Sheet metal is one of the widely used material for construction of components across many industries. Every industry starting from automobile, construction, mining, shipping, manufacturing, aviation, medical, to transport has an application of sheet metal. Beyond the industrial use, sheet metal finds its application in domestic appliances too.
So, from the perspective of a mechanical design engineer sheet metal is a very important material to consider. There is no surprise if we come across increasing demand for sheet metal from various industry sectors as published in the market research reports.
The global sheet metal market size was valued at USD 265.0 billion in 2018. The global sheet metal market size is expected to reach USD 371.8 billion by 2025, progressing at a CAGR of 5.0% over the forecast period. Increasing demand for sheet metal from automotive sector is likely to contribute to the industry growth.
– According to GrandViewResearch.Inc
Simply put sheet metal is nothing but a metal in the form of sheets. In its raw material form the sheet metal is obtained by a rolling process. Here the height of a metal ingot is reduced by passing it through the rollers. This process makes the sheet uniform in thickness.
Sheet metal is identified by its thickness. The thickness is around 1 mm to around 20-25 mm. Sheet metal has thickness lesser than plate metal and it is thicker than a metal foil.
Applications of Sheet Metal
Sheet metal is eco-friendly and versatile raw material. One can see the sheet metal in the form of flat pieces or coiled strips. As sheet metal is easy to cut and bend, numerous industrial as well as domestic objects can be fabricated with it.
Following is the list of a few applications of sheet metal.
- Radiator supports, roof headers, frames, engine cradles in automotive sector
- Roofs and sidings in construction sector
- Ductwork, machine guards, tank bodies
- Airplane fuselages and wings
- Medical tables
Advantages of sheet metal
Sheet metal is good for manufacturing larger parts with less features. Let us look at what the advantages of this raw material are.
- Sheet metal has a low weight and hence it is easy to work with and transport.
- With the help of CAD/CAM and CNC technology, sheet metal component fabrication process can be very accurate and efficient.
- Sheet metal is extremely strong and durable. It can withstand extreme environments like agricultural set up or very high temperature like industrial ovens.
- With process like sand blasting or powder coating sheet metal becomes resistant to corrosion, sunlight and moisture making it a choice for various whether conditions.
- Sheet metal is easily malleable. It can be cut, bent, stretched or formed in any shape. With this unique property, highly customized designs can be created with it.
- Sheet metal parts can be easily inspected for any damage. The parts can be easily removed without disturbing the entire structure. The repairing is also relatively easy.
- Sheet metal offers low cost advantages due to its durability, light weight, ease of transport, malleability etc.
- Products manufactured using sheet metal requires lesser maintenance and can last longer without need of replacement.
