Galvanized Steel Sheet Weight Chart and Calculator for Easy Estimation

Galvanized Steel Sheet Weight Chart and Calculator for Easy Estimation
Accurately estimating the weight of galvanized steel sheets is essential for budgeting, procurement, and logistics. Ruixiang Steel Group provides a comprehensive weight chart and calculation guide to simplify your planning process.

Weight Reference Chart
The table below lists the theoretical weight per square meter of galvanized steel sheets based on a steel density of 7.85 g/cm³:

Thickness (mm) Weight (kg/m²)
0.5                     3.93
0.8                     6.28
1.0                     7.85
1.2                     9.42
1.5                    11.78
2.0                    15.70
2.5                    19.63
3.0                     23.55
*Note: The values above represent the base steel weight. The galvanized coating typically adds 2.5–3.0 kg/m² to the total weight, depending on zinc coating thickness (e.g., Z30–Z275).*

Simplified Calculation Formula
Use this formula to estimate the weight of galvanized steel sheets:
Weight (kg) = Length (m) × Width (m) × Thickness (mm) × 7.85

For a more precise estimate including the zinc coating:
Total Weight ≈ Base Weight × (1.01–1.04)

Example Calculation:
A 1.2 mm thick, 1 m × 1 m galvanized sheet weighs:
1 × 1 × 1.2 × 7.85 × 1.02 ≈ 9.61 kg

Factors Influencing Weight
Dimensional Tolerances: Minor variations in thickness and width during manufacturing.

Zinc Coating Thickness: Heavier coatings (e.g., Z275) increase weight.

Material Composition: Slight differences in steel density.

In most cases, the difference between theoretical and actual weight is within ±0.5%. Theoretical weight is commonly used for trade and project calculations.
