Description
Quick Details
LARGE-SPAN TRUSS ROOF SYSTEM
A truss is a lattice structure composed of members connected at joints within a plane. It utilizes the geometric stability of triangular units to convert external forces into axial forces (tension or compression) within the members, allowing for large spans with minimal material use.

TYPE OF SPACE GRID STRUCTURE

Space Frame Truss
Uses circular or square tubes with intersecting welds.
Three-dimensional force distribution for high efficiency and stability, with a modern aesthetic.
Ideal for large-span spatial structures.

Triangular Truss
Triangular grid with excellent geometric stability.
Classic and robust design; simple to design and construct.
One of the most widely used truss types.

Arch Truss
Curved top chord for optimal force distribution.
Material-efficient and suitable for long spans.
Elegant in form, combining both aesthetics and functionality.
CORE ADVANTAGES OF SPACE GRID STRUCTURES

Ultra-Large Span
Single spans can exceed 200 meters.
Tubular truss structures offer high rigidity, making them ideal for extremely large and heavy roof systems.
Cost-Effective
Saves 15–20% more steel compared to space frames.
Trusses are composed of linear elements, often requiring less steel, making them a more economical choice.


Fast Construction
Segmental lifting reduces construction time by 30%.
Trusses are typically prefabricated in large segments at the factory and lifted into place on-site, minimizing on-site work and reducing the number of lifts required.
Versatile Forms
Supports straight, arched, and fish-belly shapes.
Tubular trusses are especially suited for smooth, large-radius curves such as arches or saddle shapes. The fish-belly form features a curved bottom chord, offering both structural efficiency and aesthetic appeal.
