"EUROHOUSE-Bulgaria" Ltd. is the only one throughout the country to produce metal roofing constructions of the "PYRAMID" type. With this type of construction can be built and planned buildings as: halls, sheds, bazaars, market-places, parking-lots, stadiums, riding-halls and many others, in which the lighted distance can be more than 30 metres, which is a more economically favorable variant of a standard hall. A three-dimensional connection, the base for the pyramid's solidity, comprises a three-dimensional progression, which compresses the elements' stress . The form of the spatial part is a tetrahedron and has four constituent parts. A spatial frame of this type of connection shapes a very strong, thick and flexible structure that can be used horizontally or unfold into many forms. The beauty of the pyramid in the pipe diagonals gives a structural clarity. The connection of the "PYRAMID" type is a hard construction joining supports in a geometric practice. Constructions of this type are used for spatial constructions with the purpose of achieving to the highest degree long and wide constructions with several supports. The strength is obtained through the built-in strong connection of the triangular frame. All moments of yielding are conveyed as stress which the compression holds back along the length of each support. The assembly of this type of roof constructions is done considerably faster, i.e. for about 30 percent less time than it takes for the traditional halls and buildings. For example, a metal construction of this type with an exemplary total built-up area of 1000 square meters can be finished within the range of sixty work days. In comparison with a building of a different type, the second would be in the initial building stage at this time. "EUROHOUSE-Bulgaria" Ltd. has at its disposal a highly qualified engineering and technical team in the field of planning and construction of industrial metal buildings. A stronger and clearer form is composed in connecting pyramids in which all the supports have the length of a unit. In technical aspect this is described as an isotropic vector matrix or in width for a connection unit in an octet. The technology for the company's production and equipment gives the opportunity for the production of metal constructions and equipment in accordance with all the norms and standards. More complicated variants change the supports' length which bend the general structure of the pyramid, or can contain other geometric shapes.
