The advantages of composite flooring are based on the structural interaction between a profiled steel deck and an in-situ cast concrete slab. Both materials work together to form a lightweight, strong, and durable composite slab, optimizing resource use and the overall performance of the system.
During the construction phase, the composite floor profiles acts as permanent formwork, replacing traditional shuttering. It is capable of supporting the weight of fresh concrete and construction loads, reducing or eliminating the need for propping depending on configuration and structural calculation. In addition, it provides a stable surface that facilitates work organization and continuity.
Lightweight and Structural Performance
The system enables the construction of structures with reduced self-weight while maintaining adequate stiffness and load-bearing capacity. The design of the ribbed profiles and their embossments ensures load transfer between steel and concrete, allowing the section to act compositely under bending, shear, and longitudinal forces.
This structural optimization results in improved use of both steel and concrete, as well as a reduction in loads transmitted to the primary structure and foundations.
Versatility and Project Adaptation
Incoperfil composite flooring is compatible with steel, concrete, or composite structures, allowing the design of horizontal and sloped slabs, cantilevers, or solutions integrated within beams.
The system accommodates different slab depths, spans between supports, and fire-resistance levels, always according to structural calculations and applicable building codes.
The range of Incoperfil composite profiles includes:
INCO 70.4 Composite: indicated for shallow slabs and lightweight solutions.
INCO 100.3 Composite: designed for medium spans in configurations without intermediate propping, subject to structural verification.
INCO 100.3 R Composite: a variant aimed at higher fire-resistance requirements and specific structural performance needs.
Profile selection must be carried out through structural analysis in accordance with current regulations.
Integration in Composite Structures
Incoperfil composite profiles are compatible with standard shear connector systems for steel–concrete composite structures. This allows the slab to collaborate with steel beams in the overall structural resistance, improving structural efficiency and optimizing member sizing.
Sustainability and Durability
Manufactured in galvanized steel in accordance with UNE-EN 10346, the profiles ensure adequate corrosion protection and a long service life under normal exposure conditions.
The reduction in self-weight and the simplification of the construction process contribute to more efficient use of materials and resources, promoting rationalized structural solutions.
Conclusion
The advantages of IncoPerfil composite flooring position it as an advanced and efficient structural solution. This type of flooring combines speed of execution, structural efficiency, and construction versatility into a single technical solution. Its steel–concrete composite behavior, its ability to adapt to different structural configurations, and the optimization of self-weight consolidate it as a suitable alternative for industrial, commercial, and residential buildings.
