6 Inch Mirror Polished Stainless Steel Hemisphere with M4 Female Thread
|| INSIDE OUR COMPANY AND STAINLESS STEEL SPHERE ||
Our company is located in the southeast China ,which enjoyes convinient domestic and international transport. For a decade, we have become a reliable supplier to customers worldwide, mostly manufacturing and providing all sizes of stainless steel spheres/balls, hemispheres and other stainless steel-related items, such as indoor and outdoor decorative items, handrails and certain accessories.
For stainless steel balls, they are usually divided into few categories with different grits/polishes. As to different grirts, it means differnent unit price, besides quantity, the most critical factor in determing price.
Stainless steel hollow hemispheres are handcrafted, thus there will be no identifcal sphere. They are not perfectly round or flawless either.

Packaging & Shipping
Thick and standard wooden case with metal junction and nails. Pallet on the bottom.
Thick plastic or soft shockproof foam to avoid scratches on the surface of the product;
Cushioning tire on the bottom to prevent the item moving or tumbling or leaving dents on the product in case of rough transport.
Modes of Shipment
Ground, Ship and Air
Land or "ground" shipping can be by train or by truck. Ground transport is typically more affordable than air, but more expensive than sea especially in developing countries like India, where inland infrastructure is not the most effective way.
Shipment of cargo by trucks, directly from the shipper's place to the destination, is known as a door to door shipment and more formally as multimodal transport. Trucks and trains make deliveries to sea and air ports where cargo is moved in bulk.
Cargo was transported by air in specialized cargo aircraft and in the luggage compartments of passenger aircraft. Air freight is typically the fastest mode for long distance freight transport, but also the most expensive.
