Multi-Floor Deck Slab Structures

Multi-Floor Deck Slab Structures (Steel + RCC Composite Buildings)

We specialize in the execution of multi-floor deck slab structures, combining the strength of structural steel with the durability of RCC to deliver efficient, scalable, and high-performance buildings. These systems are widely used for hospitals, institutional buildings, commercial complexes, hostels, and industrial facilities, where speed, flexibility, and structural efficiency are critical.

In this system, steel beams and columns form the primary load-bearing framework, while profiled metal decking acts as permanent shuttering for RCC slab casting. This composite approach reduces construction time, optimizes material usage, and allows seamless integration with existing structures—making it highly suitable for vertical expansions and live-building modifications.

Key Advantages:

Faster Construction: Eliminates conventional shuttering, enabling quicker slab casting and reduced project timelines
Reduced Dead Load: Steel structure significantly lowers load on existing foundations, ideal for vertical expansion
High Structural Efficiency: Composite action between steel and concrete enhances load-carrying capacity
Minimal Disruption: Suitable for execution in live operational environments such as hospitals and institutions
Future Expandability: Designed for additional floors or modifications without major structural changes

Scope of Work:

Structural steel framework (columns, beams, bracing)
Deck sheet supply and installation
RCC slab casting with reinforcement

Staircases, lift structures, and service platforms
Integration with existing building (retrofitting / extensions)
Civil foundations and strengthening (if required)

Technical Approach

Our execution involves precise coordination between structural design, fabrication, and civil works:
Fabrication and erection of steel columns and beams (E250 / E350 grade)
Installation of profiled metal deck sheets as permanent shuttering
Placement of reinforcement and RCC slab casting (typically 100–150 mm thick)
Integration with existing RCC structure through anchoring and load transfer systems
Use of shear connectors (if required) for enhanced composite actio

Where It Is Used

Hospital expansions and additional floors
Institutional buildings and hostels
Commercial complexes and office buildings
Industrial mezzanine and production floors
Retrofit and strengthening projects

Our Execution Strength

Proven experience in multi-floor expansion over existing buildings
Ability to execute projects in running facilities without shutdown
In-house fabrication ensuring quality and dimensional accuracy
Strong coordination between steel and civil teams
Execution as per IS / international design standards

Conclusion

Multi-floor deck slab structures offer a modern, efficient alternative to conventional RCC construction, especially where speed, load optimization, and adaptability are required. With our integrated approach to engineering, fabrication, and civil execution, we deliver buildings that are structurally sound, time-efficient, and ready for future growth.
