Mixed vs. Conventional Construction

Why choose composite construction over conventional construction.

(mixed versus conventional)

The way of construction of the composite construction from metal frame is far superior to the conventional constructions, it offers reduced IKA-less number of working hours and high construction speed.

  • Architectural flexibility compared to conventional structures that do not have the capacity for large openings. impossible in reinforced concrete structures.
  • Superiority in the degree of seismicity – The structural elements of metal structures are produced in industrial units that fully meet the required specifications. In all other constructions (concrete, stone, wood, etc.) the strength is checked at the construction site or in a laboratory. Therefore only structural steel has a specific strength, uniform and stable, ie it is a more reliable material. This is also taken into account by the regulations on safety factors. Due to its superstructure, ie the many points – nodes that connect the frame, it is provided more security statically and this because even if there is a failure at one point (which practically does not happen), the building is hardly affected at all. Unlike in a conventional building, collapse would be inevitable. The elements of the prefabricated building are made in a special covered space and then transported to the construction site for installation and welding. metal structures are lighter than conventional ones. This has the following advantage. The action of an earthquake in a building depends on a seismic factor and the mass of the building, therefore its weight. Therefore, the lighter a structure is, the less stress it exerts during an earthquake and the less permanent deformation it receives.
  • In a composite structure, even in the event of damage after an earthquake, replacing a member (Metal column-Metal beam, etc.) is a process of a few days, compared to conventional structures where when a member (Kolona – Dokari) is damaged by the earthquake, it is destroyed and there the restoration of damages is impossible.
  • Because they are light constructions they are suitable for use in additions to existing buildings which is impossible in prefabricated buildings (Prefabricated houses). In most cases, reinforcement of the existing building is not required due to the low weight of the metal frame and the construction materials (YTONG masonry, dry construction, etc.)
  • Smart Building after years of experience and research in the field of construction and in collaboration with the National Technical University of Athens (NTUA) has established in its construction the external thermal insulation. External thermal insulation achieves excellent energy indicators based on the restrictions established by KENAK in recent years on building permits. The Thermo Facade embraces the building externally so that changes in the outside temperature find an obstacle and do not pass to the building materials, which have no thermal insulation properties by themselves, something that happens in the prefabricated buildings (Prefabricated houses) where the insulation is in the middle. of masonry.
  • Provides a reduced contribution to IKA stamps (50% less than the conventional one).
  • High manufacturing standards – In composite construction, metal components are manufactured in the factory under human and computer monitoring. The steel production criteria follow international standards, bearing certifications (ISO) and are also controlled by state bodies. Otherwise in conventional construction the strength is checked at the construction site or in a laboratory. Therefore only structural steel has a specific strength, uniform and stable, ie it is a more reliable material.
Examples
  • The delivery time required for a metal house of 100-120 m2 is 90 – 150 working days.
  • Requires lower foundation costs due to lower loads.
