Surface Treatment Process Part One: Galvanizing Treatments

Bossard Proven Productivity means providing products that you can rely on long-term. This means that we will do everything we can to assure reliable, trust-worthy materials.

For our fasteners, different surface treatment processes are used to make them last. Galvanization is a system that involves the immersion of the steel product into molten zinc that’s been heated to a temperature between 440°C and 470°C.

During galvanization, the steel is lowered inside the kettle until it matches the temperature. A benefit of using this type means that it generally takes less than ten minutes, depending on the thickness of the steel. With a dull and rough finish, it provides corrosion protection; with our “galvanization-passivation” process, it improves the appearance of the fasteners.

In order to prepare the steel for galvanization, among other preparations, it is first cleaned and rid of grease. Next, the product undergoes the treatment and endures a “post treatment” process. During the surface coating, a metallurgical reaction occurs, which is a diffusion measure that assures a regular thickness throughout the treated part.

The color may change after a certain length of time; however, this special treatment can last up to 50 years. Variation in length of time occurs based on the location of the steel. Under harsh conditions, its life will be closer to 25 years, rather than 50.

Similar to other technology, there are always new developments in this process, and Bossard Proven Productivity is always ahead of the game. Our clients are guaranteed innovation and reliability when working with our brand. We care for the parts we produce from engineering to production, always keeping our customers in mind.
