    Which is cheaper in ££ and in green terms please - I need to factor in plasterboard fire protection for steel and intumescent varnish for gluelam. I'm supposed to have the answer for our engineer tomorrow - and I have a day job to do.

    steel is cheaper

    wood is nicer and greener so long as it does not come from too far away.

    Glulam typical 360 x 140mm cost £35 per m steel say 203 x 133 x 25kg ub £20 per m

    with glulam you will require a deeper section for the same structural qualaties, head heights can be an issue

    Glulam far more attractive and easier to work with when fixing as part of a timber roof, we often use steels to support joists (head height reasons) but if you include the cost of the timber to fill the web very little difference in cost. see photograph

    also Glulam far more attractive

    Steel doesn't grow on trees.
    In terms of travel, neither are produced in any great quantities in the UK, Glulam is likely to be European timber. Steel is likely to Chinese.
