Monotubular Tower

Seccional has proprietary software that allows total security and precision in the dimensioning of its projects, evaluating the stresses and strains in the assembly and operating states, beyond the ultimate limit state through Finite Element Modeling. The software validations were carried out in the laboratories of the Federal Technological University of Paraná-NuPES Simultaneous Engineering Research Center and of the Positivo University-NuTEC Technology Development Center.

Wind tunnel tests were carried out at the Laboratory of Aerodynamics of Constructions LAC - Federal University of Rio Grande do Sul and at the National Research Council of Canada, which validated the effectiveness and better Federal of Rio Grande do Sul and at Natfona/Research the aerodynamic behavior of the Sectional towers.

To ensure total efficiency and durability, the products are put to the test through destructive tests in laboratories such as the Paraná Institute of Technology TECPAR and the Central Laboratory of the State LACTEC, in addition to certified test stations. In this way, it achieves the excellence and guarantee the structures offered.

Seccional chose to work with patinatable steel type, which has a yield limit of 375MPa, much higher than the conventional steel ASTM A36 with 250MPa. This special steel has small alloy contents, such as copper, chromium, phosphorus, niobium, which promote the formation of a compact and adherent oxide film on its surface. This film, called patina, acts as a barrier between the steel and the corrosive environment, protecting the structure against corrosion caused by weather changes and aggressive environments. Additionally, the structures are hot-dip galvanized in accordance with NBR 6323. It is the safety of durability that Seccional insists on guaranteeing.
