Stainless Steel Polishing Services
Surface finish is an important aspect in any specification of stainless steel regardless of the intended use. For those applications where appearance is important, the surface finish is part of the design elements and must be specified.
At MMA Steel Pte Ltd, we specialize in polishing round pipes and flat bars from their raw forms to satin finishes, in the most cost-efficient way. The process of dull polishing stainless steel pipes and plates involves using an abrasive belt on the surface to change the finish of the metal. Stainless steel pipes and plates supplied from the mill normally come in 1B or 2B finishes. This metal can be polished to achieve a desired finish and the type and direction of polish depends on the abrasive and process used.
Common stainless steel finishes
No. 1 Finish – A no. 1 raw finish after being Cold Rolled, Annealed, Pickled and Passivated. A non reflective, rough, dull, non-uniform appearance. Usually used for industrial applications. Not normally used for decorative applications.
No. 2 Finish – Dull grey slightly reflective finish. This is the general-purpose finish that can be used as is, or a preliminary step to polishing. Typical uses for a standard 2B finish include non-decorative or functional sheet metal products, industrial refrigeration equipment, chemical plant and plumbing fixtures.
No. 4 Finish – Also called brushed, directional or satin finish. A number 4 finish is characterized by fine polishing grit lines that are uniform and directional in appearance. Widely used for restaurant and kitchen equipment, elevators doors, furniture, interior and exterior architectural applications where appearance is important to the design element.
Bright Annealed (BA) – It is shiny and reflective. Applications include ornamental handrails, furniture, interior and exterior architectural applications.
No. 8 Finish – Also known as mirror finish. The most reflective surface of stainless steel available. Normally used for cosmetic applications.
