Hello,
Factory Mutual FM uses different assembly numbers for the roof with Bar joists as supports.
Does anybody know why bar joist assemblies are classified as separated from other Steel members?
Finally, they are concerned with the clip pulling out from the structural element - thickness is the only controlling factor.
