The Work Of Custom Metal Fabricators

By Audrey McGuire


Creation of various designs by use of metal is known as fabrication. It involves; creating a design, cutting up metal pieces, bending them to various designs and then joining them to form a desired form. Therefore the sheets of metal gain a form thus giving it value addition. This process is used in creation of statues among other forms by custom metal fabricators.

The process of fabrication starts with designing. The structure preferred is therefore plotted on paper before the process starts. A detailed outline of the various equipments that need to be used as well as the joints is indicated on this. It also outlines the kinds of materials that are required for the final structure with clear measurements. Costing for the project is also based on this plan.

Once the necessary materials are in place, the metals are cut into the required pieces. This is done by use of various equipments that may be electronically powered or manual. These includes the laser cutter which is a common machine used for large pieces of metals and also used to cut a variety of them. The process of cutting includes chiseling, sawing and shearing among others.

After the pieces have been cut into the right sizes, bending starts. Bending is the process done to give shape to the pieces. It can be done manually by hammering. However, using a hammer is tedious and can only be used for light jobs. Use of power brakes is the most ideal method because it is much faster and accurate compared to the latter and can be used to bend thick metals.

For the parts to take form, they require joining though a process known as assembling. It involves welding and riveting among other processes. This is the most ideal stage which will lead to the realization of the final product. First to be joined are the structural steel parts and then followed by the outer covering. For the structural steel, welding and riveting may be used. For the covering, bending of the metal sheet to form crimped seam may be a better choice.

Fabrication is normally done in workshops. These workshops are specifically designed and installed with various equipments necessary for the process. They are referred to as fabrication shops and house the technicians who carry out these tasks. The shops are also fitted with various precautionary gadgets which includes the first aid kits and fire extinguishing cans.

There are various local and international companies that offer fabrication services. They normally employ highly trained technicians who undertake the work of fabrication. These experts are trained in the handling of various equipments which are used in the shops. They are also knowledgeable on issues of interpreting the drawings provided and transforming them into real objects.

Information regarding various companies can be accessed online. This info is provided in regard to their contact details and their area of expertise. Using search engines on the internet also yields good results on this. You will also find samples of the structures that the custom metal fabricators have constructed from their sites. Catalogues and quotations from these companies can also be accessed online.
