Trall in Swedish When my neighbor and the professionals who installed it call their expansive wrap-around backyard deck as 'trall' in the local language, my understanding is naturally that trall refers to much more than 'entryway/small deck.' This is confirmed by repeated visits (for other purposes) to the nearby hardware/lumber stores I visit. Trall does not refer to fiberboard since it is exclusively used for exterior (weather-resistant) purposes and is mostly impregnated wood (not good for interior use) or larch.
As for 'trallskruv,' you can do some looking based on this reference ( https://vsbyggskruv.se/en/our-brands/turbo-trallskruv/ ) -- 'decking screw.'

Trall in Swedish normally means an entryway/small deck or stairs leading up to the main door to a home.

Something other than duckboard/wood grating I know that it's normally wood decking/grating/duckboard...but it makes no sense in the context of the document, where the company manufactures fasteners and screws for wood, sheet metal, wood, concrete and "duckboard"?
Also Tråd- och trallskruv" makes me think of "fibreboard/duckboard screws"

Wondering if "trall" is some time of "fibreboard".
