Steel Plates Weight

Reference data and engineering information about steel plates weight for material properties applications.

Overview

Engineering reference data for Steel Plates Weight in material science and properties.

$\sigma = \frac{F}{A}$

Force per unit area.

$\varepsilon = \frac{\Delta L}{L_0}$

Change in length per original length.

$\sigma = E \varepsilon$

Stress proportional to strain in elastic region.

$\Delta L = \alpha L_0 \Delta T$

Length change due to temperature.

Symbol	Description	Unit
$\sigma$	Stress	Pa
$\varepsilon$	Strain	—
$E$	Young's modulus	Pa
$\alpha$	Thermal expansion coefficient	1/°C
$\Delta T$	Temperature change	°C

Steel plate weight per square foot for standard thicknesses (hot rolled mild steel, density ~490 lb/ft³):

Steel plate weight per square meter for standard thicknesses:

Conversion	Value
1 in	25.4 mm
1 lb/ft²	4.88 kg/m²

For hot rolled mild steel plates (density ≈ 490 lb/ft³ or 7850 kg/m³):

Imperial (weight per ft²):

$W = 40.8 \cdot t$

where $W$ is weight in lb/ft² and $t$ is thickness in inches.

Metric (weight per m²):

$W = 7.85 \cdot t$

where $W$ is weight in kg/m² and $t$ is thickness in mm.

Steel plates are typically stocked in the following standard dimensions:

System	Widths	Lengths
Imperial	36″, 48″, 60″	96″, 120″, 144″
Metric	—	2000 × 3000 mm
