Steel Deck (also referred to as Profiled Steel Sheet or Steel Support Plate)
Steel deck represents a wavy sheet material that is crafted through the processes of roll - pressing and cold - bending galvanized steel sheets or galvalume steel sheets. It collaborates with concrete to create composite floor slabs.
Classification of Steel Deck by Structural Form
- Open - Ribbed Steel Deck: The ribs of the plate are open (e.g., YX series). Concrete can fully envelop the ribs, resulting in a robust bond. This type is ideal for conventional concrete floor slabs and high - rise construction projects.
- Closed - Ribbed Steel Deck: The ribs are enclosed, and the bottom surface is smooth and flat (e.g., BD series). It boasts exceptional fire resistance and eliminates the need for additional ceiling installations. It is well - suited to places with stringent fire safety requirements, such as hospitals and shopping malls.
- Reduced - Ribbed Steel Deck: It features relatively low rib heights and closely spaced waves, which helps save on concrete consumption and offers high cost - efficiency. It is a great choice for light industrial workshops and temporary structures.
- Steel Bar Truss Floor Deck: It incorporates built - in triangular steel bar trusses, eliminating the need for formwork and steel bar tying, thus significantly accelerating the construction speed. It is highly suitable for large industrial workshops and prefabricated buildings.
Classification by Material
- Galvanized Steel Sheet: The base material is galvanized steel (with a zinc coating of 60 - 275 g/m²). It is cost - effective but has average corrosion resistance.
- Galvalume Steel Sheet (AZ150): Its corrosion resistance is 2 - 6 times greater than that of galvanized sheets, making it an excellent option for humid environments.
- Stainless Steel Deck: It is employed in situations with special corrosion - resistant demands, such as chemical plant buildings.
Common Specifications of Steel Deck
- Plate Thickness (mm): Ranging from 0.5 to 1.5 (commonly 0.8, 1.0, and 1.2)
- Rib Height (mm): Between 35 and 120
- Effective Width (mm): From 600 to 1000 (adjustable according to the wave peak spacing)
- Length (m): Customizable (usually not exceeding 12 m)
Production Process of Steel Deck
- 1.Base Sheet Preparation: Utilize galvanized/galvalume steel sheet coils.
- 2.Roll - Forming: Press out the wavy rib heights using a continuous cold - bending machine.
- 3.Cutting: Trim the sheets to the designed length.
- 4.Packaging: Bundle them to prevent scratches and attach labels indicating the model, thickness, and length.
Advantages and Disadvantages of Steel Deck
- 1.Advantages
- Fast Construction: Compared to traditional wooden formwork, it can save over 50% of the construction time.
- Cost Savings: It reduces the consumption of formwork and supports.
- Lightweight Structure: It helps lower the building load.
- Environmentally Friendly: It is recyclable and minimizes construction waste.
- 2.Disadvantages
- Corrosion Protection Required: The damaged galvanized coating needs to be touched up with anti - rust paint.
- Poor Sound Insulation: Additional sound insulation materials are necessary.
