As-Fabricated (Raw / Mill Finish)

Passivation process

Default finish straight from sheet metal fabrication cutting, bending, and welding with no secondary treatment. Visible shear cut edges, bend lines, weld seams, and native mill finish. Suitable for structural brackets, internal frames, and functional components where cosmetic appearance is secondary to strength and cost.

As-Fabricated

Passivation process

Mechanical brushing with abrasive belts creates a uniform directional linear grain pattern across sheet metal. Hides scratches and surface imperfections, produces a consistent semi-matte appearance. The most popular decorative finish for stainless steel and aluminum — used for kitchen equipment, architectural panels, appliance housings, and consumer product enclosures.

Brushed

Passivation process

Mechanical polishing with progressively finer compounds and buffing wheels produces a highly reflective, mirror-like surface. Removes all scratches, tool marks, and imperfections achieving the highest possible gloss. Used for stainless steel food service equipment, medical instruments, architectural trim, decorative panels, and premium consumer products requiring a flawless reflective finish.

mirror finish

Passivation process

High-pressure blasting with glass beads or aluminum oxide creates a uniform matte satin, non-reflective surface. Hides weld seams, scratches, and surface inconsistencies, produces a consistent fine grain texture. Used for aluminum and stainless steel brackets, enclosures, medical devices, and industrial components where a clean, uniform, non-glare matte appearance is desired.

Bead-Blasted

Passivation process

Electrostatic dry powder paint followed by thermal curing creates a durable, uniform matte or satin finish. Available in any RAL color, provides excellent corrosion and scratch resistance, thicker and more durable than wet paint. The most popular protective/decorative finish for steel and aluminum enclosures, electrical boxes, machine housings, and outdoor industrial equipment.

Powder-Coated

Passivation process

Electrochemical process creates a hard, corrosion-resistant, dyeable aluminum oxide layer on aluminum sheet metal. Available in any color (black, blue, red, clear), provides wear protection and improved corrosion resistance. Widely used for aluminum enclosures, electronic housings, aerospace components, and architectural panels requiring a durable, colored, corrosion-resistant finish.

Anodized

Passivation process

Hot-dip galvanizing immerses steel in molten zinc, creating a thick, corrosion-resistant zinc-iron alloy coating with a characteristic spangled crystalline pattern. Provides excellent long-term corrosion protection for outdoor and structural applications. Used for steel brackets, structural frames, outdoor equipment, fencing, and any steel component requiring durable rust protection in harsh environments.

Galvanized

Passivation process

Conventional spray painting with liquid paint (acrylic, epoxy, polyurethane) applied over a primed surface, available in any custom color and gloss level. Provides good corrosion protection and decorative color ideal for parts requiring custom color matching, intricate masking, or multi-color finishes where powder coating is not practical. Used for industrial equipment, automotive parts, and custom enclosures.

Painted

Passivation process

Chemical conversion coating creates a uniform matte black finish on steel sheet metal. Minimizes light reflection, provides mild corrosion protection, and does not affect dimensional accuracy. Used for steel tooling, fixtures, optical components, and hardware where a non-reflective black surface is desired often combined with oil or wax topcoat for enhanced corrosion protection.

Black-Oxide

Passivation process

Chemical treatment (citric or nitric acid) removes free iron and contaminants from stainless steel surfaces, restoring and enhancing the protective chromium oxide layer for improved corrosion resistance. Does not change appearance, dimensions, or surface texture. Standard post-fabrication treatment for all 304/316 stainless steel parts — especially medical instruments, food service equipment, pharmaceutical components, and outdoor stainless applications.

Passivated
Grinding & Lapping

Passivation process

Abrasive machining process using grinding wheels or lapping compounds to remove material and produce extremely flat, smooth surfaces with tight dimensional tolerances (Ra 0.1–0.8 µm). Surface grinding produces flat parts, cylindrical grinding produces round shafts, and lapping achieves ultra-flat mirror-like surfaces. Essential for precision gauges, bearing surfaces, die sets, and any component requiring extreme flatness and surface accuracy.

Grinding-&-Lapping

Passivation process

Mirror polishing is a finishing process that gives metal a smooth, shiny, mirror-like surface. It works by using abrasive compounds starting coarse and moving to progressively finer grades along with soft cloth or felt buffing wheels to remove scratches, tool marks, and other surface flaws. This process achieves the highest possible shine, with a surface roughness of about Ra 0.025–0.1 µm (extremely smooth). It’s commonly used for decorative stainless steel panels, medical instruments, automotive trim, jewelry, and premium consumer products that need a flawless, reflective finish.

Polishing-&-Buffing

Passivation process

High-pressure projection of glass beads, aluminum oxide, or other abrasive media onto a surface to create a uniform matte satin, non-reflective finish. Hides scratches, weld seams, and surface inconsistencies, produces a consistent fine grain texture (Ra 0.8–3.2 µm). Used for aluminum and stainless steel brackets, enclosures, medical devices, and industrial components where a clean, uniform, non-glare matte appearance is desired.

Bead-&-Abrasive Blasting

Passivation process

Mechanical brushing with abrasive belts or nylon brushes creates a uniform directional linear grain pattern across the surface. Hides scratches and surface imperfections, produces a consistent semi-matte appearance (Ra 0.4–1.6 µm). The most popular decorative finish for stainless steel and aluminum are used for kitchen equipment, architectural panels, appliance housings, and consumer product enclosures requiring a refined directional texture.

Brushing-&-Grain-Finishing

Passivation process

Post-machining process that removes burrs, sharp edges, and residual material from cut or machined surfaces, producing clean, smooth, safe-to-handle edges. Methods include hand deburring, tumbling, vibratory finishing, and thermal deburring. Standard for all handled parts, assemblies, and components where sharp edges would be a safety concern or interfere with assembly that’s essential for quality and safety in every manufacturing process.

Deburring-&-Edge Breaking

Passivation process

Electrochemical process that creates a hard, corrosion-resistant, dyeable aluminum oxide layer on aluminum surfaces. Available in any color (black, blue, red, clear), provides wear protection and improved corrosion resistance. Type II (standard) for general use, Type III (hard coat) for high-wear applications. Widely used for aluminum enclosures, electronic housings, aerospace components, and architectural panels requiring a durable, colored, corrosion-resistant finish.

Anodizing

Passivation process

Electrochemical process that removes a thin layer of metal from the surface by anodic dissolution in an electrolyte bath, producing an ultra-smooth, bright, highly reflective finish (Ra 0.05–0.4 µm). Removes micro-burrs, improves corrosion resistance, and creates a clean, sterile surface. Widely used for stainless steel medical instruments, food processing equipment, pharmaceutical components, and any application requiring ultra-clean, corrosion-resistant surfaces.

Electropolishing

Passivation process

Electrochemical deposition of a thin metal layer (chrome, nickel, gold, silver, zinc, tin) onto a substrate surface to improve appearance, corrosion resistance, wear resistance, or electrical conductivity. Chrome plating provides a bright, hard, reflective finish; nickel plating provides corrosion protection and a smooth base; gold plating provides excellent conductivity and tarnish resistance. Used for automotive trim, electrical contacts, fasteners, and decorative hardware.

Plating-(Chrome-Nickel-Gold)

Passivation process

Powder coating: electrostatic dry powder paint followed by thermal curing creates a durable, uniform matte or satin finish in any RAL color, with excellent corrosion and scratch resistance. Wet painting: conventional liquid paint (acrylic, epoxy, polyurethane) applied over a primed surface, available in any custom color and gloss level. Both provide protective and decorative finishes for enclosures, equipment housings, automotive parts, and outdoor industrial components.

Powder-Coating-&-Painting

Passivation process

Passivation: chemical treatment (citric or nitric acid) removes free iron and contaminants from stainless steel, restoring and enhancing the protective chromium oxide layer for improved corrosion resistance does not change appearance or dimensions. Conversion coating (chromate, phosphate, black oxide): chemical process creates a thin protective layer on metal surfaces, improving paint adhesion and corrosion resistance.
