The Prefab Steel Warehouse Space Frame Structure is a high-performance, long-span roofing and building system designed for modern industrial warehouses, logistics distribution centers, manufacturing plants, and storage facilities that require large open spaces with maximum structural efficiency. Engineered using advanced space-frame technology and modular prefab steel components, this structure delivers exceptional strength, fast installation, and long-term durability while maintaining a competitive overall project cost.

This warehouse structure is built on a three-dimensional triangular or square pyramid space-frame system, which distributes loads evenly and enhances resistance to various environmental forces, including wind pressure, snow load, seismic impact, and roof loads from stacked materials or mechanical installations. With customizable spans ranging from 96 to 120 meters, the system allows for completely unobstructed internal space without intermediate columns. This provides exceptional layout flexibility for forklift traffic, tall racking systems, automated warehouse machinery, and bulk storage operations that require full ground-level freedom.

Manufactured with high-strength Q235B or Q355B circular hollow steel sections, the structure achieves an optimal balance between light weight and high load-bearing capacity. The circular tube profile helps reduce stress concentration and improves bending and torsional resistance. All steel members are produced with advanced CNC precision fabrication to ensure consistent accuracy, superior joint integration, and long-term structural reliability during continuous industrial use.

A major advantage of this space frame system is the use of bolt-ball joints and conical connectors, recognized globally as one of the most efficient and reliable connection technologies for wide-span prefabricated steel structures. These connectors deliver excellent mechanical performance, fast onsite assembly, and simplified quality control. By minimizing welding work on the construction site, the system reduces installation risks, speeds up erection, and ensures high assembly accuracy even for very large spans.

To extend service life and protect the structure in demanding industrial or coastal environments, all steel components receive an epoxy zinc-rich primer, which provides excellent corrosion resistance and long-lasting adhesion. Optional coating upgrades include polyurethane finishing, anodized treatment, and other advanced surface protection systems depending on project location and environmental conditions. With proper maintenance, the space frame is engineered to provide a 50-year design lifespan.

The entire structure is optimized for module-based prefabrication, allowing most parts to be manufactured in a controlled factory environment. Each module is delivered to the jobsite ready for assembly, significantly shortening construction schedules. The system supports multiple installation methods including high-altitude assembly, block lifting, and the sliding installation method, which is particularly effective for long-span roofs and reduces the need for large cranes or extensive scaffolding. This results in lower onsite labor requirements, improved safety, and minimized downtime during installation.

Versatility is a core characteristic of this product. The structure can be fully customized to meet project-specific requirements such as overall length, module spacing, roof shape, color options, and environmental load considerations. The lightweight design supports different roofing materials including metal sheets, insulated sandwich panels, ETFE membrane, or skylight systems to improve energy efficiency and natural lighting inside the warehouse. The adaptable design also supports add-ons such as ventilation systems, solar panel installations, and HVAC equipment.

All engineering, fabrication, and quality processes comply with international standards including CE and ISO9001, as well as national building codes such as GB50583-2020, JGJ7-2010, and related construction specifications. The structure is engineered according to regional wind, snow, and climate requirements to ensure complete safety, stability, and long-term performance in a wide range of global project environments.

In summary, the Prefab Steel Warehouse Space Frame Structure offers a combination of large-span capability, lightweight prefabricated construction, superior structural performance, and excellent cost efficiency. It is an ideal solution for industrial clients seeking a durable and customizable warehouse roofing system that maximizes internal space, reduces installation time, and delivers long-term value. Whether used for logistics, storage, manufacturing, or bulk material operations, this space frame structure provides a dependable and high-quality building solution tailored to modern industrial standards.
