Deck

Controlled Deck Zone (CDZ) is a designated safety area used during metal deck installation in steel construction, mainly recognized under OSHA rules. What it Means: A CDZ is an area where workers are allowed to install metal decking without conventional fall protection systems (like guardrails or personal fall arrest systems) under strict conditions. Purpose: It helps workers place and secure decking efficiently while reducing fall risks during initial deck placement. Control

Shear studs are welded through the metal deck to the top flange of a steel beam. The section above the deck is embedded in concrete, allowing it to transfer shear force between the slab and the beam. These studs are utilized in composite construction so that the concrete slab and steel beam function together as a single, stronger structural unit. Typical arrangement: Steel beam at bottom Metal deck placed over beam Stud welded through deck into beam flange Part of stud projec

A deck support angle is a structural steel angle section employed to support metal decking, such as roof or floor decks, at edges, openings, or transitions. Common Uses of Deck Support Angle: Perimeter edge support:- Installed along beams/walls where deck sheets end. Opening reinforcement:- Around openings for stairs, ducts, pipes, skylights, etc. Change in elevation:- Where deck levels step up/down. Deck-to-wall connection:- Provides seat support when deck meets concrete or

A steel angle or bent plate, used around the perimeter of a floor or opening to contain the concrete during placement. The SDI pour stop selection tables are published only up to a 12-inch slab overhang. For overhangs greater than 12 inches, SDI does not provide a standard gauge selection; the edge must be engineered (e.g., heavier gage, added stiffeners, or reduced overhang) based on project loads and support conditions. Pour stop at slab edge

Composite steel floor decking includes a specific steel deck profile that serves as a mold for constructing a structural concrete slab, with the steel deck providing moment reinforcement. This steel deck incorporates embossments, interlocking profile geometry, or other mechanisms for horizontal shear resistance, creating a mechanical bond between the steel deck and concrete. This bond allows the slab to withstand vertical and diaphragm shear loads together. Before achieving c

A steel deck is a cold-formed, corrugated steel sheet used as a structural platform in floors or roofs. It’s often paired with concrete (composite deck) or used alone as a roof deck. Its fluted profile increases strength while keeping weight low, making it cost-effective and quick to install. Steel deck nomenclature Steel deck
