Abstract: A fireplace surround structure is disclosed. The fireplace surround structure includes a mantel portion, a first vertical leg portion and a second vertical leg portion. The first leg portion and the second leg portion extend downward from the mantel portion at opposite ends to form a unitary fireplace surround structure. Each leg portion has a skeletal bar frame with a plurality of bar portions defining a three sided generally rectangular structure. Each of the sides has a lightweight non-combustible board portion attached on the exterior of the frame. The fireplace surround structure is open to one side and mountable on a wall surface. Each board portion is cast from a mix of Portland cement, silica, and cellulose fibers, which are combined and sintered into a flat board structure.

Abstract: A decorative mantel article for placement above and/or around a fireplace that is lightweight for facilitation of transport and placement is provided. Additionally, the decorative mantel exhibits a non-combustible quality heretofore undeveloped within the mantel industry, particularly for such articles that are provided with decorative aesthetic designs. Such a lightweight article is provided with all non-combustible components with dimensionally stable structural benefits for long-term mounting and usage, thereby providing a sufficiently strong mantel with a low overall weight measurement. A mounting component is further encompassed herein, as well.
