Steel Space Frame Structure (Bolt Connection)

Product Overview

Our Steel Space Frame Structure (Bolt Connection) is a lightweight yet high-strength structural system designed for large-span roofs and complex architectural forms. Using a bolted connection system, the space frame ensures fast installation, precise assembly, and excellent structural performance. It is widely applied in public buildings and industrial facilities requiring large column-free spaces.

Key Features

Large-Span Capability
Suitable for long-span and wide-area coverage with uniform load distribution and high structural efficiency.

 Bolted Connection System
Enables fast on-site assembly, easy disassembly if required, and reduced site welding work.

Lightweight & High Strength
Optimized spatial force distribution reduces overall steel consumption while maintaining high load-bearing capacity.

Flexible Architectural Design
Supports flat, curved, domed, and irregular geometries to meet architectural and functional requirements.

High Assembly Accuracy
Factory-prefabricated components ensure precise node connections and reliable structural performance.
