Heavy-Duty Farm Welded Frames

Farm machinery frames must support heavy loads, resist impact, and withstand years of field use in dust, mud, and vibration. At Qingdao Tianhua Yihe Metal Fabrication (qdthyhmetalfab.com), we fabricate heavy-duty welded frames for agricultural equipment - including implement frames, toolbar frames, toolbar carriers, and equipment support structures. Our robotic welding cells ensure consistent, high-quality welds on volume production runs.

Manufacturing Capabilities

Frame fabrication begins with cutting RHS/SHS sections to length using band saw, followed by CNC drilling of mounting holes, welding in jigs for dimensional accuracy, and surface treatment. For volume production, we use robotic welding cells with multi-position fixtures. Each frame is checked for squareness and twist before coating.

Quality Assurance

Squareness and twist measurement on 100% of frames before coating

Jig-based dimensional control with first-article inspection reports per design

Mounting hole positions verified with fixture gauges

Material test certificates (MTC) provided with every shipment

ISO 9001:2015 certified quality management system

Frequently Asked Questions

Q: Can you fabricate frames from RHS and SHS sections?

A: Yes, we work with all standard RHS (rectangular hollow section) and SHS (square hollow section) sizes, from 50x50 to 300x300.

Q: Do you use welding jigs for frame production?

A: Yes, we build custom jigs for each frame design to ensure dimensional accuracy and repeatability across production runs.
