Part II: Often Questioned Questions
one. MOQ: CZPTly Min Get Quantity can be two-three tons/dimension for tubes with OD under 250mm, and 10 tons/measurement for tubes with OD previously mentioned 250mm. Occasionally, it depends on metal grade you require. If you need specific quality like E410, E470 or alloy metal tube, MOQ ought to be ten tons/dimension at minimum.
two. Shipping and delivery Time: twenty-30 days dependent on ordered dimensions and portions.
three. Guarantee&Ensure: Guarantee&guarantee period is 6 months because we supply the tubes, and we are not liable for high quality problem brought on by improper unloading or storage right after shipment. We welcome customer’s inspection just before shipment.
