Hollowcore Load Span Table

The spans indicated below have not been limited to 50 x unit depth usually used to minimise the dynamic movement in the planks. We therefore do not recommend spans greater than the following: 150mm planks — 7.50m, 200mm planks — 10.00m &  250mm planks — 12.50m. Spans that exceed this are shown in grey.
