Working in construction or industrial manufacturing, you have most
likely already come across a variety of metal options in varying
lengths and sizes. But what about metal thicknesses? What is the
difference between sheet, plate, and foil?
When choosing
between the three types of products, the only difference is the thickness:
- Metal plate is classified with the
thickest options
- Metal plate reflects sheet metal
6mm or thicker
- Metal
sheet with medium thickness
- Metal sheet
reflects any metal from 0.5mm up to 6mm
-
Metal foil with the thinnest options
- Metal foil is categorized by sheet metal with a thickness
less than 0.2mm
US-based metal suppliers commonly measure the differences between
metal sheet, plate, and foil in millimeters. British metal
manufacturers and engineers will often use mils. The use of gauges,
while sometimes still used, is discouraged. Gauge numbers can vary,
having limited usefulness without having general agreement on meaning.
Metal Sheet, Plate, and Foil Variables
Aluminum, steel, stainless steel, copper and brass, are common
non-ferrous metals available in metal sheet, plate, and foil options.
Your project requirements will determine which alloy is best suited,
while differentiation of each sheet metal option can help decide which
thickness will work best for you.
Plate Metal Applications
- Stainless steel plate is often used for industrial
applications like construction or applications that require its
hygienic properties such as food processing applications.
- Steel plate is ideal for a broad range of applications such a
structural support or heavy machinery manufacturing.
- Aluminum plate can be used in aerospace and automotive
manufacturing where its mechanical properties can withstand wide
temperature ranges.
Sheet Metal Applications
- Stainless steel sheet is used for both industrial and
commercial applications. Its corrosion resistance makes it well
suited for fasteners, machinery components, heat exchanges, and food
service parts.
- Steel sheet is well suited
for railings, gates, and automotive components.
- Aluminum
sheet can be found in commercial applications like packaging as well
as home appliances, building and construction, and automotive body
panels.
- Brass and copper sheet is useful for decorative
components as well as mechanical applications.
Foil Metal Applications
- Stainless steel foil is used for a wide range of
industries including foodservice, packaging, construction, and
chemical processing. It is often used as a wrap or for
enclosures or covers.
- Steel metal foil is commonly used
for shielding or fabrication applications.
- Aluminum
foil sheet is often used for tooling or decorative designs.
- Copper and brass foil can be used for decorative
purposes/hardware.
Why Different Sheet Metal Thicknesses Matter for Metal Fabrication
Understanding the differences between metal thicknesses can
ensure you choose the best metal option for your project
requirements. Each alloy’s mechanical and physical properties can
also factor into your metal decision.
