The stainless steel screen, which holds the seed, is welded to two stainless steel rods. These rods fit into grooves at the corners of the piece. The rods hold the seed screen in place much like a hammock, and also serve as perches for birds. The entire screen and rod section is removable for cleaning.
The steel is treated with primer before being sprayed with Rustoleum enamel. They can be finished in a variety of colors if you are interested. Just check the color chart below and indicate a different color preference when ordering
