Copper is a natural metal that has a time tested immunity to oxidation. It has been used for centuries in many applications where it was vital that rust and corrosion would not affect its function. It has survived unchanged since the beginning of time -- with the exception of turning a natural Patina or Verde color.
Brass is an alloy derived from copper and has the same corrosion resistant properties. Copper and brass can never rust, rot or corrode, even in the harshest outdoor environments. This is why these metals are the only choice for outdoor lighting. Weve all seen what happens to many other types of outdoor fixtures that have been in the garden for any length of time.
MJM stands behind our unbeatable lifetime warranty for all of our solid copper and brass fixtures. This warranty also extends to our chemical finishes -- which are NOT a paint or powder coat. All of our chemical finishes are basically an accelerated form of what would happen naturally, given enough time. While natural Patina starts in a bronze color and then changes to Verde, our process also creates rusty or black looking elements.
Copper and brass are not just for coastal environments. In modern landscape conditions with constant irrigation, fertilizer and soil amendments, a coastal environment is created in almost every garden. It is difficult for anything to survive in such harsh surroundings; therefore you can trust MJM finishes to remain beautiful and functional until the end of time!
