Frequently Asked Questions
How is beam shuttering calculated?
For a beam, we calculate area for the bottom face and two side faces. Top face is left open for concreting. Formula: (Width + 2*Depth) * Length.
What sizes of plywood does it assume?
The calculator estimates sheets based on the standard 8 feet x 4 feet (32 sq.ft) plywood size commonly used in construction.
