2. Cold-formed steel - Wikipedia

   en.wikipedia.org/wiki/Cold-formed_steel

   Cold-formed steel, especially in the form of thin gauge sheets, is commonly used in the construction industry for structural or non-structural items such as columns, beams, joists, studs, floor decking, built-up sections and other components. Such uses have become more and more popular in the US since their standardization in 1946.

3. Composite construction - Wikipedia

   en.wikipedia.org/wiki/Composite_construction

   A composite steel deck combines the tensile strength of steel with the compressive strength of concrete to improve design efficiency and reduce the material necessary to cover a given area. Additionally, composite steel decks supported by composite steel joists can span greater distances between supporting elements and have reduced live load ...

4. Deck (building) - Wikipedia

   en.wikipedia.org/wiki/Deck_(building)

   A deck is also the surface used to construct a boardwalk over sand on barrier islands. Laying deck or throwing deck refers to the act of placing and bolting down cold-formed steel beneath roofing and concrete floors. This is usually done by an ironworker, sometimes in conjunction with a cement mason or carpenter. It regarded as one of the most ...

5. Cellular floor raceways - Wikipedia

   en.wikipedia.org/wiki/Cellular_floor_raceways

   Cellular floor raceways are electrical wiring ducts or cells made from steel floor deck that serve as structural formwork for placement of concrete floor slabs and also as wire and cable raceways within the concrete floor slab.

6. Orthotropic deck - Wikipedia

   en.wikipedia.org/wiki/Orthotropic_deck

   The orthotropic deck may be integral with or supported on a grid of deck framing members, such as transverse floor beams and longitudinal girders. All these various choices for the stiffening elements, e.g., ribs, floor beams and main girders, can be interchanged, resulting in a great variety of orthotropic panels.

7. Open web steel joist - Wikipedia

   en.wikipedia.org/wiki/Open_web_steel_joist

   The CJ-Series Joists are capable of supporting larger floor or roof loadings due to the attachment of the concrete slab to the top chord of the composite joist. Shear connection between the concrete slab and steel joist is typically made by the welding of shear studs through the steel deck to the underlying CJ-Series Composite Steel Joist. [2]
