Fundamentals of Sheet Metal

Sheet metal is metal formed into thin, flat pieces, typically through an industrial rolling process. It's a versatile material foundational to numerous industries, from automotive to consumer electronics.

What is Sheet Metal?

Sheet metal refers to flat, uniform metal sheets with consistent thickness, measured in gauge (a higher gauge indicates a thinner sheet). These sheets are easily formed, cut, bent, and joined to create complex designs and customized components.

Thin, Malleable, Versatile Metal

Key Properties & Advantages

  • Malleability & Ductility: Can be easily shaped without breaking.
  • Strength-to-Weight Ratio: Offers good structural integrity for its weight.
  • Corrosion Resistance: Many types are inherently resistant or can be coated.
  • Cost-Effective: High availability and efficient manufacturing processes.
  • Recyclability: Environmentally friendly due to high recyclability.

From precision parts to large enclosures, sheet metal is a cornerstone of modern manufacturing.
