Heavy structural and plate metal fabrication — cutting, forming, machining, welding, and assembly of carbon steel, stainless steel, and specialty alloys, built to code from prototypes through full production runs.
Metal fabrication is the process of transforming raw structural steel, plate, and bar stock into finished components and assemblies — skids, structural frames, trusses, handrails, platforms, conveying systems, and heavy equipment structures — through a sequence of cutting, forming, machining, welding, and finishing operations. Where vessel and heat exchanger fabrication is built around pressure-retaining code compliance, metal fabrication covers the structural and non-pressure scope that supports and surrounds that equipment: the frames it sits on, the platforms it's accessed from, and the enclosures and trusses that tie a facility together.
Fintelius runs metal fabrication as a fully integrated discipline within our fabrication shops — sharing the same engineering, quality control, and welding qualifications used across our vessel and heat exchanger lines, so structural scope and pressure-equipment scope are delivered under one accountable team rather than split across vendors.
Six core operations carry a component from raw structural material to a finished, code-compliant assembly ready for shipment or site erection.
Plasma, laser, and waterjet cutting shape plate and structural sections to precise profiles while maximizing material utilization.
Hydraulic presses, press brakes, and rolling machines bend and roll plate into curved shells, angles, and complex profiles.
CNC machining produces components requiring tight dimensional tolerances — flanges, shafts, gears, and precision-fit parts.
Qualified welders using MIG, TIG, submerged arc, and shielded metal arc processes join components into stable, load-rated structures.
Fabricated components are fitted, aligned, and joined into completed structures, skids, or equipment packages.
Surface preparation, coating, dimensional inspection, and NDE confirm every assembly meets drawing and code requirements before shipment.
Metal fabrication spans a wide range of structural and mechanical scope — each type built to the same shop-controlled quality standard.
