Worked example: estimate an order's mass
Assume ten rectangular, unperforated carbon-steel sheets, each 2 mm thick × 1000 mm wide × 2000 mm long. Use an approximate steel density of 7850 kg/m³. This is a planning estimate from nominal dimensions, not a measured delivery mass.
| Quantity | Input | SI value |
|---|---|---|
| Thickness t | 2 mm | 0.002 m |
| Width W | 1000 mm | 1 m |
| Length L | 2000 mm | 2 m |
Volume: V = L × W × t = 2 × 1 × 0.002 = 0.004 m³.
Mass per sheet: m = ρ × V = 7850 kg/m³ × 0.004 m³ = 31.4 kg.
Ten sheets: 10 × 31.4 kg = 314 kg. Cross-check: 15.7 kg/m² × 2 m² = 31.4 kg per sheet.
Turn the estimate into a usable quotation request
State the dimension order explicitly: “10 sheets; thickness 2 mm × width 1000 mm × length 2000 mm; estimated net steel mass 314 kg.” This line is incomplete until the grade, delivery condition, tolerances, finish and certificate requirements below are agreed. Ask whether pricing uses nominal mass, measured mass or a price per sheet.
Before ordering, check the usable area against the cutting layout. Sheet area alone cannot determine the number of parts: edge trim, cutting gaps, grain direction and machine limits can prevent a layout from fitting.
Write a complete order
- Product form, material grade and delivery condition or temper.
- Thickness × width × length, quantity and permitted substitutions.
- Applicable dimensional-tolerance standard, class and edition agreed with the supplier.
- Surface condition, protective film, flatness and grain direction where functional.
- Certificate and inspection requirements, cut-edge condition and revision.

Technical reference
SSAB: Metal-coated sheets — environmental product declaration (PDF) gives 7850 kg/m³ for steel density. Used here only as a reference density for the steel substrate; coating mass is not included. The calculation and ordering example are original educational examples. The stock table above retains legacy catalogue examples; confirm availability with the supplier.
