Area Calculation
In case drawings are not available and processing is made according to dimension offered by users, the area means that the quantity of steel grating actually delivered is multiplied by the sum of length and width, containing tapping and notching part.
We can offer drawings and design the layout plan of steel grating for users. Area is calculated based on total external dimension in drawings, containing tapping and notching part.
For special shaped steel gratings, area is calculated based on length (L) ×width (W) for the total number of blocks, with notching part included. Refer to diagram for several typical samples.
