Metal fabrication is a process that is common especially in the construction and manufacturing industry. During metal fabrication, raw materials are simply converted into processed products that are utilized in construction of bridges, machines as well as buildings. One of the most commonly used metals for fabrication is structural steel due to its flexibility, tensile and durable properties. There are various fabrication processes involved in the making of steel sections during steel fabrication. Some of these processes include cutting, folding, machining, punching, shearing, stamping as well as welding. During metal fabrication, the first stage is cutting. During cutting, steel is cut into smaller pieces using a saw, plasma torch, a water jet as well as lasers. Other cutting techniques used include chiseling, numerical control as well as shearing.
When fabricating structural steel, press brake is utilized during folding. In order to make certain steel sections, steel has to be bent or folded. Air-bending a sheet of metal during folding is essential as it helps one to acquire the desired form of the metal for ease of use. The press brake used has a set of dies that pinch the metal sheet in order to form a crease. The next process is machining whereby unwanted materials on the metal are removed in order for the designer to acquire a particular shape. One can either choose to rotate the metal against a cutting tool or use a rotating cutting tool on a stationary metal piece during machining.
In order to create a hole in a metal sheet, it is punched using a punch press. In order for the metal to get the perfect hole shape, one should ensure the die and punch are of similar shape. Cutting of straight lines onto a flat metal stock is done through the process of shearing also referred to as die cutting. A die is used in stamping with a portion of the metal raised. Welding is the process through which two metal pieces are attached in order to form a bigger metal sheet or separate steel section. Metal designers use different techniques during welding which depend on the design of the metal structure and the metal itself.
Metal fabrication is very beneficial as it helps strengthen the quality of the metal. This makes the steel more suitable for use especially in commercially designed buildings. Energy sector projects also make use of fabricated steel. Fabrication companies usually produce metal products depending on how the client has specified. Fabricated steel is preferred by most clients since it is cheaper unlike other alternatives. Another reason clients prefer it is because steel fabrication is cost-effective.
There are various sectors that utilize structural steel such as transport, infrastructure, manufacturing as well as construction.
