Question

Can you please give me a website that tells me the uses and pictures of a "Floor beam" and a "Jois".

"Floor beam" and "Joist" are the same thing. They are the pieces that support the flooring.

Answer 3

A beam is a timber or combination of 2x12s nailed together to span an area where joists are to be joined. The joists are the individual 2x8's and larger depending on the span without support. These would be considered stick built.

There are manufactures beams, and joists.

Which are you looking for?

Beams are considered to be load bearing therefore are much larger and stronger than a single joist. A beam can support as much as 1/2 the entire weight of the floor.
