Can a glulam beam warp?

[Kallebo]

I have a glulam beam that has been standing under a tarp in the garden for a year. Now that I take it out, I find that it is not completely straight. I measured against the floor that it has bent about 3 mm, which is fully visible (L/1400).

Can I use it as a ridge beam in a garage or should I buy a new one :/

I would think it's within tolerance for a new empty one.
In any case, you can use it without any problem. Turn the bend upwards.
