OD over 250mm. Often, it is dependent on metal grade you want. If you want special quality like E410, E470 or alloy steel tube, MOQ must be 10 tons/size at minimum. 
two. Delivery Time: CZPTly, our supply time for honed tubes is close to 40-sixty days dependent on the measurements and quantities. It will consider us fifteen-30 times to get uncooked substance. For example, if you want 3 tons of tiny dimension honed tubes 50mm*40mm with roughness of Ra0.25um max, it will get us at minimum 30 times to hone this size. 
three. Warranty&Promise: Warranty&ensure period of time is 6 months because we supply the tubes, and we are not liable for high quality difficulty caused by mistaken unloading or storage soon after cargo. We welcome customer’s inspection prior to cargo. 
4. Payment Method: 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 evaluate the credit history of consumers from all in excess of the world, and time and sum of D/P we can launch is established by the evaluation. 
5. Good quality Management: 90% of the tubes are produced from sizzling rolled seamless pipes. So, quality of uncooked content determined good quality of finished tubes. We purchase uncooked material from steady suppliers who are leading metal mills, and we examine the raw material as per the requirements. Throughout our creation procedure, there is inspection and good quality control in each phase. 

We are a manufacturer of cold drawn, chilly rolled, and hydraulic cold drawn metal tubes with OD upto 356mm because 2002. Masking an area of about 32000M2, we have twelve common workshops with 2 hydraulic cold drawing benches, 4 chain cold drawing benches, and 2 ERW mills. Our facilities handles all the creation procedures from pickling, cold drawing, heat dealing with, saw cutting, straightening, inspection, packing to more machining &turning, cold drawing die fabrication, and gear repairation&routine maintenance.
