Looking to build a deck with tigerwood. I will likely use screws and plugs. I am looking for thoughts on 4/4 vs 21mm?
Thank you,
Allen

do you mean 5/4?
cause there is less than half a mm difference between 4/4 and 21mm boards.
my understanding is that it is 2m which seems awfully small

clarify
4/4 boards are 13/16", which is something like 20.6 mm.
not sure what you mean by "something like 2m"
whats two meters?
you mean 2mm?
what do you think is 2 mm? the 4/4 boards? cause the 21mm board is going to be....21mm just under 7/8. and the 4/4 is 13/16"
Nothing conventional about 13/16" thick 4/4 stock
4/4 is a rough lumber dimesion. There is no "standard" or specific thickness. Certainly not 13/16". Dressed sizing is usually supplied at exactly 3/4", but it can vary (usually up to 1/8" strong or weak) depending on what you request from your supplier or what they get dressed from their wholesaler. Now, when you order "1X", that nomenclature refers to dressed sizing and the lumber thickness should always be 3/4" thick. This rough lumber nomenclature applies to 5/4 lumber as well. That's why Windsor One* provides a 5/4 dressed size that measures exactly 1" thick and Primelock* provides the same 5/4 measuring 1-1/6". I've also seen other manufacturers provide 5/4 at 1-1/8" and 1-3/16" dressed thickenesses.
*Brands
Sometimes the 21mm is actually a little cheaper than 4/4. I expect it's because tropical hardwoods are milled in countries that use the metric system and it's cheaper for them to mill only one size. I'd frame at 12" oc if I was using 4/4 though. Also check out the Camo screw system instead of plugs and screws. Many, many times faster and looks better I think.
