Steel plate: thickness, formats and weight
What a 1250×2500 and a 1500×6000 sheet weighs by thickness. Hot-rolled versus cold-rolled, galvanised and chequer plate.
Sheet weight is simple: area × thickness × steel density of 7.85 g/cm³. Below are ready figures for the two most common formats.
Sheet weight by thickness
| Thickness, mm | Weight per m², kg | Sheet 1250×2500, kg | Sheet 1500×6000, kg |
|---|---|---|---|
| 1.0 | 7.85 | 24.5 | 70.7 |
| 1.5 | 11.78 | 36.8 | 106.0 |
| 2.0 | 15.70 | 49.1 | 141.3 |
| 3.0 | 23.55 | 73.6 | 212.0 |
| 4.0 | 31.40 | 98.1 | 282.6 |
| 5.0 | 39.25 | 122.7 | 353.3 |
| 6.0 | 47.10 | 147.2 | 423.9 |
| 8.0 | 62.80 | 196.3 | 565.2 |
| 10.0 | 78.50 | 245.3 | 706.5 |
Hot-rolled or cold-rolled
Hot-rolled — rolled at high temperature. The surface is dark and scaled, tolerances are wider, and it costs less. This is the standard plate for steelwork, gussets and shims — anywhere the surface is not on show.
Cold-rolled — finished cold. The surface is smooth and bright, tolerances are tighter and thicknesses mostly stay under 3 mm. Chosen for painting, bending and visible parts.
Galvanised sheet is cold-rolled steel with a zinc coating: for roofing, gutters, ductwork — anything outdoors.
Chequer plate
Plate with raised lentil or diamond patterns. It goes where people walk: stairs, platforms, workshop floors, ramps. Chequer plate weighs about 5–8% more than plain plate of the same thickness because of the pattern itself.
We cut to your size at the yard. That beats hauling a whole 1500×6000 sheet when you only need two strips: a format like that already calls for a truck, and the offcuts still have to go somewhere.
You can work out weight and cost for your volume right here — or leave a request and a manager will quote it with a batch discount.
We stock these positions in Rolled metal.
