Processing Flow
Jinling produces No.4 brushed stainless steel sheet and coil from stable 2B substrate through surface pre-treatment, continuous belt grinding, grit refinement, optional Scotch-Brite satin finishing, and quality inspection. This controlled No.4 finish process helps buyers receive uniform linear grain, consistent satin reflection, and fabrication-ready brushed stainless steel panels for elevators, appliances, architectural interiors, and OEM projects.
- 01
2B Substrate Preparation
No.4 finish normally starts from cold rolled, annealed, pickled, skin-passed 2B stainless steel for a flat and stable base.
- 02
Surface Pre-Treatment
Oil, dust, scratches, and roll marks are checked and removed before grinding to improve brushed stainless steel consistency.
- 03
Continuous Belt Grinding
Abrasive, emery, or Scotch-Brite belts grind in one direction to create the ASTM A480-style linearly textured No.4 finish.
- 04
Grit Refinement
150#, 180#, 240#, and 320# options support coarse No.4, standard No.4, fine satin, and super satin requirements.
- 05
Scotch-Brite Finishing
Optional Scotch-Brite treatment softens the grain, evens reflection, and reduces belt marks for elevator and architectural panels.
- 06
Quality Inspection
Grain consistency, directionality, surface roughness Ra, color difference, and scratches are checked before protective film application.
