Sidewalk street tree gate???

Hi I just received my street tree this morning and I am so happy but I would like to put a gate around it high enough so that people will not let their dogs in and just enough for me to get debris. does anyone know of a steel company that can do a job like this??

Thanks
Sarah from Bed-Stuy
