Chequered plates are steel flooring used in industrial structures. Normally the maximum spacing of chequered plates are between 1 metre to 1.2 metre.
Chequered plate thickness is measured excluding the chequeres. That is to say 6mm thick chequred plate means 6 thick plate with chequres above it. Hence the weight of chequred plate comes higher as compared to plain plates. Weight of chequeres are approximately 6.1 kg/m² over and above the plate weight.
Dead weight of chequered plates are as below.
- 5mm thick chequred plate weight = 45.35 kg/m²
- 6mm thick chequred plate weight = 53.2 kg/m²
- 7mm thick chequred plate weight = 61.05 kg/m²
- 8mm thick chequred plate weight = 68.9 kg/m²
- 10mm thick chequred plate weight = 84.6 kg/m²
- 12mm thick chequred plate weight = 100.3 kg/m²
Weight of chequered plate (kg/m²)= thickness (m) x 7.85 (kg/m³) + 6.1
If you want to find weight of total plate to be used in project, then
Total weight of chequered plate (kg) = Length (m) x Width (m) x (Thickness (m) x 7.85 (kg/m³) + 6.1(kg/m²))
Comments
the formula I get is
5mm =. (0.005*7850)+(5*0.16)
6mm = (0.006*7850)+ (6*0.16)
and so on...
