If you took items that did not belong to you without permission from the owner, you had no right to take the metal poles that you are writing about. Since you had no permission to take something that did not belong to you, you are now being charged with grand larceny for what you did.I recommend that you consult with a criminal defense attorney to defend you with respect to the criminal charges you are now facing. Hopefully an experienced criminal defense attorney will assist in resolving this dispute to your satisfaction.Good luck.
