The main beams are executed with constant or variable section depending on the solution of draining water of the roof. In turn both types can have I or T cross section depending on the hall’s opening and loads at the roof level. The connection with the structure’s columns is made bay dry mechanical fixing. By using quality concrete (class up to C60/75) and prestressing can be obtained elements with low tare weight.
Secondary beams (purlins) and marginal beams can be made also prestressed with rectangular, trapezoidal or T section. The length and the connection with the rest of the structure are determined separately for each structure.
Bridge beams are assimilated from the IPTANA products range for various spans and loads, with I and T sections, with spans between 12 and 24 meters. As catalogue products can be modified and adapted in the acceptance limit of the designers.
