Skeleton of Strength

Structural Steel Frame

The backbone of every Champion building is a precision-engineered steel truss system, designed for maximum clear-span width and extreme load resistance.

Truss vs. Solid Frame

Engineered for Efficiency

Unlike conventional solid-web I-beams, Champion utilizes open-lattice steel trusses. This design offers a superior strength-to-weight ratio, allowing for massive clear spans up to 80 m without interior columns.

Our truss systems are optimized to resist lateral wind loads and heavy snow accumulation while providing an open, airy interior environment for industrial operations.

⚙

Design Features

Why Champion Frames?

Our engineering team focuses on three core pillars: Durability, Scalability, and Ease of Assembly.

🗻

Lattice Truss

Triangulated web members provide exceptional rigidity and minimize deflection under heavy snow loads.

⎵

Portal Frame

Rigid-jointed frames maximize vertical clearance at the sidewalls for equipment movement and shelving.

🏗

Hanging Load

Trusses can be engineered to support conveyors, lighting, and HVAC equipment up to specific capacities.

Comparison

Truss vs. Conventional Steel

Understanding the structural advantages of our tension fabric building skeletons.

▲ Truss Advantages

Lower foundation requirements due to lighter dead weight
Easy to transport and assemble in remote or sensitive locations
Massive clear spans without center supports for flexible layouts
Natural airflow through the open truss design reduces condensation
Lower lifecycle cost due to 50+ year galvanizing life

▼ Conventional Steel Comparison

Solid beams are significantly heavier and more expensive to ship
Longer installation times requiring heavier crane capacity
Lower resistance to coastal salt-air corrosion unless specialty coated
Interior columns often required for spans over 30 m

FAQ

Steel Frame FAQ

With hot-dip galvanizing, our steel frames are designed for a service life of 50+ years even in demanding environments like salt storage or coastal sites.

Yes. The modular nature of our truss system allows for additional bays to be added to increase the building's length at any time.

Absolutely. We use certified structural steel from Tier-1 mills with full traceability and mill test reports (MTRs) provided with every project.

No. Hot-dip galvanized steel is self-healing and requires virtually zero maintenance compared to painted steel which needs regular repainting.

All welding is performed by certified technicians according to AWS D1.1 or equivalent international standards for structural steel welding.

Advanced Metallurgy

Steel Material Specifications

The structural integrity of a Champion building starts with the selection of premium-grade steel. We utilize heavy-duty structural sections and tubes sourced from certified mills, ensuring every member meets or exceeds the required yield strength for the project's specific wind and snow loads.

Our engineering team selects grades based on regional standards and availability, maintaining high weldability and ductility for long-term performance.

Standard	Grade	Yield Strength	Use
China GB/T	Q235B	235 MPa	Secondary purlins, bracings
China GB/T	Q355B	355 MPa	Primary truss chords & webs
ASTM (USA)	A36	250 MPa	Standard structural shapes
ASTM (USA)	A572 Gr.50	345 MPa	Heavy-duty structural load
EN (Europe)	S235JR	235 MPa	General structural use
EN (Europe)	S355JR	355 MPa	Critical structural members
