    I am glad to say that the phone is ringing, emails are coming in, all asking for pricing for various work.

     

    One of these is a decking project. The customer (a garden designer/landscape architect in London!!) has asked for a 35mm thickness 4m long hardwood decking with hidden fixings.

     

    My only problem so far is that my current suppliers, and others I ahve tried on the internet, can only supply 19mm or 21mm thickness.

     

    Couple of questions:

    1) Does anyone know of a supplier of hardwood decking in 35mm thickness?

    2) Why the difference in thickness.

    hello,

    1) yes, we are such a supplier (ipe decking only), I need to say that decking other then 19/20 or 21mm is always MUCH more expensive

    2) why the difference in thick? I have no idea since 20m is more then enough especially if it is hardwood decking, but some need special superdeck for some misterious reason.

    So if you are in need of a large quantity (10,000sqft / 1000m2) do not hesitate to contact us for a very competitive quotation! http://www.roquevalente.com

    Hi Roque

    I agree that the cost is crazy, however we only supply what Architects and Designers specify.

    The difference is usually for heavy traffic pedestrian use or commercial applications. The benefits being the thicker the timber decking the wider the Joist and deck span.

    Sometimes cost is not the most important factor, with a hardwood substructure and a thicker product the longevity is increase by a substantial amount; the labour ,however, doesn’t increase by much

    Correct, from the initial posting I did not know it was for heavy pedestrian use. We are mainly an exporting company but sometimes arquitects or contractors contact us directly with almost impossible orders. We just sell a few widths (90/95/120/140 and 145mm wide x 19/20/21mm thich and random lengths) while these arquitects or contractors require specific quantity of boards of a certain width and even specified lengths!

    Orders like this will reduce output (#boards produced per log) will reduce significantly and sometimes this doubles the price. It is true howver that the quantity of substructure will be reduced, however, substructure is a fraction of the total price so this is not quite the argument that would justify the request for 35mm thick. Also labour is more affected by the lengths of the boards (more boards to install per m2) then by the thick of the boards. Anyhow, heavy pedestrian use would justify, or just a client with a big wallet who doesn’t care.

    So if you need good quality for ordinary use, just order random lengths, standard thick and in respect of wrapping and cupping do consider narrower widths! cheaper and safer.

    I do agree with your comments especially the narrow boards are more adapt in reducing cupping issues. We need designers and architects to appreciate this and stop specifying wide boards like 200mm at 21mm thickness, whilst the installation might look good for about two minutes just before it rains and the boards jump up and run away all by them selves…

     

    It is usual for someone that specifies the thicker timbers either 28mm or 35mm to specify a hardwood substructure.

    Hi Stuart, I manufacture timber decking materials.   35mm is possible of course, but not the best choice for most species because most sawmills still work to imperial measures even though they mostly can talk these days in metric.  For example, the sawn size closest to 35mm is 38mm, this is the old 1.5″ size.    If you start with 38mm sawn, you cannot get 35mm clean from the timber after drying.  You would have to start with 50mm timber and that would be a huge waste of wood and an expensive way to do this.  From 50mm (depending on the species you might get 43-45mm.   From 38mm, you would get about 30-33mm.
