Composite floors



The wide range of Arval floors makes it possible to adapt to all site conditions and the technical needs of the client.
All the systems combine mechanical strength, ease of installation, safety,and compatibility with the structures and networks.
Their acoustic and thermal functions are optimised through an innovative combination of various materials: steel, concrete, rock-wool, plaster and wood.
Several Arval steel floor families are available to meet every type of need.

The combination of steel and concrete, created using special rib and stud forms, provides substantial savings over the laying of floors of equal performance using traditional solutions and is also a quicker and completely safe implementation.


Composite floors Cofrastra:
high-adhesion

Composite flooring opens up a multitude of usages, constructions and designs for investors, architects, main contractors and assembly companies.
The classic advantages of compositebuilding, such as higher industrial prefabrication, high flexibility of use, short building times and high load carrying capacity are also the primary advantages of the COFRASTRA composite flooring systems.

IMPLEMENTATION

Rapid progress of building-site work
The steel floors are manufactured to the lengths specified on the order according to a slab layout plan and then delivered on pallets. The quick and easy implementation takes place in several expertly handled sequences by assembly teams.
A safe working platform
The steel floor is ready to use and can be walked on as soon as it is fixed. It constitutes a working platform providing perfect safety conditions. The floors create an efficient and sealed formwork and the under side remains clean. The floor openings are placed before pouring with no need to drill the floor. The lack of an open cavity optimises safety on site
Well organised building sites
Several storeys of floor can be prepared in advance. For mixed steel-concrete floors, sequential pouring over several storeys can be designed for installation without props. The Arval steel floor systems improve the consistency of the schedule from the basements to the roof terrace. Allows completed floors to be put into use earlier whilst allowing ongoing development of other levels
