 L.B. Foster’s Open Grid was developed to meet increasing performance and reliability needs, as highway traffic volumes and truck loadings continue to grow, without adding additional deck dead load. Open grid design durability is linked directly to transverse stiffness — the ability to transmit load from one main beam to adjacent ones.
