Stainless Steel Sheet Various Finishes
Polishing sheet metal can be done in a variety of methods and for various purposes. Some finishes are applied for aesthetic purposes, while others serve to protect delicate components from rust or corrosion. Finishing can sometimes accomplish both goals. Some treatments merely involve changing the metal’s surface, while others involve applying another substance or method to the metal.
Different Finishing Process of SS Sheets
- Brushing: While brushing uses abrasive brushes to clean and score the metal surface, it performs a similar function as sandblasting. It is frequently used as an appliance finish and can be used as a final coat on materials like aluminium and stainless steel.
- Polishing: On metals like copper, aluminium, and stainless steel, polishing produces a glossy finish. It can be used as the last coat of paint or as a base coat before further finishing procedures like plating. Due to the fact that it does not improve adhesion, it is typically inappropriate for metals that will be coated.
- Sand Blasting: Sand blasting is a technique for cleaning and roughening metal surfaces by firing jets of abrasive material at them. In order to eliminate impurities and increase adhesion, sandblasting is frequently used on stainless and carbon steel surfaces before painting.
- Plating: For a variety of purposes, the plating can be done electrolytically or electroless. It can prevent corrosion, enhance solderability, harden a surface, lessen friction, decrease wear, or promote paint adherence. Processes for plating sheet metal include:
Passivation which is a cleaning procedure that keeps stainless steel from corroding by eliminating unbound iron from the material’s surface. - Powder Coating: A thermoplastic or thermoset polymer is often electrostatically applied to the metal surface during powder coating, and the polymer is subsequently heated to cure it. Although the method produces a surface that is more durable than typical paint, it could lack paint’s visual appeal.
