Mirror Finish / Polished Stainless Steel Plates – Supply & Custom Cut Service

Table of Contents

What is Mirror Finish or Polished Stainless Plate?

Mirror finish stainless steel plates refer to highly polished, reflective steel sheets that undergo mechanical or electrochemical polishing to achieve a glossy, almost glass-like surface. Grades like SS 304, SS 316L, and SS 430 are commonly used for achieving this mirror polish due to their excellent corrosion resistance and formability. These plates are often finished to No. 8, BA (Bright Annealed), or custom levels of surface finish (e.g., RA < 0.2 µm), depending on the application.

At Hindustan Steel Corporation, we offer ready stock and custom-polished stainless steel plates in multiple mirror finishes – including No. 8 Mirror, Super Mirror, BA, and Satin finishes – suitable for architectural, food, pharmaceutical, and decorative applications.

Applications Across Industries

Mirror finish and polished stainless steel plates are extensively used where both aesthetic appeal and hygienic properties are critical. Key application sectors include:

  • Architecture & Interior Design: Elevators, wall panels, cladding, handrails, sculptures
  • Food & Beverage: Kitchen counters, utensils, processing equipment
  • Pharmaceuticals & Biotech: Cleanroom partitions, lab-grade surfaces
  • Retail & Hospitality: Display counters, signage, furniture, ceilings
  • Automotive: Trims, exhaust systems, interior applications
  • Marine: Corrosion-resistant decorative panels in luxury yachts and ships

Surface Finish, Mechanical Strength & Reflective Quality

While mirror polished stainless steel plates are primarily used for their visual appeal and cleanability, they also retain the base mechanical properties of the underlying stainless grade – whether it’s austenitic (SS 304/316), ferritic (SS 430), or duplex.

Grade Mirror Finish Surface Roughness Tensile Strength Typical Use
SS 304 No. 8 / BA < 0.2 µm ~515 MPa Architecture, Food, Pharma
SS 316L No. 8 < 0.1 µm ~485 MPa Marine, Biotech
SS 430 BA ~0.3 µm ~450 MPa Interiors, Elevators

Reflectivity is close to 90% in high-grade No. 8 finishes, making it ideal for high-end visual applications. At Hindustan Steel, we ensure consistency in gloss level, uniformity, and scratch resistance through precision polishing.

Surface Finish Standards & Equivalent Grades

Mirror-polished stainless steel plates are manufactured in accordance with global finishing standards:

  • ASTM A240 / A480 – Surface finishes like No. 8, BA (Bright Annealed), and 2B base
  • EN 10088-2 – Finish designations like 2P (polished) and 2R (BA)
  • JIS G4305 / G4304 – Japanese finish equivalents
  • ISO 4287 / 1302 – Roughness measurement standards (Ra values)

Common Equivalent Grades:

  • SS 304 ⇔ 1.4301 ⇔ X5CrNi18-10
  • SS 316L ⇔ 1.4404 ⇔ X2CrNiMo17-12-2
  • SS 430 ⇔ 1.4016 ⇔ X6Cr17

We also polish plates in customized grades such as SS 202, SS 310, Duplex S31803, and others based on order volume and application.

Plate Thickness, Sizes & Finish Options

We supply mirror-polished plates in both standard and custom-cut sizes. Available configurations include:

  1. Thickness Range: 0.4 mm to 100 mm
  2. Width: 1000 mm / 1250 mm / 1500 mm / 2000 mm
  3. Length: 2500 mm / 3000 mm / Coil / Cut-to-Length (CTL)

Finish Options:

    • No. 8 Super Mirror Finish
    • Bright Annealed (BA)
    • 2P / 2R (Ra < 0.2 µm)

Custom Satin / Brushed / Dual Finish

Optional PVC coating can be provided for surface protection during transport or fabrication.

Polish Grades, Toughness & Quality Control

Each polished stainless plate undergoes a controlled multi-stage polishing process, including:

  • Mechanical grinding → Buffing → Electro-polishing (if required)
  • Final finish with calibrated abrasive grits and surface passivation
  • RA Testing and Glossmeter verification for mirror quality assurance

Our polished plates retain full mechanical strength of base grade, including:

  • High tensile & yield strength
  • Impact resistance in low-temperature environments
  • Crevice and pitting corrosion resistance (in SS 316L)

Hindustan Steel ensures dimensional stability, scratch resistance, and uniform gloss level across every batch.

Fabrication Advice for Mirror Finish Plates

Due to the delicate surface, the following handling precautions are advised:

  • Use soft, non-metallic tools during fabrication
  • Edge deburring before installation to avoid chipping
  • Welding should be limited and followed by re-polishing if required
  • Protective film must remain intact till final assembly

We offer pre-polished edges, laser cutting, waterjet shaping, and CNC bending for customized architectural or industrial use.

Buyer Guide – How to Select the Right Mirror Plate

When choosing mirror finish plates, ask:

  • What grade? (304 for decor, 316L for chemical/pharma, 430 for economy use)
  •  What finish? (No. 8 vs BA vs PVD-coated vs Satin)
  •  Which thickness? (Elevators = 1–1.5 mm; Tanks = 2–4 mm)
  •  What size? (Standard sheets vs Cut-to-size vs Coil)
  •  Do you need dual side polishing or only one side?
  •  Will welding or bending be done later?
