1.Metalliko SpitiThe composite construction is a modern building method that is based in the combination of steel cross sections and reinforced concrete elements and is aimed at the maximum possible utilization of their properties to the benefit of the structure.

Advantages versus conventional

  • Provides an anti-seismic shield. The supports and beams have been replaced by structural steel cross sections the can provide an anti-seismic shield for the building.
  • Ensures constant and high level construction specifications due to the use of industrial elements.
  • Provides freedom of architectural design. Allows the design of large uniform spaces without any intervening support structures.
  • It is recommended for the construction of high rise buildings without the use of large cross sections.
  • Favors the vertical expansion, due to smaller weight.
  • Requires a shorter time of delivery (approximately one half of the conventional)
  • Provides a reduced contribution in social security stamps (50% less than conventional).
  • Requires a lower cost for foundation due to smaller loads borne.
  • Because the specific construction method is recommended worldwide and in Greece and in particular, in areas with a high seismic activity due to the high strengths in case of earthquake.
  • There is no transportation cost involved (in the case of composite construction, the metal framework is built at the job site and can be erected with a few hours at the project site).
  • Easy restoration of damages.
  • It is the building method that was used in all of the major Olympic projects.

Time of Delivery

The time of delivery required for a house of area 100-120 m2 is 90 – 150 working days.


The price offered by our company, suggestively, starts from 820,00 €/m2 and can be configured based on the needs and options chosen by the customer.

Construction Method

  • Load – Bearing Structure

5.Metalliko SpitiThe system consists of a metal framework (supports, beams), which are connected with each other and constitute the load bearing structure of the building. The cross sections arise following the structural (static) resolution of the load bearing structure, in accordance with the Euro-Codes and they are open or closed cross sections (profiles).
The slabs are constructed from reinforced concrete and it may be concreted (laid) in wood shuttering (exactly as in the conventional construction) or metal shuttering made from trapezoid sheet metal. The solid slab is then coated with plaster. In the case of preliminary slabbing, it is simply coated. The collaboration of the structural steel elements and concrete is achieved through spikes at the main beams that prevent the concrete from sliding. Under the metal shuttering is placed plaster board for the indoor spaces and cement mortar board or drywall plasterboard for the exterior spaces

  • Masonry Walls


Walls with Ytong

Ytong is an industrial material with thermal insulation properties. The wall masonry is running type and constructed in situ by building of the elements and intervention of headers, every 1 m. approximately vertically. Due to the properties of this material there is no need for additional insulation. The final surface is configured by mortar coating, which is 12,5-15 cm thick for interior walls and 25 cm for the exterior walls.

Industrial panel walls

The industrial panel is a building element consisting of two parallel lattices and a sheet of self-retardant foamed polystyrene between them (“sandwich”). The two lattices are held together parallel to one another using bidiagonal galvanized bars. Upon their placement and securing between the metal supports, follows gravel-crete shot layer and mortar layer. The final thickness of the wall is 15 cm for interior walls and 25 cm for exterior walls.
