Does this truss need support from a load-bearing wall, or is it self-supporting?
I can add that the manufacturer does not respond to emails...

A bit odd in appearance, but the idea is probably that it should be self-supporting over about 7 meters. What is the snow zone?
Is it divided like the image, yes unfortunately it needs to be, above or below.

Point 7 refers to a setup/support, almost missed it when I was building my garage.
Is it possible to buy stock (preferably) self-supporting trusses for a 6m wide house?sir_daniel said:
It is a bit tricky to enter the calculation of a truss without knowing the parameters. They have obviously used a known calculation program. If you compare with Träguiden's data on a W-truss with a roof slope of 1:2 (27 degrees), the upper and lower frames have the same dimensions, but reversed. The struts, on the other hand, are slimmer than Träguiden's, 70 mm instead of 145. It's still in the same ballpark.
6 m self-supporting is no problem. In Skåne, you can at least reach 11 m.
7 should be a reinforcement. It is probably the outlines in 1 and 5 that are the support points.
With a W-truss, 11 m is probably a realistic limit for Skåne. With other constructions, there are almost no limits other than economic ones.
It might not be what I call a W-truss, but sure, there's almost no limit to the span of a truss.
