| 3mm | 24.73 | 222.55 | 296.73 |
| 4mm | 32.97 | 296.73 | 395.64 |

The factor 1.05 accounts for the 5% extra weight of the raised diamond/chequered pattern on the plate surface.
Step 1: 8 × 7.85 × 1.05 = 65.94 kg/m²
Step 2: Area = 1.5 × 6.0 = 9.0 m²
Step 3: 65.94 × 9.0 = 593.46 kg
Chequered plate weight per m² = Thickness × 7.85 × 1.05. The 1.05 factor adds 5% for the raised diamond pattern. Example: 6mm chequered plate weighs 6 × 7.85 × 1.05 = 49.46 kg/m².
The diamond/chequered pattern adds approximately 5% extra weight over a plain plate of the same thickness. This is accounted for by the 1.05 multiplier in the formula.
A 6mm chequered plate weighs 49.46 kg/m². A standard 1500×6000mm sheet weighs 445.10 kg, and a 2000×6000mm sheet weighs 593.46 kg.
Common thicknesses are 3mm, 4mm, 5mm, 6mm, 8mm, 10mm, 12mm. For industrial flooring, 6mm and 8mm are most common. Thicker plates (14-25mm) are used for heavy-duty applications.
Chequered plate weighs 5% more than plain plate of the same base thickness due to the raised pattern. A 6mm plain plate weighs 47.10 kg/m² while chequered weighs 49.46 kg/m².
