Steel Plate Thickness Discrepancy and Classification

The categorization of steel plate thickness into four distinct types, namely thin plate, medium plate, thick plate, and extra thick plate, piques curiosity. But how is this classification determined? Delving deeper into the realm of steel plate thickness, we discover that the classification is a broad concept. Now, let’s journey together through the nuances of steel plate thickness discrepancies and classifications.

Specifications of Steel Plate Thickness

The specifications of steel plate thickness are as follows, in millimeters:

  • Thin plate: 0.2mm, 0.25mm, 0.3mm, 0.35mm, 0.4mm, 0.45mm, 0.5mm, 0.55mm, 0.6mm, 0.7mm, 0.75mm, 0.8mm, 0.9mm, 1.0mm, 1.1mm, 1.2mm, 1.25mm, 1.4mm, 1.5mm, 1.6mm, 1.8mm, 2.0mm, 2.2mm, 2.5mm, 2.8mm, 3.0mm
  • Medium plate: 3.2mm, 3.5mm, 3.8mm, 4.0mm, 4.5mm, 5.0mm, 5.5mm, 6.0mm, 7.0mm, 8.0mm, 9.0mm, 10mm, 11mm, 12mm, 13mm, 14mm, 15mm, 16mm, 17mm, 18mm, 19mm, 20mm
  • Thick plate: 21mm to 60mm
  • Extra thick plate: 60mm and above

Classification of Steel Plate Thickness

Let’s categorize these dimensions for a clearer understanding:

  1. Thin plate: Encompasses steel plates with a thickness ranging from 0.2mm to less than 3mm.
  2. Medium plate: Envelops steel plates with a thickness spanning from 3mm to 25mm.
  3. Thick plate: Envelops steel plates with a thickness ranging from 25mm to 60mm.
  4. Extra thick plate: Features steel plates with a thickness of 60mm and above.

What are the Units for Steel Plate Thickness?

In the intricate process of procuring steel plates, understanding the units becomes pivotal. In China, two standard units prevail:

  1. The widely embraced international unit, “millimeter (mm),” and the traditional Chinese unit, “li.” For instance, when one requests a steel plate of “5 li thickness,” it translates to a 5mm thick steel plate.
  2. Another international unit, “centimeter (cm),” coexists with its traditional Chinese counterpart, “centimeter.” Therefore, inquiring about a “1-centimeter thick steel plate” implies a steel plate measuring 1 millimeter or 10 millimeters in thickness.

Steel Plate Thickness Discrepancy: Unraveling the Mystery

Unraveling the mystery behind steel plate thickness discrepancy, we delve into the realm where actual thickness diverges from theoretical dimensions, often by a fractional margin of 0.25mm or 0.5mm. Imagine a 10mm thick steel plate having an actual thickness of 9.75mm or 9.5mm, a norm in the realm of steel production.

Why Does Steel Plate Have Discrepancies?

Venturing into the market dynamics, steel plates, akin to commodities, tailor their thickness based on market preferences. Comparing steel plates to apples, where thickness determines sweetness, market trends dictate the choice of thickness. Steel plate manufacturers, like farmers planting crops, respond to market demands, ceasing production of less popular thickness variants, leaving only those with noticeable discrepancies.

What are the Values of Steel Plate Discrepancies?

The values of discrepancies often oscillate between 0.25mm and 0.5mm, rendering a 10mm theoretical thickness to an actual thickness of 9.75mm or 9.5mm. A nuanced approach arises when purchasing steel plates with thicknesses below 2mm. Merchants explicitly communicate specific thickness values, exemplified by 2.75mm being considered 3mm thick and 3.5mm deemed 4mm thick.
