The term metal fabrication broadly encompasses the entire process of producing metal goods through various metalworking techniques, including cutting, bending, welding, and finishing. The importance of metal fabrication lies in its pivotal role within the commercial and industrial manufacturing sectors, where it enables the creation of custom and standardized metal products for construction, automotive, aerospace, electronics, and many other applications. Whether you are searching for custom metal fabrication, contract manufacturing, or specialized sheet metal fabrication services, understanding the nuances of this field can help ensure you partner with the right metal fabrication company for your project.

What is Metal Fabrication?

Metal fabrication involves transforming raw metal materials into finished, usable products through a series of processes such as cutting, shaping, bending, assembling, and surface finishing. These processes may be manual, automated, or a combination of both, depending on production requirements and precision needs.

Typically, metal fabrication shops are centralized facilities equipped with a variety of metalworking tools and technologies, enabling them to handle complex fabrication projects from start to finish. These shops employ skilled specialists in different areas of metallurgy, such as certified welders, blacksmiths, CNC machine operators, and sheet metal technicians. Common metalworking processes within a metal fabrication project include casting, bending, stamping, welding, punching, CNC machining, shearing, rolling, and forging. It’s important to note that while metal fabrication and welding are closely related, welding is just one phase within the broader metal fabrication workflow.

Common Materials Used in Metal Fabrication

Nearly any metal or metal alloy can be utilized to create a product or part of a product, but certain materials are more commonly chosen than others. Steel, stainless steel, and aluminum are the primary materials used in metal fabrication. Other frequently used metals include bronze, brass, copper, and titanium, each offering unique properties that make them suitable for specific applications. For instance, stainless steel is favored for its corrosion resistance and shiny appearance, making it ideal for food processing equipment, medical devices, and decorative architectural features. Galvanized steel (steel coated with zinc) is a cost-effective option for outdoor structures due to its rust-resistant properties. Similarly, copper is prized for its electrical conductivity and visual appeal, while aluminum is chosen for its lightweight, high strength-to-weight ratio, and natural resistance to corrosion.

Fabricated metal products are rarely made from freshly mined, unprocessed metals. Instead, they are typically fabricated from pre-processed or semi-finished metal materials. The standard raw materials used by metal fabricators include sheet metal (referred to as plate metal when its thickness reaches a quarter-inch), tube stock, bar stock, welding wire or welding rod, formed and expanded metal, metal castings, and a variety of metal fittings. Each raw material form offers distinct advantages for different fabrication methods. For example, CNC machining is often performed on solid bar or tube stock for high-precision parts, while sheet metal fabrication is favored for creating enclosures, panels, and brackets due to its versatility and ease of forming.

Main Stages of Metal Fabrication

To create various products from different types of raw materials, metal fabricators rely on a wide range of processes. The primary methods of metalworking are detailed below. While it may be an oversimplification, most metal fabrication projects can be categorized into four main stages: cutting, shaping (often involving bending and forming), assembling or joining (primarily through welding), and finishing.

1. Cutting

Cutting is the initial step that transforms raw metal into a workable size or shape. This may be done manually with hand tools or with advanced, automated equipment such as CNC laser cutters, plasma cutters, or waterjet machines. CNC (Computer Numerical Control) machinery is especially valued for its precision and ability to handle complex geometries in both high-volume and custom fabrication projects. When working with sheet or sectional metal, cutting typically involves shear cutting operations like shearing (removing large parts of the stock with a shearing blade), punching (creating holes in the stock with a punch mechanism), and blanking (removing the perimeter from the stock). Non-shear operations, such as laser cutting, waterjet cutting, and plasma cutting, offer higher precision and cleaner edges, making them ideal for intricate work and tight tolerances.

2. Shaping and Forming

The intermediate step of metal fabrication, often termed shaping or metal forming, involves transforming metal and metal components into a desired shape after they have been properly cut. This is usually achieved with dies and presses, which hold the raw material in place as it is worked. Stamping presses, for example, use dies and punches to form coiled or blank sheet metal into a net shape. Common shaping and forming processes include:

• Embossing – Stretching the material into a hollow depression for decorative or functional purposes.
• Flanging – Bending the material along a curved line to add strength or allow for assembly.
• Coining – Compressing or imprinting a pattern into the material for surface texture or identification.
• Bending – Deforming the material along a straight line, often with press brakes or manual tools.

Some projects may require roll forming, a continuous, high-volume process where metal strips are passed through a series of rollers to create products like channels, trim, and rails. Press braking is better suited for smaller production runs or custom shapes, using a press brake machine to force metal into a shaped indentation for precise bends.

3. Assembling or Joining

Assembling or joining is a crucial stage in the metal fabrication process, where multiple metal parts are fused or fastened together to create a finished product or sub-assembly. Before assembly, metal pieces are held in place with clamps and fixtures to ensure accuracy. Assembly techniques include mechanical fastening (using adhesives, threaded fasteners, or riveting), brazing, and, most commonly, welding. Welding forms the strongest bonds between metal parts and is essential for structural steel fabrication, industrial equipment, automotive components, and more.

Welding processes can derive heat from various sources, including friction, ultrasound, gas flames, electron beams, electric arcs, and lasers. Common welding methods include:

• Shielded metal arc welding (SMAW)
• Flux-cored arc welding (FCAW)
• Submerged arc welding (SAW)
• Electroslag welding (ESW)
• Electric resistance welding (ERW)
• Oxyacetylene welding (OAW)
• Gas metal arc welding (GMAW) – including metal inert gas (MIG) welding and metal active gas (MAG) welding
• Gas tungsten arc welding (GTAW) or tungsten inert gas (TIG) welding – highly valued for its precision and clean welds

Welding is so versatile and critical that advanced processes have been developed for unique applications, such as underwater welding for marine structures and aerospace welding for spacecraft and satellites. Beyond these specialized fields, welding remains a cornerstone of industrial manufacturing, automotive fabrication, energy production, and infrastructure construction.

4. Finishing

The finishing stage of metal fabrication involves enhancing the surface properties of metal products, either to fortify them against environmental damage or to improve their aesthetic appeal. Common finishing techniques include:

• Cleaning and degreasing with organic solvents (like acetone) or alkaline solutions
• Painting or powder coating for improved corrosion resistance and color customization
• Anodizing (especially for aluminum) to create a protective oxide layer
• Electroplating to deposit a metal layer (such as chrome or nickel) for enhanced wear resistance or conductivity
• Polishing, brushing, or sandblasting for desired surface textures or finishes

Finishing processes are often tailored to the end-use environment of the product, whether that means protecting against weather, chemicals, or abrasion, or simply meeting strict cosmetic requirements for consumer goods.

For every metalworking request, metal fabricators have a method to fulfill it. Through cutting, burning, forming, machining, welding, and related fabrication services, metal fabrication shops can provide customers with a wide variety of standard and custom fabricated parts. If you need rapid prototyping, small-batch manufacturing, or full-scale production, a qualified metal fabrication company can help you achieve your project goals.
