Steel Columns & Base Plates

Steel columns and base plates form the critical load-transfer interface between structural steelwork and concrete foundations. At Qingdao Tianhua Yihe Metal Fabrication (qdthyhmetalfab.com), we fabricate custom steel columns - from standard UC sections with welded base plates to complex built-up box columns with stiffeners and cap plates. Every column is manufactured to your structural drawings, with precise hole positions for anchor bolts, full-penetration welds at base plate connections, and surface treatment suited to your environment.

Manufacturing Capabilities

Columns are fabricated using our full structural steel process: plate cutting, section welding, base plate welding with full-penetration bevel welds where required, stiffener welding, CNC drilling of base plate holes, straightening, and surface treatment. We maintain strict dimensional control on column squareness and base plate flatness to ensure proper seating on anchor bolts.

Quality Assurance

Base plate flatness verified with straightedge gauges before coating (critical for anchor bolt seating)

Anchor bolt hole positions checked to ±0.5mm against template plates

Full-penetration weld control at base plate connections with NDT available on request

Material test certificates (MTC) provided with every shipment

ISO 9001:2015 certified quality management system

Frequently Asked Questions

Q: Can you fabricate columns with stiffener plates?

A: Yes, we weld stiffener plates inside box columns and at base plate connections per your structural drawings. Stiffener spacing and welding are controlled by design requirements.

Q: What base plate sizes can you accommodate?

A: We fabricate base plates from 200mm to 800mm square, in thicknesses from 12mm to 50mm. Custom shapes (rectangular, circular) are also available.

Q: Do you provide cap plates for columns?

A: Yes, we weld cap plates with pre-drilled holes for beam-to-column connections. Cap plate design follows your connection details.
