Large-span steel structures

Tailored for industries demanding space, load, and span efficiency:

​Engineered for Strength, Span, and Efficiency​

Specializing in lattice columns and truss beams, our steel structure solutions deliver unmatched performance for industrial workshops requiring large spans, heavy loads, and open floor plans.

Lattice Columns: 

High-load-bearing, lightweight, and corrosion-resistant, these open-web structures minimize self-weight while maximizing load distribution (up to 100-ton crane capacities). Ideal for reducing foundation costs and adapting to complex geological conditions.

Truss Beams: 

Modular, node-connected designs with superior spanning capabilities (20–60m+), enabling reduced beam height, increased workshop clearance, and optimized space utilization. Perfect for heavy machinery, overhead cranes, and large-equipment installation.

Proven Expertise in Large-Span, Heavy-Duty steel frames Designs​

With decades of experience, we’ve delivered iconic projects like Zibo Gymnasium (100m continuous span) and Shandong University Stadium (120m span). Our team masters codes (GB50017, GB50009) to customize optimal solutions for unique load/span requirements.

Precision Design & BIM Integration​

Equipped with Tekla Structures, CAD, and 3D3S, our in-house team optimizes node connections, eliminates collisions, and aligns design with production. BIM integration ensures seamless data flow from design to construction, reducing rework by 30%.

High-Precision Manufacturing & Welding Excellence​

Advanced CNC cutting, automated welding (AWS D1.1 compliant), and robotic assembly guarantee tight tolerances (±1mm) and weld integrity (100% UT/MT tested). Strict ISO 9001 quality control ensures every component meets global standards.

Large-Component Fabrication & Logistics Mastery​

We handle oversized parts (e.g., 30m+ truss beams, 20m lattice column limbs) with in-house ultra-long production lines and specialized packaging. Our logistics network ensures safe, on-time delivery—even for remote sites.

End-to-End Project Support​

From initial design to on-site installation guidance, we provide “design-manufacture-transport-install” full-service. Our technicians assist with crane alignment, node installation, and quality checks, ensuring projects stay on schedule.

ISO 9001 certified: Full-process control from raw material sourcing to final inspection.

100% dimensional/visual checks pre-shipment; certified test reports (MTRs) included.

Partner with third parties (SGS, BV) for independent validation of critical joints.
