Steel Decking

Structural Diagram — How Steel Decking Works

This diagram illustrates a complete composite steel decking floor assembly. The profiled steel deck sits directly on the steel beam support, acting as permanent formwork that carries wet concrete load until the concrete topping cures. Once hardened, the concrete topping and steel deck work together as a composite steel decking system, distributing structural load evenly across the floor.

System Structure:

• Concrete Topping – Provides structural strength and load distribution
• Profiled Steel Deck – Acts as permanent formwork, adding strength before concrete hardens
• Steel Beam Support – Delivers primary structural support for the composite floor system

System Benefits:

• High Strength – composite action provides superior load capacity
• Fast Construction – steel deck acts as formwork, reducing labor and construction time
• Cost Effective – reduces labor, formwork, and material costs
• Lightweight – reduced dead load compared to traditional concrete systems
• Fire Resistant – concrete topping provides excellent fire resistance
• Sound Insulation – concrete mass helps reduce noise and vibration

Applications:

• Commercial Buildings
• Industrial Facilities
• Warehouses
• Parking Decks
• Bridges
• Multi-Storey Structures
