Portion II: Often Questioned Inquiries
1. MOQ: CZPTly Min Order Quantity can be two-3 tons/size for tubes with OD under 250mm, and ten tons/size for tubes with OD previously mentioned 250mm. Occasionally, it is dependent on metal quality you need. If you want special grade like E410, E470 or alloy metal tube, MOQ need to be ten tons/dimensions at least.
two. Shipping and delivery Time: CZPTly, our shipping and delivery time for honed tubes is about forty-sixty times dependent on the dimensions and portions. It will get us 15-30 days to get raw content. For instance, if you need 3 tons of small measurement honed tubes 50mm*40mm with roughness of Ra0.25um max, it will just take us at minimum thirty days to hone this size.
three. Guarantee&Ensure: Warranty&assure period is 6 months considering that we deliver the tubes, and we are not accountable for quality difficulty triggered by incorrect unloading or storage following shipment. We welcome customer’s inspection just before cargo.
four. Payment Method: We acknowledge payment approach like T/T, L/C, or D/P, but it relies upon on our investigation about clients. We have a solution to consider the credit history of buyers from all above the world, and time and sum of D/P we can release is decided by the analysis.
5. Top quality Handle: 90% of the tubes are produced from very hot rolled seamless pipes. So, quality of raw content identified top quality of finished tubes. We buy raw materials from stable suppliers who are leading metal mills, and we inspect the raw content as for every the specs. In the course of our manufacturing procedure, there is inspection and high quality manage in every stage.
Part III: Organization INTRODUCTION
We are a manufacturer of cold drawn, chilly rolled, and hydraulic cold drawn metal tubes with OD upto 356mm considering that 2002. Covering an spot of about 32000M2, we have twelve regular workshops with 2 hydraulic cold drawing benches, 4 chain chilly drawing benches, and 2 ERW mills. Our facilities addresses all the generation processes from pickling, cold drawing, warmth managing, observed chopping, straightening, inspection, packing to additional machining &turning, chilly drawing die fabrication, and gear repairation&maintenance.
