When metals are cut, bended and assembled into various sizes and shapes, the process is referred to as metal fabrication. Usually, it is in a fabrication and machine shop where this work is done and there are various tools and processes like forming and welding are being performed.
Specialization of fabrication can also be enumerated, like brazing, shearing, forming, extrusion, forging, heat treatment, powder coating, punching, casting, spinning, and chipping. Electrical, prototyping, machine design and hydraulics are other forms of specialization which are of higher level.
Metal fabrication uses several raw materials like plate metal, formed metal, tube stock, square stock, welding wire, castings, hardware and fittings. To complete the processes of metal fabrication, it would undergo several stages, from cutting and burning, to forming, machining, welding and final assembly.
One use of metal fabrication is for the construction of different machines and structures. The popular materials that are used for metal fabrication are sheet metal and stainless steel, and these are used to manufacture several industrial and consumer products like loose parts, building structural frames and machines.
To produce the sheet metal, the metal is formed into pieces of thin and flat metals in several thicknesses called its gauge, and these can now be cut and bended into different sizes and shapes.
Sheet metal can also be done in coiled strips aside from flat pieces, and the metals that are used are aluminum, brass, copper, steel, tin, nickel and titanium. For decorative purposes, they sometimes use gold, silver and platinum.
Other uses of sheet metal fabrication are in the construction of products like bodies of cars, materials for building, and equipment for food processing and other things.
The property of stainless steel is very strong, coming out from its varying amounts of elements like alloy of iron, chromium and other elements, thus it can resists corrosion and stain and has a very low need for maintenance. Stainless steel is a completely recyclable material making it a very handy material for certain purposes.
The surface finishes and grades vary in stainless steel and you can opt for these variety depending on where you will use it, and so your choices would range from brushed finish to satin, mirror and coarse finish.
Out of the very intensive process of metal fabrication would result to the production of several industrial and consumer products. Many of the things that we use every day are manufactured using the main applications of metal fabrication which are the sheet metal fabrication and the stainless steel fabrication.
As metal fabrication come to its final stage after the cutting, joining, and welding are done, the metals are applied with protective coatings like powder coating or sandblasting, depending on your purpose and budget.
