Quality Standards

Quality Stainless Steel

At Pearce, we understand the rigorous requirements of cleanroom, laboratory & other controlled environments. We use only grades AISI 304, 316, and 316L stainless steel in the fabrication of our products. Designed for use in pharmaceutical and microelectronics manufacturing, our stainless furnishings offer outstanding corrosion resistance, are highly durable and are easy to keep contaminant-free.

Our precision CNC machining, seamless welds, and choice of finishes such as passivation and electro-polishing make Pearce furnishings ideal for the cleanroom environment.

Quality Manufacturing

Pearce uses only certified welders with proven expertise. Our welders strictly follow ASME Section IX specifications and CSA W57 welding procedures.

We utilize Tungsten Inert Gas welding, an electric welding process whereby heat is generated by an electric arc between the end of a non-consumable tungsten electrode and the base metal and shielded by inert gas, as our standard joining process.

Available Finishes

We provide customers with several finishing options. These include:

  • Electro-Polishing

    This is an electro-chemical polishing process that removes a small uniform amount of surface material, producing a smooth, bright and highly reflective finish. Electro-polished stainless steel furnishings are highly corrosion resistant, easier to clean, and effectively defy staining and adhesion.

  • Bead Blasting

    This finish completely removes any surface grain or texture and provides a uniform, smooth satin finish to stainless steel.

  • No. 4 Polish

    This is a general-purpose, mechanically polished finish that yields a fine satin directional grain.

  • 2B Finish

    With a 2B finish on stainless steel, the metal grains are flattened, giving the steel surface a smooth matte appearance.

  • Pickling and Passivation

    Pickling and passivation involves the removal of surface iron from stainless steel using an acid solution (mild oxidant) for the purpose of eliminating corrosion-causing surface contamination. This process encourages the formation of a protective oxide film.
