Glulam beam weight

[gemshan1]

Hi all, hope to be doing a loft conversion soon and just wondering how heavy a 90mm x 300mm x 3.4m glulam beam would be, would it be a two man job or? or too heavy?

Roughly 0.01m3, so 40+kg each on a quick in my head calculation? At that length definitely 2+ person job given where you're getting them to.

I would guess slightly heavier at 50kg

its probably a 90 x 315 section and spruce timber density around 550kg per metre

1 person would struggle

That’s great so definitely no crane needed.

Just out of interest are glulam beams cheaper to use than steel?

Out of interest, can a timber beam take the loads instead of steel

Depends what you need them for, that would be a question for your structural designer really.

If you're going for reasonable dimensions and ability to build with fewer people, look into composite beams eg flitch beam which is two timbers with a steel plate bolted in the middle.

Actually a total of about 6 beams to support a loft room floor.
