    I have been persuaded to renovate a garden bench. Cast iron end with wooden slat type.
    There's no real money in the pot for buying decent hardwood, so could I use ply?
    wickes and B&Q do a Temperate Softwood Ply (Structural) for reasonable money.
    There are 5 weight bearing slats 60 x 18 x 1200 . They are supported 50mm in from each end with just a tie strip midway. Would this support two adults
    If so, and if I were to prime , undercoat and finish it would it last two or three years?

    I think even the best quality WBP ply would tend to delaminate over the years.....if hardwood is a no go, then tanalised timber laths could be an option.
    I'd go thicker than 18mm, personally.

    Hardwood unless it is to be stored undercover when not in use. Last time I looked they were £12.99 in wilkinsons.

    Ply, any ply, would be no good in terms of weather resistance. And I would suspect no good anyway when cut to use as slats.

    I wonder if the cheapest option would be to select some knot-free 22mm floorboards, rip them down to size and treat? Our gate is still going strong after 12 years:cool:

    25mm CCA is best. Done it loads of times,

    Thank you. Lots of good helpful suggestions here. Think I'll ask around for hardwood decking off cuts that I can have ripped to size.

    Anyone got any apare? Chippenham area, Wilts. SN13.

    I used decking to do mine this year, just run it down the saw.
    I also replaced the timbers on the garden table the same way

    I would think even cheap whitewood spruce/pine would last longer outside than ply (and be cheaper too)

    Larch would work really well and only cost a few quid, if there's a good local sawmill
