Collaborative Engineering

Our expertise helps improve manufacturability and reduce costs.

Before we fabricate, form, laser cut, or create any sheet metal part, we always start with the same question: What material is this part made of? There is a wide variety of sheet metal you can select for your fabrication project, and GSM carries a broad selection. Our materials list below shows our standard sheet metal material selection. If you do not see your desired material, ordering specific material for our customers is something we do regularly.

All your aluminum sheet metal needs can be satisfied through GSM! We work with both 5052 and 6061 aluminum alloys in a multitude of different thicknesses. 5052 offers excellent corrosion resistance and formability, while 6061 provides superior strength for structural applications.

Aluminum
Attribute	Min	Max
Thickness	0.032″	0.125″
Grade	5052	6061-T6
ASTM	ASTM B209

If you are looking for a sturdy, shiny, and smooth metal for your part, look no further than cold rolled steel. It is strong, good looking, and will not shrink during the forming process, making for high precision parts with tight tolerances.

Cold Rolled Steel
Attribute	Min	Max
Thickness	0.036″	0.125″
Grade	CQ	DDS
ASTM	ASTM A1008

Easy to fabricate, corrosion resistant, and offering a long life span, Stainless Steel is a great option for your fabricated parts. GSM can supply all the stainless steel solutions you need across a range of grades for different corrosion and strength requirements.

Stainless Steel
Attribute	Min	Max
Thickness	0.038″	0.109″
Grade	304	316
ASTM	ASTM A240

Hot Rolled Steel offers better workability, little to no internal stress, and a lower cost than cold rolled steel. Compared to cold rolled steel, it has more rough edges and surfaces that may require deburring. It is ideal for structural parts where surface finish is less critical.

Hot Rolled Steel
Attribute	Min	Max
Thickness	0.134″	0.250″
Grade	CQ	HSLA
ASTM	ASTM A1011

What makes this steel special is the protective coat of zinc that improves the corrosion resistance of the material. This makes it more resistant to damage and protects the steel beneath from harsh atmospheric conditions. Galvanized steel is ideal for outdoor and corrosion-prone environments.

Galvanized Steel
Attribute	Min	Max
Thickness	0.060″	0.135″
Grade	G60	G90
ASTM	ASTM A653

Also known as Galvannealed Steel, this comes from galvanizing then annealing the sheet of steel. It has a matte grey color which is easily paintable with a more uniform coating. Galvanneal is the preferred choice when parts will be painted after fabrication.

Attribute	Min	Max
Thickness	0.061″	0.093″
Grade	A40	A60
