I do 400mm centers with wooden decking. Not sure composite would be any different.

Alan · Answer

No different to normal decking use 400mm spacing for the joists and you will be good to go

Steven · Answer

350mm is the normal recomendation from most manufacturers.

Gary · Answer

I would do the spaces at 350mm as the composite decking is little bit hard walking than wooden

I would recommend 3/4m spacer for each gap keeping it consistent
