Welded Structural Assemblies

Beyond standard beams and columns, structural steel projects often require custom welded assemblies - connection brackets, gusset plates, support frames, lifting lugs, and other fabricated components that don't fit standard catalog categories. At Qingdao Tianhua Yihe Metal Fabrication (qdthyhmetalfab.com), we manufacture custom welded structural assemblies from your drawings, bringing together our cutting, bending, and welding capabilities to produce exactly what your project requires.

Manufacturing Capabilities

Our flexible fabrication cell handles custom structural assemblies of all types. Laser cutting provides precise plate components, CNC press brake forms bends and angles, and our welding cells (both manual and robotic) handle MIG, TIG, and SAW processes. We fabricate everything from simple brackets to complex multi-piece assemblies with stiffeners, gussets, and connection plates.

Quality Assurance

Full-penetration weld control on safety-critical components (lifting lugs) with NDT reports on request

Fit-up verification of multi-piece assemblies before final welding

Dimensional sign-off on critical connection points for every assembly

Material test certificates (MTC) provided with every shipment

ISO 9001:2015 certified quality management system

Frequently Asked Questions

Q: What is the maximum assembly size you can fabricate?

A: Maximum dimensions are approximately 12m x 3m x 2m, limited by transport. For larger assemblies, we can fabricate in sub-assemblies for site welding.

Q: Can you weld lifting lugs and other critical components?

A: Yes, we weld lifting lugs and other safety-critical components with full-penetration welds and provide weld testing certificates where required.

Q: Do you provide material test certificates?

A: Yes, all material comes with mill test certificates (MTC). We provide MTCs with every shipment.
