No matter the application and requirement of your sheet metal parts, you’ll find the right material when you trust RapidDirect. The following outlines some popular materials available for custom metal fabrication.
Commercially, aluminum is the most sought-after material for sheet metal manufacturing. Its popularity is due to its adaptive qualities and its high thermal conductivity and low resistance rates. Compared to steel—another common sheet metal material—aluminum is more cost-effective and has a higher rate of production. The material also generates the least amount of waste and can easily be reused.

Whether it’s metallic auto parts or electronic device components, RapidDirect’s sheet metal fabrication has helped businesses in different industries.
Sheet metal fabrication involves cutting, shaping, and joining metal sheets into various components. It transforms flat metal sheets, like steel or aluminum, into designed structures using specialized techniques and tools, catering to diverse applications.
The process starts with CAD-designed blueprints. Next, the metal is cut using techniques like laser cutting. It’s then bent into shapes using machinery. Components are assembled through welding or riveting, followed by finishing processes for appearance and protection, ensuring product quality.
Predominant materials in sheet metal fabrication include stainless steel (for its strength), aluminum (lightweight, corrosion-resistant), brass (decorative fixtures), copper (electrical components), mild steel (versatile), and galvanized steel (corrosion-resistant due to zinc coating).
Sheet metal fabrication serves various industries: automotive (vehicle parts), aerospace (aircraft parts), construction (components like HVAC ductwork), electronics (enclosures), and more. Its versatility allows production of everyday to specialized items.
RapidDirect offers a comprehensive range of services including cutting, bending, punching, welding, and assembling. Our state-of-the-art machinery ensures precision and high-quality finishes for all projects.
Sheet metal fabrication tolerances refer to the acceptable deviations for features of sheet metal parts required for accurate and consistent installation and integration.
For sheet metal parts, ISO 2768-mk is usually used to ensure proper control of the elements of geometry and size. The following will show you 7 tolerance standards range of linear and angular dimensions, flatness & straightness, cylindricity, and circularity.
K factor is the sheet metal process is the ratio of neutral axis to material thickness. This value changes with respect to the various physical properties and thickness of materials used.
Every aspect of a sheet metal fabrication project comes with an associated cost — the design, possible prototype, finishing processes, and others. Asides from the process itself, materials also cost money. To learn some tips for reducing custom sheet metal fabrication costs, you can learn from this article.
