Centres is 300mm then it can only be used at 300mm centres.Ĭost Index is a rough estimate of the order of Joists and Centres, from cheapest to most expensive, based on RRP. This application will specify a list of acceptable JJI-Joists once you enter your support conditions, load case and clear span. Use ForteWEB to determine solutions for conditions beyond the scope of.
