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. Most manufacturers prefer using structural steel during fabrication because it has good qualities such as durability, flexibility as well as being tensile. Steel fabrication makes use of a variety of fabrication processes in order to make steel sections. The various fabrication processes involved in steel fabrication include shearing, welding, machining, punching, stamping, cutting as well as folding. The first stage of the fabrication process is cutting. During cutting, steel is cut into smaller pieces using a saw, plasma torch, a water jet as well as lasers. Chiseling, numerical control and shearing are other cutting techniques used during steel fabrication.
During folding, a process called press brake is used. Folding or bending of steel is important in order to make certain steel sections. Folding helps to air-bend a sheet of metal into the desired form for ease of use. In order to form a crease on the metal sheet, the press brake used has a set of dies within it that pinch the steel metal forming the 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.
During punching, a metal piece is punched by the use of a punch press in order to create a hole in it. In order for the metal to get the perfect hole shape, one should ensure the die and punch are of similar shape. The process of die cutting or shearing is done in order to cut straight lines onto a flat metal stock. During stamping, a portion of the metal sheet is raised when using a die. Welding is the process through which two metal pieces are attached in order to form a bigger metal sheet or separate steel section. The various welding techniques used by metal designers usually depend on the metal and its structure.
Quality of steel is greatly improved through steel fabrication. Strengthening steel helps to make it more suitable for construction projects. Energy sector projects also make use of fabricated steel. Clients usually offer their specifications to metal designers in order to get their desired metal. Since it is more affordable, most clients prefer working with fabricated steel. The process of fabricating structural steel is very cost-effective making it favorable.
Structural steel is used in various sectors such as infrastructure, oil and gas, transport, manufacturing and construction.
