Engineer Vast, Column-Free Spaces with Our Advanced Steel Space Frame Truss
Welcome to the future of structural engineering. Our ProX Series Steel Space Frame Truss is the premier solution for architects and engineers designing large-span facilities. Whether you're constructing an airport, a sports arena, an industrial warehouse, or a commercial complex, our space frame truss system provides the unmatched strength, flexibility, and durability you demand. Forget limitations and imagine the possibilities of wide-open, unobstructed space.
Why Our Space Frame System is the Smartest Structural Choice
A superior steel truss structure is defined by its engineering, materials, and execution. Our system is meticulously designed to excel in all three areas, delivering a roof structure that is as reliable as it is impressive.
Unbeatable Strength & Durability: Fabricated from high-grade Q235B/Q345B steel, our space frame roof components are built to last. The robust circular hollow sections and precision bolt-ball joints create a monolithic structure capable of supporting heavy roof loads, significant snow accumulation, and high-wind events, ensuring your asset is protected for decades.
Maximum Design Flexibility: Your vision shouldn't be constrained by structural limitations. Our steel space frame design is highly customizable in span, height, and grid pattern. This adaptability allows us to create tailor-made solutions that fit your exact architectural and functional requirements, enabling unique and complex geometries.
Cost-Effective & Rapid Construction: Time is money. Our system is prefabricated off-site with pinpoint accuracy. This means faster, safer assembly on your site using methods like the efficient sliding technique for long spans. You benefit from reduced labor costs, shorter project timelines, and minimal on-site disruption
Key Features That Set Our System Apart
Pre-Engineered for Performance: Every connection and member is optimized using advanced modeling to ensure maximum efficiency and safety under all design loads.
Long-Term Corrosion Defense: The standard epoxy zinc-rich primer coating provides a formidable barrier against rust and corrosion, safeguarding the structural integrity and minimizing maintenance over its 50-year service life.
Proven Compliance & Quality: Our systems are designed in strict accordance with major international standards, including GB50583-2020 and JGJ7-2010, and are backed by CE and ISO9001 certifications, guaranteeing a product of the highest quality and reliability.
