Large Shiny Stainless Steel Ball
Stainless Steel Hollow Ball:
Manufacturing Procedure:
Step 1: Selection of Size and Preparation
High quality stainless steel is applied in the construction procedure, where we usually use standard AISI/SS 304 Stainless Steel due to its comparatively high cost-effectiveness and practicability among 201 and 316.
After the preparatory process, stainless steel sheet will be cut, bent and shaped into a preliminary "sphere".
Step 2: Polishing
This "sphere" is not spherical though. It is however angular which has to be rounded first after a serial of compulsory procedures.
Step 3: Refining
By using several tools and materials, the surface of the sculpture is mirror-polished to flawlessness.
Step 4: Packing
Specifically-tailored wooden box will keep the sculpture safe and intact during transport.
