With a view to satisfy requirements of construction buildings with long spans ( > 40m) such as sports complex, workshops and roofs, introduction of spaced/overhead roof frame shall be optimum solution for combination between aesthetic and costs aspects. Spaced roof frame shall be constructed on the basis of one element generated into three directions, of one frame element there shall be connecting points and bracing bars.

Apart from common ball bearing/coupling with high costs, we also implement connecting points by bolts fastening at pipe ends. By this solution and through practical experiences construction costs might be reduced by 30% in comparison with Zamail typed roof frame. Average mass of spaced roof frame with span of 20m¸ 50m shall be 8.5kg/m² against 11 kg/m²¸ 22kg/m² of Zamail ones.
