This is a unidirectional composite slab in which concrete is poured onto a corrugated sheet profile that serves both as formwork and as positive framework. Once the concrete sets, this profile collaborates absorbing the tensile stresses.

This type of slab was first used in the U.S. in the 50's for the construction of skyscrapers as it can be constructed without the use of props. Since then, its use has extended throughout Europe (late sixties) until the present day.

Composite sheet slabs support both repetitive and abrupt static and mobile loads that do not exceed the limits indicated in the current building regulations.

Although they are specially designed for installation on metallic structures, they may also be used on concrete, wood or masonry structures.

This type of slab is suitable for a wide range of applications:

• Housing
• Industrial buildings
• Car parks
• Offices
• Public buildings
• Shopping and leisure centres
• Warehouses
