Custom Heavy-Duty Welded Frame & Industrial Machine Base

We specialize in precision structural steel fabrication and heavy weldments built to withstand demanding industrial environments. From single prototype frames to recurring batch production, our advanced cutting, welding, and post-machining facilities deliver rigid, distortion-free structural assemblies tailored to your engineering blueprints.

Key Manufacturing Capabilities

Precision Cutting & Preparation: High-definition laser, plasma, and precision band-saw cutting for structural tubing, beams, and thick steel plates.
Certified Welding & Stress Relief: Multi-pass MIG/MAG/TIG welding with strict heat-input control. Thermal stress-relieving (annealing) available to eliminate internal residual stresses prior to final machining.
Post-Weld Machining: Large gantry CNC milling and line-boring capabilities to machine critical mounting pads, datum faces, and guide rail interfaces after welding.
Surface Preparation & Finishing: Complete in-house shot blasting (SA 2.5) followed by durable industrial paint systems, powder coating, or hot-dip galvanizing.
