Structural Steel Fabricators in Toronto – The Process

August 26, 2016

The work of structural steel fabricators in Toronto involves manufacturing steelwork components, which when assembled and joined, form a complete frame. Materials and components used include: bolts, coating systems, proprietary products, cold formed sections, and plates. High quality production standards are enhanced by the accurate details transmitted to Computer Aided Manufacturing by the Computer Numerically Controlled machinery, where the Computer Aided Design is linked directly to. Structural steel fabricators in Toronto typically start fabrication project processes with standard preparation techniques, which include:

  • stockyard assessment and sorting
  • shot blasting or abrasive cleaning
  • cutting and drilling

At the steel stockyard, plates and sections are organized and moved to the storage area. They are unloaded and stored as they wait for processing in fabrication lines. Much material is stored so as to enable stable and streamlined processing. Sections and plates are then shot blasted or abrasive cleaned until a clean finish and smooth surface is achieved. This is necessary in order to prepare the surface for welding. In addition, abrasive blast cleaning preps a surface for painting as well as protective coating. Sections are then cut to length and plates profiled to desired shape and size. Various tools and techniques are used, namely:

  • circular saws
  • gas or flame cutting
  • laser or plasma cutting
  • drilling and punching

Structural steel fabricators in Toronto use tools like circular saws in order to ensure sections are cut to length accurately and at an efficient speed. Flame cutting uses oxygen and propane to preheat sections, after which pure gas is directed to the preheated area. A slag is created that is blown away by the oxygen jet, enabling continued cutting of the material. Bending is then done which can be section, plate, tube bending, and also press breaking. Tee splitting is then done followed by profiling of tubular sections. The fabrication project can finally be welded together until finished.
