Chequered plates are same as plates, However small projection of same steel as per picture will be there.The small projection is kept for skid resistance and it will be used for walk way platforms.
Generally chequered plates are designated as Cheqd.PL -A o/p X Length X Width
Example: Cheqd PL-6 o/p X 1150 X 750
The term o/p means "over plate" or "over plain". It means thickness of the plate is excluding the chequer
The weight of chequred plate is higher than plane plate considering the projections (Chequers).
Total weight: length (m) x width (m) x thickness (mm) x 7.85 + extra weight = kg/plate
Generally the extra weight will be 6.1Kg approximately. However the following table shows the weight of chequerd plates
Please note that sectional properties of the chequered plate while designing for bending and deflection,are based on the plain thickness of the plate, excluding thickness of the chequer.
Have a nice day
