RAW METALLIC MATERIALS, a type of CIVIL AND STRUCTURAL MATERIALS.
Raw Metallic Materials are a type of Civil and Structural Materials. Materials used in warehousing and logistics services, such as shelves, racks and loading bays, belong in this subcategory because of their metallic composition. Rebarsalso known as reinforcement steelare steel bars or meshes of steel wires that serve as tension devices in reinforced concrete and reinforced masonry structures to strengthen and hold the concrete in tension. Cryogenic steels, including special alloys such as nine?percent nickel steel, are particularly suited for handling extremely low temperatures; for instance, cryogenic steel sheets are used to transport liquefied natural gas and liquefied petroleum gas.
