Stress Relieving and Grit Blasting for steel fabrication in Ontario
Many people refer to stress relieving and grit blasting services as “sandblasting”. At Conrex Steel, we do not use sandblasting or sand as a grit blasting agent, in fact the use of sandblasting is not legal in Ontario. Stress relieving and grit blasting services at Conrex Steel use steel grit, and steel shot, to restore steel fabrications or prepare them for coating. We also have access to Pickling, Glass Bead, Polishing and other surface prep solutions. Feel free to reach out to us on any required solution.

FAQs about Stress Relieving and Grit Blasting
at Conrex Steel
Is grit blasting the same as sandblasting?
The process is similar, but Conrex Steel does not use sand as the blasting
medium because its use is restricted in Ontario for safety reasons. Grit
blasting uses approved abrasive media to clean steel surfaces and prepare
them for coatings or further processing.
What industries require post-weld heat treatment?
Post-weld heat treatment is commonly required in pressure vessel
fabrication, structural steel manufacturing, industrial piping, mining
equipment, energy infrastructure, commercial trucking, and heavy
industrial fabrication projects.
What size steel components can Conrex Steel process?
Conrex Steel’s facility is designed to process large fabricated steel
components using three high-capacity furnaces, large blast booth systems,
and heavy lifting equipment suitable for industrial fabrication projects.
Furnace 3:
60 inches wide × 54 to 45 inches tall with an arched interior ×
101 inches deep. Rated for temperatures up to 2,200°F.
What regions does Conrex Steel serve for stress relieving and grit blasting?
