Industrial Steel Truss Building Q355B Welded Roof Truss Frame Structure

Product Specification

Product Description

Our Industrial Steel Truss Building is engineered with a robust Q355B welded roof truss frame system, delivering exceptional structural efficiency for large-span industrial applications. The truss-based design provides superior load distribution, allowing for wider column-free interiors compared to conventional portal frames. Ideal for factory workshops, manufacturing plants, and heavy industrial facilities requiring crane integration and open floor layouts.

Each truss assembly is factory-welded under precision jigs and inspected to stringent quality standards. The modular truss sections are bolted together on-site, drastically reducing construction time while maintaining the highest structural integrity. With a service life exceeding 50 years and minimal maintenance requirements, this steel truss building is the cost-effective choice for long-term industrial infrastructure.

Key Features

• Q355B Welded Roof Truss System: Pre-engineered triangular or trapezoidal truss frames fabricated from Q355B (S355JR) high-strength structural steel, optimized for maximum span-to-weight ratio.
• Wide Column-Free Spans: Truss design enables spans up to 80 meters without intermediate columns, maximizing usable floor area for production lines and crane operations.
• Integrated Crane Runway Support: Truss columns can be designed with built-in crane runway beam brackets for overhead cranes up to 30 tons capacity.
• Factory Precision Welding: All truss members are cut, coped, and welded in a controlled factory environment, ensuring consistent quality and rapid on-site bolted assembly.
• Customizable Roof Profile: Single-slope, double-slope, or multi-gable roof configurations available to match architectural and functional requirements.
• Advanced Corrosion Protection: Shot blasted to SA 2.5 finish with epoxy zinc-rich primer and polyurethane topcoat, or full hot-dip galvanization for corrosive environments.
• Ventilation & Lighting: Ridge ventilators, FRP skylight panels, and louver systems can be seamlessly integrated into the truss roof design.

Customization & Engineering Support

KXD Steel Structure provides complete engineering support from concept to completion. Our in-house design team uses Tekla Structures, SAP2000, and AutoCAD for 3D modeling and structural analysis. We design to international codes including AISC, EN 1993 (Eurocode 3), GB 50017, and BS 5950. Detailed shop drawings, erection manuals, and on-site supervision are available. Third-party inspection by SGS, BV, or TUV is welcomed.

Packing & Shipping

Truss sections are nested and secured on steel pallets for 40ft open-top containers. Columns and beams are bundled with steel strapping. Purlins, bracing, and accessories are packed in labeled crates. Roof and wall panels are protected with plastic film and loaded in 40ft high-cube containers.

FAQ

Q: What is the advantage of a truss building over a portal frame?
A: Truss buildings achieve significantly wider spans (up to 80m) and can support heavier crane loads while using less steel per square meter compared to conventional portal frames.

Q: Are you a manufacturer?
A: Yes, we operate 3 workshops in Qingdao, China, with complete steel structure fabrication, welding, and surface treatment capabilities. ISO 9001 and CE certified.

Q: Can you design for our local conditions?
A: Absolutely. Our engineering team designs for your specific wind loads, snow loads, seismic zone, and local building codes.

Q: Do you provide installation?
A: We provide detailed installation drawings and can supply an on-site supervisor or complete turnkey installation team as required.
