What are the different types of sheet metal?

Designers and engineers who need a “red” metal usually choose electrolytically rigid pitch copper (ETP), C110 or C101. In less frequent cases, cassette brass is used as an alternative.

Prepainted steel

This sheet metal material is either hot-dip galvanized steel or galvannealed steel, which is galvanized and then annealed.

Stainless steel

Stainless steel base and spring are two classes used in sheet metal production.

Standard stainless steel can be non-magnetic; any of the 300 series steels are the most commonly used type of stainless steel. Does not require hot processing or other stress relief during production. Grade 316 is the most corrosion-resistant of stainless steel grades and maintains its strength at high temperatures. Grade 304 is the most widely used, and although it is somewhat less resistant to corrosion, it has good formability and weldability.

The standard type of magnetic stainless steel for sheet metal production is 400 series. Class 410 has less corrosion resistance but is susceptible to heat treatment. Grade 430 is an economical alternative to other stainless steel options and is used in cases where corrosion resistance is not a basic requirement, for example, for surfaces of devices treated with a brush. Because these materials tend to have an elastic deformation rather than plastic, they must be bent to obtain the final shape.

Spring steels Harden quickly and needs to be heated to relieve stress during melting. Points include 301, 17-4, 1095, and 1075. Spring-loaded stainless steel, as a rule, requires special equipment and technological processes, and it must be bent to obtain the final shape.


Aluminum, which is material at a reasonable price, has certain characteristics at various levels in accordance with the requirements of the application. Brand 1100 has a relatively low strength, but it is resistant to chemical and atmospheric influences, it is welded and plastic, which allows deep molding. 3003 brand is stronger and can be molded, welded, corrosion-resistant, and convenient. Grade 5052 is much stronger, but it is still subject to melting, welding, and corrosion. Mark 6061 is a corrosion-resistant and durable structural alloy, but it does not lend itself to melting. It is susceptible to welding, even if it loses some strength during welding.

Cold rolled steel (CRS)The cold-rolled steel process is used to smooth the surface of hot rolled steel, as well as to ensure a stricter tolerance during melting. CRS is produced from alloys 1008 and 1018.
