Metal Fabrication

We ensure a high standard of quality control with our in-house fabrication of industrial ventilation systems, material handling constructs, structural steel solutions and machine guarding. Our dedicated quality control lead checks each piece prior to shipment and on-site assembly, reducing installation costs by ensuring the right fit.

Our Goal: The right fit the first time!

Metal Fabrication Capabilities

Our metal fabricators and fabrication facilities work with a variety of metal substrates including:

  • Stainless steel
  • Aluminum
  • Galvanized steel
  • Hot and cold rolled mild steel
  • COR-TEN®
  • Structural steel

Spiral Duct Fabrication

IVI’s skilled craftsmen, using state-of-the-art equipment, fabricate spiral ducts with a material thickness of 26 to 16 gauge for galvanized steel and up to 18 gauge maximum for stainless steel. Rolling diameters of spiral duct range from three to 10 inches at one-inch increments or from 12 to 48 inches at two-inch increments.

IVI stocks a variety of spiral tubing, including from four- to 14-inch diameter, 20-gauge galvanized spiral in 10-foot lengths.

Quality Assurance

Our quality assurance program starts with the quality of our people.

We rely on the integrity and performance of our highly skilled and experienced engineers, draftsmen, journeymen and quality control personnel. The head of our quality control program has more than 20 years of experience. Our certified journeymen receive annual training in safe practices and proper procedures. The entire IVI team considers quality control an intricate part of their everyday job.

We want our product to be reliable, safe, strong and maintainable.

All prints are checked by our engineering and design teams before going to the production floor. Once there, all items undergo a three-point inspection process for dimension, size, location or placement, material and workmanship before leaving our facility. These procedures guarantee that the finished product will meet or exceed industry standards and satisfy all OSHA requirements.
