Product Overview
A Double-Layer Space Frame Structure is a three-dimensional structural system consisting of top chords, bottom chords, and web members arranged into interconnected layers.
The upper and lower grids work together through diagonal web members to create a highly stable framework with excellent rigidity, load distribution, and structural efficiency.
Compared with single-layer roof systems, double-layer space frames offer greater strength, enhanced safety, and broader application flexibility, making them one of the most widely used solutions for large-span roofing projects worldwide.
