What is Custom Metal Fabrication?

Custom fabrication forms desired shapes and products from raw metal materials. Several processes are used to fabrication metal into products. Working with a variety of steel, our team of skilled metal fabricators can produce everything from ductwork to capture hoods to thermal oxidizers and everything in between. Whether you have a spec or need help from our engineering team, we are ready to help you complete your fabrication project.

Custom Metal Fabrication Process

The process of custom metal fabrication varies depending on the needs of each project. However, it typically involves a few main techniques: cutting, forming, welding, and assembly.

  • ASME Certified Welding

    Welding fuses parts together through heating, and the connection forms as the part cools. There are multiple types of welding available, including:

    • MIG
    • TIG
    • Flux Core
    • Stick

    AGI is ASME-certified for structural steel and stainless steel, carbon steel and coated sheet metal, stainless sheet metal, and specialty alloy sheet metal.

  • Cutting

    Metal cutting involves a number of complex processes that vary based on the type of metal used. The desired final product also plays a role in cutting method selection. The most common cutting processes include:

    • Laser Cutting
    • Punching
    • Mechanical Cutting
    • Shearing
    • Waterjet Cutting
  • Forming

    Forming is the process of bending metal into the desired shape. There are several forming methods, including roll forming, air bending, and coining.

  • Joining/Assembly

    The joining process is when the completed metal components are assembled together to create the finished product. This process can involve riveting, installing hardware fasteners, or welding. Our welding services include MIG, TIG, stick, flux core, spot welding, and laser welding.

Types of Custom Metal Fabrication

AGI offers several types of custom metal fabrication services, including ductwork, pipe, equipment, and structural fabrication.

Equipment Fabrication

AGI Fabricators supports the needs of industrial and commercial businesses that lack the infrastructure needed for large-scale equipment fabrication projects. Our team consists of certified welders and weld inspectors, electricians, structural and mechanical engineers, insulators, and painters to ensure your project is completed according to your specifications and industry standards. We work with a number of tools and design software programs, including 3D printing, AutoCAD, SolidWorks, and Revit.

Ductwork Fabrication

Ductwork fabrication creates the essential framework for various systems. It is commonly used in HVAC systems to supply and remove air, but we also have experience in industrial systems for dust collection and process ventilation. The connected network ductwork within a system carries cool or warm air throughout a building. It also ensures comfortable indoor temperature control, sanitary air quality, and energy efficiency. At AGI Fabricators, our custom metal ductwork fabrication services are expertly handled to ensure no temperature degradation or air loss.

Pipe Fabrication

Virtually every type of modern infrastructure depends on piping systems for transporting gas, liquids, and solid substances. Pipe fabrication involves creating both the straight carbon and stainless steel pipes as well as the piping components these systems require. AGI Fabricators supports piping system reconfiguration, emergency repair, and maintenance by producing the pipes, flanges, tees, reducers, elbows, and other components piping systems require. Our pipe fabrication services involve cutting, beveling, and welding processes to create accurate parts that adhere to all required standards.

Structural Fabrication

AGI Fabricators’ structural fabrication team includes highly experienced project managers, structural engineers, and certified catalog and field welders. We also have an in-house certified weld inspector to ensure each weld adheres with your industry’s unique requirements and safety standards.

Our team works with AutoCAD, Revit, and SolidWorks to meet the needs of numerous industries, including pharmaceutical, material handling, food processing, pollution control, and many others. When you partner with us, you can expect a fast proposal turnaround, short project commencement lead time, and 100% satisfaction with every structural fabrication project.

Applications of Custom Metal Fabrication

Custom metal fabrication creates a large number of highly diverse products. At AGI Fabricators, we’re experienced in meeting the needs of industry-diverse applications.

Construction Parts

Custom metal fabrication is suitable for producing durable, strong, and long-lasting parts and components for the construction industry. The process can be used to fabricate everything from window and door frames to structural framing, reinforcing bars, truss systems, and much more.

Construction Parts

Process Skids

A skidded process system is a method for implementing a new process into an existing facility. In a skid system, a manufacturer constructs equipment, tests, and validates it before shipping it to its final destination where it will be installed. Modular process skids offer many benefits, including reduced installation downtime, faster start-up, and easy scalability as process requirements change.

Environmental Control Products

At AGI, we have manufactured various environmental control solutions, including thermal oxidizers, scrubbers, and other energy generation products. Environmental control products are critical for industrial facilities and their ventilation systems to keep safe working environments. Our large manufacturing facility in Milwaukee, Wisconsin allows for the fabrication of these products. We are familiar with environmental control products and have engaged with fabrication, testing, and delivery for select customers.
