In construction and manufacturing industries, metal fabrication is a very common process. 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. 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. Cutting is the first stage of metal fabrication. During cutting, steel is cut into smaller pieces using a saw, plasma torch, a water jet as well as lasers. During steel fabrication, other cutting techniques utilized include chiseling, numerical control as well as shearing.
During folding, a process called press brake is used. Folding or bending of steel is important in order to make certain steel sections. 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. After folding, the steel goes through machining whereby unwanted materials are removed from the steel metal in order to come up with a desired shape. During machining, the metal designer has an option to either use a rotating cutting tool on a stationary metal piece or rotate the metal piece against a tool for cutting.
A punch press is used to punch a piece of metal in order to create a hole in it during punching. One should ensure that the die and punch are of the same shape for the hole shape to be perfect on the metal. The process of die cutting or shearing is done in order to cut straight lines onto a flat metal stock. A die is used in stamping with a portion of the metal raised. Welding involves two pieces of metal becoming attached in order to form a large structure or separate steel section. Metal designers use different techniques during welding which depend on the design of the metal structure and the metal itself.
Steel fabrication is very effective as it helps to strengthen the metal in terms of its quality. Better quality steel is more suitable for commercially designed buildings. Steel produced as a result of welding is also ideal for use during projects in the energy sector. Fabrication companies usually produce metal products depending on how the client has specified. Most clients prefer working with fabricated steel since it is more affordable unlike other alternatives. Another reason clients prefer it is because steel fabrication is cost-effective.
Structural steel is used in various sectors such as infrastructure, oil and gas, transport, manufacturing and construction.
