The specifications and sizes of floor decks typically vary based on specific engineering designs and requirements. The following is a general range of commonly used floor deck specifications for reference only:

Deck Thickness: The thickness of the deck board typically ranges from 20mm to 80mm, with the specific thickness depending on design loads, spans, and usage requirements, among other factors.

Decking Width: The width of the decking typically ranges from 200mm to 1000mm, determined by the specific project requirements and design parameters.

Span: The length of the floor deck typically ranges from 2000mm to 6000mm, and may vary depending on different design and construction requirements.

Commonly used floor deck materials are carbon structural steel or alloy structural steel, offering excellent strength and load-bearing capacity.

Profile and Structure Design: The floor deck features various槽 shapes, including U-shaped, Z-shaped, and wedge-shaped, with suitable structural designs selected based on different load-bearing requirements and application scenarios.

Surface Treatment: Decking panels can be treated for corrosion resistance as needed, such as hot-dip galvanizing, applying rust-proof paint, etc., to extend their service life and enhance their aesthetic appearance.

Other special requirements: In accordance with specific engineering needs, there may be additional special requirements or customization needs for the specifications and dimensions of the floor deck, which should be determined based on the actual situation.

Note that the above size range is for reference only. The actual specifications and dimensions of the floor deck should be determined based on the specific engineering design, load requirements, and construction conditions, which should be assessed and confirmed by professional engineers or designers.
