    I need to attach some big brackets to a block wall to hold a lean to roof. I was going to use steel expansion rawl bolts but then I found some heavy nylon fixings with coach screws.

    Which is stronger ? I am aware that over tightening steel bolts can crack the block. And as the bracket holes are quite close together, I would guess that the risk of cracking is higher.

    metal al the way

    a sales rep told me they are trying to stop the plastic ones due to fire regs
    the plastic ones melt and stuff fall off walls blocking fire escape routes and endangering firemen

    That's a really obvious & logical thought.
