Do you sometimes wonder about the effects of metallizing on steel bridge girders? What are the advantages of this method?
How does it protect the steel? What surface preparation is required? What about durability?
In the coming days, Canam-Bridges experts will help you to demystify the metallizing process. If you do not find an answer to your questions, feel free to send us your questions and we will offer you our support.
Metallizing is a common term used to describe thermal sprayed metal coatings. For corrosion protection of steel elements, it refers to the thermal spray of molten zinc or aluminum alloys as a direct coating on steel surfaces. This is accomplished by feeding the metal in either wire or powder form to an application gun where it is melted and propelled onto the steel surface to be protected. Upon contact, the zinc “splats” cool instantly, creating a solid barrier that isolates the steel substrate from the environment.
