Understanding the Fundamental Processes Involved in Large Fabrication

Fabrication is an essential part of manufacturing in many industries. For various raw materials to transform into something useful, they must undergo different types of fabrication processes. Machining centres in Ontario such as Central Machine and Marine provide fabrication services for structural, commercial, and industrial applications. The use of advanced tools and machinery allows efficient and high standard fabrication.

A company in need of large fabrication in Ontario can hire expert services and expect to get quality standards. Understanding the different processes involved in steel fabrication will help a client find suitable services.

Shot Blasting

Shot blasting is a method of preparing a surface due for fabrication. Whether it is done before or after cutting will depend on the fabricators. A surface must be clean enough to allow welding and painting. Over time, steel accumulates dirt, grime, and other particulates and it’s essential to get rid of them. A surface that has undergone shot blasting will hold paint longer than one in its original state.

Cutting is one of the most crucial parts of the fabrication process. Traditionally, this used to be a tiresome practice because of the accuracy required. Nowadays the use of machines provides better levels of precision than before. A CNC machine shop can use different methods for cutting metal into desired shapes and sizes.

The use of heat is one alternative that facilitates the cutting process. It consists of using machinery that mixes different gases to trigger exothermic reactions with the metal and cut through it. Besides flames, CNC machines use water jets and lasers to cut through metal plates. A fabricator can explain the components of each cutting technique and recommended the most efficient one for your fabrication needs.


In large fabrication Ontario processes that involve curved steelwork, the bending process will be vital. There are different bending methods facilitated by various machines to achieve a wide variety of shapes. Some of the techniques that a fabricator may use include tube bending, and section and plate bending. The type of metal and the curve requirements will dictate the best bending process.


Welding is the process that allows joining of metal parts. The process involves the use of heat to melt materials. Usually, there is an electrode that supplies the filler material that joins two parts. Welding processes differ, and each has its advantages during fabrication. A CNC machine shop will have welding tools that provide accurate results and minimise the risk of defects.

Other processes such as painting and galvanising come after assembling metal parts. The finishing touches will depend on the type of product and the specifications you give.
