This one used to confuse me all the time, I would get them mixed up and around the wrong way, which would lead to much confusion between Adam and I. What is the difference between bearers and joists? What do they do?
What Are Bearers and Joists?
Bearers are the timber or steel that attaches directly to the stumps in the ground, that supports the deck of flooring structure. Joists are the timbers that then attach across the top of the bearers, after which the timber or particle board floor is then attached.
This structure forms the base for the deck, or timber floor, or the second level floor. Whilst it appears to be such a simple structure, it forms the basis of the whole, home or deck. The size of bearer, usually needs to be engineered to ensure correct load distribution, to prevent a collapse of the structure.
Did you know the difference between bearer and joist, or was it just as confusing for you?
