Steel truss roof structures consist of rods connected by hinges at each end, forming planar or spatial structures with triangular elements. This design primarily subjects members to axial tension or pressure, optimizing material strength. Compared to solid web beams, truss structures offer material savings, reduced dead weight, and increased stiffness for large spans.
Our comprehensive service includes design, fabrication of all structural components (steel columns, beams, purlins, etc.), and complete installation including panels, windows, and doors.
