Our 75,000 m² production facility processes 80,000 tons annually with ±0.1mm CNC drilling precision, ensuring every column meets EN 1090 and AWS D1.1 international standards.
You'll appreciate the efficiency: our Tie Plates Lattice Column design reduces installation time by 51% compared to traditional concrete solutions, directly impacting your project timeline and labor costs.
Product Advantages
Superior Structural Efficiency
Your engineering challenges require smart material usage. Our lattice design maximizes the radius of gyration relative to cross-sectional area, giving you higher stiffness-to-weight ratios than solid-web alternatives. This means you're using less steel to achieve the same—or better—structural performance.
Accelerated Project Delivery
Time is money on your construction site. The prefabricated nature of our columns means faster on-site assembly. You can bolt segments together in space-constrained environments without heavy lifting equipment or extensive scaffolding.
Cost Optimization
We understand budget pressures. Our system reduces material costs while maintaining structural integrity. The open lattice configuration also minimizes wind resistance—critical for tall structures—reducing foundation requirements and overall structural loads.
Enhanced Durability
Your structures face harsh conditions. Our hot-dip galvanizing process (minimum 85 microns) ensures superior corrosion resistance. The open lattice design allows easy inspection and maintenance access, extending service life and reducing lifecycle costs.
Design Flexibility
Every project is unique. Our 3-axis CNC systems and 1200-ton plate rolling machines enable complex custom configurations. Whether you need specific connection details, non-standard heights, or special anti-corrosion treatments, we adapt to your requirements.
Seismic Resilience
Safety can't be compromised. Our columns come with seismic design verification reports, demonstrating proven energy dissipation and redundancy in earthquake-prone zones—protecting your investment and occupants.

Manufacturing & Quality Control
Advanced Production Infrastructure
You're partnering with a facility that means business. Our 120,000 m² campus houses cutting-edge equipment including 50-ton crane capacity workshops, automated welding lines, and CNC cutting systems that handle ultra-thick plates up to 300mm. This isn't just capability—it's your assurance of precision and consistency.
Multi-Layer Quality Verification
Material Traceability: Every batch comes with full Mill Test Certificates (MTC) documenting chemical composition and mechanical properties. You'll know exactly what you're getting.
Welding Integrity Testing: We employ Ultrasonic Testing (UT) and Magnetic Particle Inspection (MPI) on all critical welds between tie plates and angle members. This eliminates cold joints, porosity, and hidden defects before they reach your site.
Dimensional Precision: Our three-axis CNC drilling systems maintain ±0.1mm accuracy. We verify column straightness (L/1000 tolerance), tie plate positioning, and overall geometry using laser measurement systems.
Coating Quality Assurance: For galvanized products, we conduct PosiTector gauge testing and adhesion hammer tests per ASTM A123 and ISO 1461 standards. You're getting corrosion protection that lasts decades, not years.
International Certification Framework
Our ISO 9001, ISO 14001, and ISO 45001 certified management systems ensure consistent quality across every order. We maintain compliance with EN 1090 (EU), AWS D1.1 (USA), and JIS (Japan) standards, providing the documentation you need for international projects.

FAQ
Q: Why choose tie plates over continuous lacing bars for my column design?
A: Tie plates simplify fabrication and provide robust shear resistance at specific intervals, making them ideal for medium-height applications. They're also easier to inspect and maintain. For very high slenderness ratios, we can recommend lacing alternatives based on your specific load conditions.
Q: How do you calculate the effective length for buckling analysis?
A: We account for the slenderness of individual angle segments between tie plates to ensure local buckling doesn't occur before the column reaches its global design load. Our engineering team provides full calculations per AISC 360 or Eurocode 3 requirements.
Q: What's the recommended tie plate spacing for my application?
A: According to design codes, the slenderness ratio of a single angle between plates shouldn't exceed 75% of the entire column's governing slenderness ratio. We optimize this spacing based on your specific load conditions and height requirements.
Q: Can these columns perform in seismic zones?
A: Absolutely. Our columns provide excellent energy dissipation and structural redundancy when connections are designed for ductility. We provide seismic design verification reports for earthquake-prone regions.
Q: How do you manage corrosion at the plate-angle interface?
A: Our hot-dip galvanizing process ensures complete coverage, including overlap zones. For critical applications, we offer additional sealing treatments and inspection protocols.
Q: What's your typical lead time for custom configurations?
A: Standard configurations ship within 20 working days. Custom designs with special anti-corrosion treatments require 25 days. We offer expedited 15-day production for urgent projects.
Q: Do you provide installation support?
A: Yes. Our services include installation guidance, on-site technical support, and full documentation packages with English technical drawings for international projects.
