Framing details for openings in steel deck assemblies utilizing channel headers and angle supports configured for varying opening dimensions. For openings ranging from 6 inches to 24 inches, the assembly uses L2x2x1/4 angles positioned below the deck with 5/8-inch diameter fasteners. For openings between 24 inches and 72 inches, C3x4.1 channels frame the opening with steel deck flutes adjusted to achieve bearing on the channels up to a maximum dimension of 6'-0". For larger openings spanning 72 inches to 98 inches, heavier C4x5.4 channels frame the opening with maximum dimensions of 8'-2" while maintaining deck bearing requirements. Steel deck per plan surrounds all opening configurations.
