Use of sheds and abat-jours is one of the most simple and cost-effective ways of adding more original entourage both to the external appearance and the interior design of buildings in the modern architecture. Nevertheless, besides their esthetic purpose, these structures have to fulfill their natural functions – protection from climatic exposure. Preventing from the negative impact of the atmospheric precipitations and solar radiation, the sheds at the same time do not limit the natural lighting and movement of the airflows, providing for comfortable conditions. The sheds are most commonly used in the elite suburban and cottage building.
The shed frame is fixed on supports such as metallic posts, and the abat-jour is fixed directly on the wall of the building. As a rule, this is light welded metal ware made from shaped tubes of square and round cross-section and covered with sheet metal (sheets, professional decking or cellular polycarbonate).
The simplest way is using the galvanized sheets or the professional decking, the service life of such structures is up to 15 years. The same elements made from stainless steel will serve many times longer, yet their major drawback is their high price.
The optimum option for covering the abat-jours and sheds is the cellular polycarbonate. This is a modern material, as stable as metal, impeding the harmful ultraviolet radiation, and letting at the same time to pass the light. The range of working temperatures for the polycarbonate is -50ºС to + 150ºС, and the actual service life reaches 20 to 25 years.
But the most important advantage of the cellular polycarbonate is its lightweight (many times lighter than the metals) which enables to use lighter profiles for the calculated structures, which reduces the general, use of metal and increases the safety of structures.
Construction of sheds and abat-jours consists of three stages. At the stage of design, the designers elaborate the technical documentation, taking into account the design documentation for the building and the wishes of the customer, at the same time, all possible factors are taken into account, including the wind and snow loads on the structure. The next stage is manufacturing of the structure and its elements suitable for transportation. The last stage is its final mounting at the site.
