What is steel deck

What is steel deck? As steel deck specialists, in this knowledge article we take an in depth look at what steel deck is, it’s many advantages, what profiles and span capabilities are available and the main benefits of specifying steel deck for construction projects. Steel deck is also known as steel deck, corrugated steel deck or ‘the profiled steel plates’.

What is steel deck

Steel deck, also known as steel deck, the galvanized steel plate that is pressed and formed by the pressing machine becomes the steel deck. Steel decks include steel floor decks for composite floors, steel roof decks, and steel wall decks.

Composite steel deck is perfect for use in both floor and roof construction because it has a high strength-to-weight ratio. Other advantages of steel deck include uniform quality, proven durability including excellent fire performance and cost efficiency.

Why is steel deck corrugated

As the load-bearing member of the structure, the steel deck uses the corrugation of the steel deck to improve the bending strength of the plate, which enables the steel deck to provide greater resistance to bending moments whether it is subjected to vertical loads or wind loads.

The difference in the corrugation of the steel deck determines the difference in the section properties of different steel deck types, which also determines the different force performance under different working conditions. A variety of steel decks provided by Solideck will be used according to different project situations and come with instruction manuals.

What is a steel deck composite floor slab

Steel deck is commonly used in conjunction with reinforced concrete to create a steel deck composite floor slab.

Each of the sheets is fixed to the top flange of the beam with shear studs using ‘thru-deck ‘or ‘straight to steel’ stud welding techniques. The shear studs create a composite action between the steel beams and the concrete.

Composite steel deck has embossments designed to interlock with concrete slabs. The combination of floor deck and concrete serves the dual purpose of permanent form and positive reinforcement.

Why is steel deck painted

The steel deck is a stressed component, whether it is steel floor deck or steel soor deck. In order to ensure the mechanical performance of the steel deck, the steel deck must be protected against corrosion, or in order to make the steel deck more beautiful, the steel deck needs to be ” paint”.

The “painting” of the steel deck includes two types, one is to simply galvanize the steel deck, and the other is to perform color painting on the steel deck in addition to the galvanized treatment. Both treatments enhance the durability of the steel and extend the life of the steel deck. And the second treatment method increases the aesthetic effect of the steel deck.

How far can steel deck span

The length of steel deck spans will depend upon the type of steel deck and manufacturer specifications.

One indicator of how far steel deck can span is its depth. Typically, a deeper type of steel deck, such as SD76 or SD66 composite deck, will be able to span further than shorter depth steel decks, like SD38 or SD51 composite deck.

Some other factors that affect steel deck span are the deck gauge, steel grade, and, for steel floor deck, slab depth.

Deck gauge is the measure of the thickness of each steel deck profile. steel deck with a thicker gauge will be able to span farther than steel deck with a smaller gauge.

When it comes to steel grade, steel deck with a higher grade will typically be able to span farther than steel deck with a lower grade. such as S340, will be able to span further than the lower, like S280.

Steel decks of the same gauge and grade can span farther with smaller slab depth than with larger slab depth.
