Information of Sheet metal

- Apr 09, 2019-

As a leading manufacturer of metal enclosures for more than 20 years in Shenzhen China,we have many types of sheet metal box.Compared with extruded aluminum box,the sheet metal box with more favorable price,flexiable design.Widely used in industrial electronic,instrument equipment,medical area etc.Today,I'll introduce some information about the sheet metal.

What's sheet metal

Sheet metal is metal formed by an industrial process into thin, flat pieces. Sheet metal is one of the fundamental forms used in metalworking and it can be cut and bent into a variety of shapes. Countless everyday objects are fabricated from sheet metal. Thicknesses can vary significantly; extremely thin sheets are considered foil or leaf, and pieces thicker than 6 mm (0.25 in) are considered plate steel or "structural steel."

Main material for sheet metal

Cold Rolled Steel (CRS) CRS is pressed into a sheet in a cold state at the steel foundry. It has a more homogeneous composition than Hot rolled steel (HRS), which allows better heat conductivity and is easier to machine. Most of our steel sheets are CRS as well as our bar stock that the machine shop uses.

Hot Rolled Steel (HRS) is formed into a sheet in a molten state and rolled flat while still hot. HRS is usually of less quality than CRS, is more difficult to machine due to variable composition in the metal.

Stainless Steel (CRES) is an alloy based on chromium and steel and is categorized by its resistance to corrosion. The gauge thickness is the same as regular steel. Stainless is much harder than regular steel and is not easy to work with in some respects. 

Aluminum are mixtures of aluminum with other metals, often with copper, zinc, manganese, silicon, or magnesium. There are too many alloys of aluminum to list. The number after the 4 digit code is the tensile strength or temper of the alloy that ranges from T0 to T6. T0 is soft, and T6 is full hard. VIP uses, 5052-H32, 6061-T6, 6061-T4, 2024-T0 for most of our parts.

The main material we used for sheet metal box is iron,aluminum,stainless steel etc.Since we accept custom service,so customers can choose the material according to your products,and we can design for you.
