How do we achieve waterproof protection?
All these layers create what we call a "sandwich barrier", further ensuring protection against moisture and corrosion.
- Lacquered with polyester powder coating in micro-textured anthracite grey (RAL:7016): for a perfect finish and increased protection against corrosion.
- Chrome passivation: We apply a chrome passivation to further increase corrosion protection. It strengthens the resistance of the parts and prolongs their service life.
- Electrolytic zinc plating: We apply a layer of zinc at low temperature to protect the parts against corrosion.

The durability of our waterproof treatment varies depending on environmental exposure and where the product is installed. Under normal low corrosion conditions, it can last for more than 10 years. It is important to note that durability is based on laboratory testing, but each actual location may involve different exposures.
We recommend reading the outdoor guide or speaking to our customer service team for specific details about durability in your area. They are the experts who will give you all the information you need.
The waterproof treatment is suitable for most environments (with the exception of very aggressive atmospheres). Its durability may vary depending on where the product is installed and the level of environmental exposure (coastal areas, urban and industrial atmospheres, high humidity...). There are different levels of durability depending on the corrosion classification of the environment.
Our treatment provides additional protection, increasing durability against corrosion-causing weather conditions - call us for more details on durability for your specific environment!
The main difference is that the decking is an extra element that is laid on top of the mezzanine wood flooring. This is because the mezzanine flooring alone does not have the appropriate properties to withstand outdoor conditions.
Outdoor decking provides an extra layer of protection and durability, ensuring that your outdoor space remains strong and resistant to rain and other elements of weather.
For total protection, we recommend purchasing the waterproof treatment and outdoor decking together. They are the ideal combination to ensure your mezzanine is ready for any season.
