Type O2 loading chart & m2 weights

Figures detailed are calculated in accordance with BS4592-0: 2006 +A1: 2012. Loadings reduced to maintain deflections within 1/200th of the clear span or 10mm whichever the lesser. In addition to the distributed load the gratings also fullfill a concentrated load on the edge with a 1.5kN / 200x200mm contact area based on max 4mm deflection OR L/200 as listed
