A: In general there is greater flexibility in the design of the box gutter. The size of the gutter is still determined by the size of the roof and the design rainfall intensity, but the location of the sump can be chosen. The traditional sump can be eliminated or reduced to 50mm depth depending on the total gutter depth. Part of our professional support package service can include the sizing of the box gutters.
