Allowable loads for top-mount joist hangers Installed on steel beams with wood nailers

MiTek-USP Top Mount Hangers have been tested installed to various nailers. Wood nailers may be installed to the top of steel beams, concrete and masonry walls.

For allowable loads, it’s important to use a correct hanger attachment with a nailer and to ensure that the nailer is sized correctly. 

THE WRONG WAY to install top-mount joist hangers on a steel beam: Improperly sided top flange backing.


For more information on the allowable loads for common top mount hangers installed on 2x, 2-ply 2x, 3x and 4x nailers, please review this technical bulletin.
