Description
Open-web Steel Floor Deck
Open-web steel floor decking is a widely used flooring material in steel structure buildings. Common specifications include 750, 720, 600, and 915 series, primarily applied in industrial and civil constructions such as factories, warehouses, workshops, commercial complexes, office towers, hotels, and multi-story/high-rise buildings.
Functional Features
Construction Support:
Serves as a permanent formwork during concrete pouring, replacing traditional wood or bamboo templates. Provides a stable platform for construction loads.
Structural Load-Bearing:
Integrates with concrete to form a composite floor system, enhancing overall stiffness. The ribbed design of the steel deck effectively distributes loads and improves crack resistance.
Utility Integration:
Facilitates concealed routing of electrical, HVAC, and plumbing systems. Embossed or anti-slip surfaces enhance concrete bonding, preventing delamination.
Advantages and Characteristics
High Construction Efficiency:
Factory-prefabricated, installed on-site without formwork removal. Reduces labor, material handling, and project timelines.
Cost-Effectiveness:
Eliminates temporary formwork and supports, lowering total costs. Reduces floor self-weight, minimizing load on steel beams/columns and steel consumption.
Corrosion Resistance:
Protected by galvanized or anti-corrosive coatings for long-term durability.
Key Features
Open-web steel floor decking is the preferred choice for steel structure flooring due to its rapid installation, economic benefits, and optimized load-bearing performance. Its core value lies in combining formwork functionality with structural load-bearing capacity, ensuring both construction efficiency and building performance. Suitable for diverse floor engineering projects across various spans and industrial/standardized applications.
Closed-web Steel Floor Deck
Closed-web steel floor decking, similar to open-web decking, is primarily used in floor systems for industrial plants and commercial buildings. Compared to open-web decks, it offers greater sectional moment of inertia, enhanced stiffness, higher load-bearing capacity, and improved fire resistance.
Material and Specifications
Models: 790, 740, 660 series, etc.
Material: Hot-dip galvanized Q235 or Q355 steel.
Thickness: 0.8–1.5 mm.
Rib Height: 50–150 mm.
Effective Width: 500–800 mm.
Customizable models to meet specific project requirements.
Key Features
Corrosion Resistance:
Galvanized coating protects against moisture, acid-alkaline environments, and chemical exposure, making it ideal for chemical plants.
Composite Action:
Forms a steel-concrete composite slab with cast-in-place concrete, leveraging steel’s tensile strength and concrete’s compressive strength to optimize structural efficiency.
Reusability:
Certain designs allow for demountable and reusable decking, facilitating future renovations or material recycling.
Advantages
High Load-Bearing Capacity: Ideal for large spans and heavy loads.
Fire Resistance: Enhanced performance due to closed-web design.
Cost and Time Savings: Rapid installation reduces labor and construction timelines.
Lightweight Efficiency: Minimizes structural load on beams and columns, lowering steel consumption.
Core Benefits
The closed-web design significantly improves mechanical performance through its optimized cross-section, while the composite interaction with concrete ensures structural integrity. These features make it a superior solution for projects demanding high spans, heavy loads, fire safety, and construction efficiency. Suitable for diverse applications ranging from industrial facilities to high-rise buildings.
Truss Composite Floor Deck System
A truss composite floor deck system consists of a reinforced steel truss and galvanized base plate, integrated via welding or bolting. The universal model, TD3 Series, is primarily used in large-span public buildings such as industrial plants, logistics warehouses, commercial complexes, convention centers, and stadiums.
Functional Features
Structural Role:
Reinforced Steel Truss: Acts as the load-bearing skeleton, supporting concrete self-weight and construction loads.Galvanized Base Plate: Serves as permanent formwork.
Load Distribution:
Top Chord Reinforcement: Integrates with concrete to share service loads.Bottom Chord and Web Members: Provide tensile and shear resistance, enhancing structural stability.
Core Advantages
Ultra-High Load Capacity and Large Span Capability:
Converts bending moments into axial forces within truss members, achieving 50% greater spans than traditional floor decks under equivalent loads.
Typical Span: 4–6 meters; Maximum Span: 8 meters.Minimal mid-span deflection due to optimized force distribution.
High Construction Efficiency:
Eliminates Formwork Installation and Removal: Base plate functions as permanent formwork, reducing scaffolding work by 80%.
3–5x Faster Installation: Compared to cast-in-situ slabs.
Modular Assembly: Panels are connected via welding or bolting, ideal for prefabricated construction.
Material and Cost Savings:
Reduced Concrete Usage: Truss webs eliminate the need for concrete filling, enabling thinner slabs and lower self-weight.
Optimized Reinforcement: Prefabricated truss reinforcement replaces partial cast-in-situ rebar, minimizing material waste.
Superior Fire and Acoustic Performance:
2+ Hour Fire Resistance: Achieved by fully encasing truss reinforcement in concrete.
Enhanced Sound Insulation: High slab stiffness combined with elastic supports or acoustic materials reduces impact and airborne noise transmission.
Design Flexibility:
Utility Integration: Flat or grooved base plates allow concealed routing of electrical/HVAC systems within truss gaps.
Demountable Design: Specialized joints enable post-construction disassembly for functional upgrades (e.g., equipment installation, floor openings).
