Difference Between Plate And Sheet

Stainless sheet and plate look similar in shape, strictly speaking, they are different in thickness and durability, sheets are thinner, usually 6mm or less, and used for lightweight residential applications, plates provide more tensile strength and are used in heavy-duty applications.

Stainless Steel Plate & Sheet Sizes

Standard width: 1000 mm, 1219 mm, 1500 mm, 2000 mm, non-standard width is slitted and cut in narrow width, width from 6 mm to 3048 mm.

Thickness range from 0.3 mm to 150 mm, there are varieties of thickness, thin thick sheet (0.2 mm – 4 mm), thick thickness plate(4 mm – 20 mm), medium thickness plate (20 mm – 60 mm) and heavy thickness plate (60 mm – 115 mm).

Stainless steel plate & sheet gauge range from 1 to 30, size range thickness from 0.32 to 7.15 in mm, the higher the gauge, the thinner the material.

Plate & Sheet Surface Finishes

Stainless steel plate & sheet have various finishes condition to suit application, there are main surface finishes below, these finishes can be obtained by cold rolling or hot rolling producing method.

  • NO.1 – Hot rolled, annealed, and descaled
  • 2D – Cold rolled, dull finish
  • 2B – The general-purpose, cold rolled, smooth finish
  • BA – Bright, cold rolled, highly reflective finish
  • NO.3 – Intermediate polished finish
  • NO.4 (BRUSHED)– General-purpose ground polished finish produced from 2B finish
  • NO.8 (MIRRORED) – Highly reflective ‘mirror’ finish produced from 2B finish

Cold Rolled & Hot Rolled Differences

There are some differences between hot rolled steel and cold rolled in metal industry, the main difference is manufacturing process of steel, Hot rolled steel is rolled at high temperature, this makes steel easy to form and fabricating, hot rolled type steel is easier to get target sizes and dimensions after processing, Cold rolled steel is rolled on the basis of hot rolled steel, then picking and remove scale on the surface, cooling at room temperature, they have benefits respectively。

Hot Rolled Characteristics

  • Uniform grain size, avoiding structure defect
  • Improve properties
  • Shaped and formed easily
  • Non metallic inclusions inside steel remain
  • Stress exists
  • Not easy to control width and thickness precisely
  • Scaled surface
  • Cheaper than cold rolled steel

Cold Rolled Characteristics

  • Clear and smooth surface
  • More finishes option
  • Closer tolerances
  • Stronger hardness
  • Limited in a few shapes
