This innovative signage product we’ve been manufacturing for nearly 5 years continues to be a game-changer when it comes to the look & feel of a naturally-rusting cor-ten steel finish. Learn the numerous benefits of using aluminum over steel when it comes to signage.
A primer and iron flake solution are applied to an aluminum panel, then an acidic solution is sprayed on to begin the “rusting” chemical reaction. Depending on the desired rust level, the sign could sit for a couple hours or overnight. The longer, the rustier. Then the finish is rinsed off and clear coated to ‘stop’ the continued degradation of the finish.
Just like naturally occurring rust, there is no specific pattern to the rust finish, it’s all natural since it is the same rusting process…just sped up a little, then stopped.
Since aluminum is a more malleable metal, it responds better to bending and cutting. Architectural sign designs with curves and bends are possible with this material and so is internal illumination. Whether backed up, flush, or push through, creating cnc-cut logos and letters are much easier using aluminum than using steel. With an aluminum product, cnc-routing letters on the flatbed is a standard and more cost-efficient process since aluminum is an easier metal to fabricate.
This faux rust finish, using aluminum, doesn’t continue to degrade over the years. The finish is clear coated and essentially stops the “rusting” process in its tracks. This is beneficial so you won’t see rusty drips on your letters or your base. The clear coat stops the rusting process and also allows this sign finish to be more vandal resistant and easier to clean than traditional painted finishes.
We are just very “pro aluminum” when it comes to all things signage fabrication. We almost always use steel posts for installation as well as some steel structure in the engineering of our signage. So steel sees the love too.
