Hanger tabs are designed for the support of ceilings and you should consult your engineer for individual allowable loads on single hanger tabs.
1.5 B Acoustical Roof Deck:
1.5 B Roof Deck is available as acoustical decking. Acoustical B Deck provides sound reduction where the under side of the deck is exposed to the interior. Our acoustical B deck is made by perforating the flutes of a standard 1.5 B deck profile.

|18ga.||2 or more||8'-10"||2.70 m|
Construction and maintenance loads:
SPANS are governed by a maximum stress of 26 ksi (180 MPa) and a maximum deflection of L/240 with a 200-pound (0.89 kN) concentrated load at midspan on a 1'-0" (300mm) wide section of deck. If the designer contemplates loads of greater magnitude, spans shall be decreased or the thickness of the steel deck increased as required. All loads shall be distributed by appropriate means to prevent damage to the completed assembly during construction.
