Suspended load attachments from metal roof decks require specific plate washers, angles, and hanger assemblies depending on weight capacity limits. A supplier-provided hanger is secured through the metal roof deck using a one-quarter-inch by four-inch plate or an angle section with two number eight self-drilling screws. The assembly supports maximum point loads per flute ranging from fifteen pounds up to sixty pounds depending on the specific configuration. Suspended loads from the roof deck are restricted on deck spans greater than seven feet and single spans greater than six feet with a minimum twenty gauge deck requirement.
