Sheet metal is an industrial product made from various metals into thin, flat pieces. It is an essential raw material in most fabrication process of many other pieces of equipment. It can be made into many different shapes of different sizes. The thickness can vary a lot depending on the purpose it is meant for. Those pieces that are too thin are referred to as foils while those with thicknesses wider than six millimeters are referred to as plates.
The thickness of sheets is measured through a traditional, non-linear measure called gauge. If the gauge number is large, it implies that the thickness is thin. Common gauge measurements range from 30 to about 8 gauge. For all gauges of sheet metal Los Angeles companies deserve to be given a visit. The gauge however differs between pieces that contain iron and those that do not.
This product is produced from several metals allowing it to have use in different settings. Examples of metals used include tin, steel, copper, brass, aluminium, titanium, iron, nickel, and bronze. Silver, gold, and platinum are used on sheets used for decorative purposes. They are available for sale in form of coiled strips or flat plates. A roll slitter machine is used to make the coiled strips.
Almost all industries make use of sheet metal. Any use of the sheets is determined by the material it is made from. The commonest uses include making of medical tables, airplane wings, cabinets, auto bodies, horse tack, utensils, casings, and rooftops for various buildings. Laminated steel cores or materials that have magnetic permeability like copper or iron metals are used to make transformers and electric devices.
In building, steel sheet is preferred more than other materials. This is due to its high quality and cost effectiveness. There are three main grades of stainless steel in use, that is, 316, 304, and 410. Grade 304 is the most common of all the other grades. It has an outstanding level of resistance to corrosion and maintains formability and weldability quite nicely. The level of corrosion resistance and strength of grade 316 at higher temperatures is however higher than that of grade 304. It is therefore used more in manufacture of pumps, chemical equipment, valves, and marine applications.
Aluminium is also a commonly used metal because of its cost effectiveness, wider range of options, and high level of flexibility. It comes in four major grades, that is, 6061-T6, 5052-H32, 3003-H14, and 110-H14. Grade 1100-H14 comes as commercially pure form of aluminum. It has the highest resistance to weather and chemicals. Its high ductility allows deep drawing and welding although it has low strength. Common applications are in jewelry and light reflectors.
In Los Angeles, this industry creates a lot of revenue to the local government. Most of the raw materials used in the industry are mined locally while the final products are consumed locally or exported to foreign destinations. Workers in this industry are referred to as tin knockers or tin bashers. Several hundreds of people are employed annually into this industry in different positions.
The cost of sheet metal depends on the metal it is made of. The cost is affected by thickness, grade, finish, quality, and size. Worldwide prices also differ widely.
