    Well received some information regarding marine plywood (i order and S&G boat)

    But there seems to be a lot of terms i dont understand, below are the points i couldnt understand:

    1 x 40HQ / 55 Cubic Meter.

    BS 1088 MARINE PLYWOOD
    ========================
    4ft x 8ft

    4mm........(3/16") (unit price) USD.....($Price dunno total or minimum order? CBM)
    GLue: WBP,Melamine,MR,E0,E1,E2
    Size: 1220 x 2440mm
    Grade: BB/BB,BB/CC

    I am also not sure if that is good plywood or not, i asked for a sample but the minimum sample they can send is 55 cubic meters ....
    So any ideas from our plywood experts ?

    BS (British Standard) 1088 is a marine grade plywood. BB/BB is both faces with minimal blemishes (paint standard). BB/CC has one face with patches. I don't thing that BB/CC complies with 1088.

    BS 1088 MARINE PLYWOOD
    BS 1088 = British Standard 1088 (a standard to which the plywood conforms)

    4ft x 8ft
    Sheet size (Widh x Length) in feet

    4mm........(3/16")
    Thickness

    Glue: WBP
    WBP = Weather and Boil Proof

    Melamine, MR
    Melamine-formaldehyde glue with Resorcinol

    E0,E1,E2 = Formaldehyde emmission class (EN 120), E0 or E1 means no emmission or low emmission and are to be preferred, since formaldehyde is cancerogene.

    Size: 1220 x 2440mm
    Sheet size (Widh x Length) in millimeters

    Grade: BB/BB,BB/CC
    Veneer quality, face/back surface. A is the highest, B is second choice. D is the lowest grade, but I wouldn't go below B..

    Regardless of what the label says, a personal inspection of the plywood is the true test. Edge voids and internal defects can be seen, as of course can the surfaces, which should be free of repairs and look pretty much near perfect. Internal defects, voids and repairs suggest the sheet is mis-marked (a common problem with some suppliers today) and should be rejected out of hand.

    Thx for the feedback !
    Thats a problem because i am still searching and so far only 1 supplier was found (the stupidly expensive one) my next step is a trip to alex since there seems to be more suppliers there.
    Ill stick to your advice PAR do the inspection and take photos, i guess its too risky to import from an unknown source.
    If i cant find anything ill have to buy from the expensive supplier (providing i do an inspection as well)

    Gonzo / daiquiri thx a lot for the explanation :D

    Try to contact Apex1 too, he might be able to give you few hints on suppliers to call.
