USG Corp. has unveiled its USG Securock Brand Concrete Roof Deck Panel, a durable structural panel that can be combined with other noncombustible materials to create a one- and two-hour fire-rated roof/ceiling assembly. Designed with great uplift ratings and to carry gravity and lateral loads, USG Securock Concrete Roof Deck Panels are mechanically fastened to cold-formed steel joists or framing members, and roof membranes or insulation attach directly over the panels. The panel meets the criteria of ASTM E136-04 for use in all types of noncombustible construction.
