4.2m span. Is glue-laminated timber needed?

[bjornligan]

Hi. Going to build a garage with a carport in front. Outer dimensions of the garage will be 4200.

Planning to have tiles and snow load zone 2.5
Mono-pitch roof with 15-degree slope.

With cc600, can I manage with 225mm?

I'd prefer to avoid extra costs for glulam if it isn't necessary, but I don't want to under-dimension. The calculations I find (moeleven) only include glulam, not construction timber.

Best regards, Kristian

What are you talking about???

Oh, that might have been a bit unclear. I wasn't thinking of having trusses, but rather laying beams between two walls of different heights.
